The Human Immunodeficiency Infection ( Hiv ) Essay
1. The Human Immunodeficiency Infection ( Hiv ) Essay
The human immunodeficiency infection (HIV) has claimed the lives of more than 35 million individuals since its emergence. In 2014, an estimated
3000 individuals in New Zealand was reported to be living with HIV. And, although HIV doesn 't discriminate, the brunt of this epidemic's impact has
disproportionately affected specific populaces.
Men who have sex with men (MSM) have a higher probability of contracting HIV since the virus is eighteen times more communicable through anal
sex when compared with vaginal sex (1). Furthermore, at present, 1 in 15 gay and bisexual men in New Zealand are HIV–positive (2). This, when
coupled with the fact that gay and bisexual men comprise only a small proportion of the New Zealand population, means that they are more closely
linked, and, consequently, have a smaller pool of potential sex partners, contributing to a faster, more aggressive pattern of transmission amongst
MSM. The rate of HIV diagnosis among MSM in New Zealand was low and steady in the late 90s. However, the number of new HIV diagnoses in this
population tripled by 2005 (3). Evidently, MSM in New Zealand are more susceptible to new HIV infections today when compared to 20 years ago.
The explanations behind the sharp increment seen around 2001 and 2005 are complicated and multifarious, but can be encapsulated into four
fundamental foci. The major, overriding reason for the constantly rising number of HIV–positive MSM living in the populace has been the successful

2. Clinical Manifestations Of Hiv Infections
1–A 20–year–old cocaine abuser with a recurring upper respiratory infection is examined and is noted to have white patches in the oral cavity along
with parotid enlargement.
a. What history is pertinent to the examination of this patient?
HIV is manifested clinically as the development of recurrent, often severe, opportunistic infections, such as respiratory infections, and oral candidiasis
(white patches), due to their compromised immune system. Parotid enlargement is another common finding in person with HIV, and the use of illicit
drugs, especially by injections positions the patient at high risk of acquiring HIV infection.
Then, the history of present illness, past medical history, family, and personal and social history should... Show more content on Helpwriting.net ...
Oral white patches suggest a yeast infection of the mouth named candidiasis (trush), and it is the most common oral condition in people with HIV
infection. Researches estimated that 9 in 10 people with HIV present at least one oral condition related to HIV disease. This may be the first sign of
immune suppression and the reason why physicians recommended HIV testing. The immune system weakens progressively over time and becomes
susceptible to bacterial, viral, fungal and parasitic (opportunistic) infections. Another infection (viral) with oral white patches manifestation is the hairy
leukoplakia, which is believed to be caused by Epstein–Barr virus mononucleosis, also very common in HIV–related oral conditions("HIV and the
mouth", 2011).

It has been found that HIV infection and immune activation resemble the immunology process on the elderly. The relation between HIV infection and
inflammation is similar to the relation between age and inflammation.30
Pawlec et al defines immunosenescence as the decrease in immune function due to age–related changes involving various cells: decrease in function,
alteration in natural and adaptive immune system, or the imbalance between both factors. (89) Decrease in immune system function contributes to the

5. Taking a Lookat Hepatitis C Virus
Globally, an estimated 150 million people have been infected with hepatitis C virus (HCV). HCV is the major cause of cirrhosis and liver cancer and
one of the most common indications for liver transplantation (Simmonds, 2004).There is serious concern about the growing problem of the HIV and
HCV prevalence in Africa, where the major route of transmission of HIV is through the sexual route. Co–infection with HCV and HIV is common due
to shared routes of transmission – via blood and blood products and sharing of needles for injecting drugs. About 40 million people are estimated to be
infected with HIV worldwide of which approximately 4–5 million are co–infected with HCV (Alter, 2006). Co–infection with HIV and HCV are
common due to shared routes of transmission, however, there are differences in the ways that these viruses are transmitted in the developed and
developing countries (Ocama and Seremba, 2011).
Burden of HIV and HCV co–infections in Africa
There have been a number of studies in Africa that have investigated the prevalence of HIV and HCV co–infections in various countries in Africa.
Generally, the distribution of HIV and HCV co infections in different regions of Africa differs by countries. The prevalence of HIV and HCV
co–infections range from as low as 0% to 99.7% (Table 1).

6. Hiv Virus Research Paper
The human immunodeficiency virus gets its name by the sole species it affects and the characteristic damage it does to the body, which is also
known as HIV. Viruses are notorious for the mode in which they reproduce; a virus enters the body, seizes the body's cells, and uses it as a host. This
is the only way for viruses to replicate. HIV takes over the body's T cells, also known as CD4 cells, which are important to defend the body from
various antigens. Normally, T cells would respond to infection and diseases by neutralizing, creating antibodies to fight off the antigen the next time it
comes around, or lessen the effects it has on the body. Infections such as pneumonia that would make a regular person incredibly ill could be fatal to
someone ... Show more content on Helpwriting.net ...
Two to four weeks after infection a person can experience flu–like symptoms. This is when the virus begins to rapidly replicate, and during this time is
when the HIV virus count is highest and the CD4 count drops rapidly. The lower the CD4 count the more susceptible the body is to other infections.
Although HIV can be spread during any stage, there is a higher chance of spreading the virus because of the high virus load per cubic millimeter of
blood. The second stage is known as clinical latency also known is inactivity, dormancy, asymptomatic HIV, and chronic HIV infection. Amid this
aspect of infection the virus is active in the body, but there are low levels in the blood. Contagion is still existent, so precautions are pertinent.
Affected humans can reach chronic HIV infection stage rapidly, but can be prolonged for a more than a decade with proper treatment. The final stage
of HIV infection is known as AIDS, which means acquired immunodeficiency syndrome, meaning that the CD4 cell count is less than 200 per cubic
millimeter of blood. Normal CD4 counts range from 500–1600 per cubic millimeter. During this stage the body can no longer protect itself from
antigens. Common infections such as the common cold can ultimately be fatal to the

Overview of HIV Disease in India India has the third largest population of people living with HIV, behind Nigeria (second largest) and South Africa
(largest population) ("India has 3rd Highest Number of HIV Infections," 2014). There are approximately 2,100,000 [1,700,000 – 2,700,000] people
living with HIV in India and there is a prevalence rate of 0.3% [0.2% – 0.3%] for adults aged 15 to 49 ("HIV and AIDS Estimates in 2013," 2013).
There is a high risk for HIV infection in India due to the high rate of unprotected sex, low use of condoms, injecting drugs with HIV contaminated
needles, the low social and political status of women and the negative stigma associated with being HIV positive ("HIV/AIDS in India," 2012).
The main focus of the government on HIV and AIDS is to spread awareness in the population and to convey the importance of protected sex and
blood safety. These goals about HIV infection prevention are addressed by various organizations in India and in the world, such as the AIDS Society
of India and UNAIDS ("HIV/AIDS in India," 2012). However, the majority of the HIV population in India does not know their HIV positive status,
coverage of HIV treatment is only 36 percent and 64 percent do not have access to HIV antiretroviral treatment options ("India has 3rd Highest

8. Hiv And Its Infection Dynamics
Abstract HIV is one of the most feared diseases around the globe since its "discovery" in 1981. HIV stands for human immunodeficiency virus and
is caused by Lentivirus, which is a subgroup of Retroviridae (Douek et al. 2009). HIV is one of the more dangerous diseases known because there is
currently no known cure and will infect roughly 50,000 people in the United States alone each year (CDC 2016). HIV is a terrible disease that has taken
the world by storm. While originally only known as a homosexual disease, that false perception has been shattered as the disease continued to spread.
The origin of HIV is not entirely known, though there is strong evidence to support the idea that it originated in a chimpanzee in West Africa. They...

The first international report on this yet unnamed immunodeficiency syndrome described five young homosexual men in Los Angeles with
Pneumocystis carinii pneumonia. This led to other reports of more patients who were abnormally immunodeficient. The fact that many of these patients
were either homosexual or drug abusers led researchers to strongly suspect that the disease was blood borne and sexually transmitted (hivinsite 2016).
HIV was initially viewed as a homosexual disease with some drug abusers also being exposed in the United States. The CDC put together a task force
to monitor the outbreak of rare opportunistic infections that were known to occur in immunocompromised individuals (Basavapathruni and Anderson
2007). The disease was unknown at the time and HIV was known by many different names as no one had yet isolated the causative agent of the
disease. Robert Gallo and Luc Montagnier both went on to publish findings that identified different aspects of HIV. Gallo claimed that HIV was similar
to Human T–cell Leukemia Virus and named it as HTLV–III while Montagnier claimed that HIV was immunologically independent from HTLV, and
named it Lymphadenopathy–associated Virus or LAV (Gallo et al. 1983). Later, the two names were merged into human immunodeficiency virus or
HIV by 1986.

What is HIV/AIDS?
HIV stands for Human immunodeficiency Virus. This virus weakens a person 's ability to fight infections. During HIV infection, the virus attacks and
destroys the infection–fighting CD4 cells, a type white blood cell. The loss of CD4 cells makes it difficult to fight infections, and so, one would be
most susceptible to any and every illness. A person with the loss of 200 and more CD4 cells is said to have the more advanced stage of theHIV
infection, acquired immunodeficiency syndrome or AIDS. This is the stage at which all of a person's ability to fight infections is lost.

Alcohol and drugs
With the use of alcohol or drugs, be very careful. Being under the influence can make one careless about practicing safer sex.
Never share intravenous (IV) needles, syringes, cookers, cotton, cocaine spoons, or eyedroppers with others if you use drugs.
If someone already has HIV
If you are infected with HIV, you can greatly lower the risk of spreading the infection to your sex partner by starting treatment when your immune
system is still healthy.
Experts recommend starting treatment as soon as you know you are infected.
Tell your sex partner or partners about your behaviour and whether you are HIV–positive.

11. Hiv And Human Immunodeficiency Virus Essay
HIV has been a pandemic that has affected the world relentlessly for many years in a never–ending circle. HIV, or Human Immunodeficiency Virus, is
the virus that is spread through certain bodily fluids and can lead to AIDS (Acquired Immunodeficiency Syndrome). HIV attacks the immune system by
destroying CD4+ T cells, which leaves the person infected with HIV vulnerable to other infections, diseases, and other complications.1 Once this
virus is acquired, the human can never fully rid itself of this pathogen. If left untreated, HIV reduces the number of CD4+ cells in the body whom
sole duty is to protect the body from infections. 2 Many scientists have postulated on where the virus was first introduced. It has been assumed that
the virus was first encountered humans whom were hunting and eating chimpanzees in Central Africa and the virus has spread like wildfire since
then. Data over the years have shown that the virus has existed within the United States since at least the mid to late 1970s. 3 No effective cure for
HIV currently exist although many vaccine studies are underway around the world, but with the proper treatment and medical care provided by the
medical team, HIV can be controlled and have low transmission rates. The medicine we use to treat HIV is referred to as antiretroviral therapy or
ART. When a person infected HIV adheres to the medication correctly, it will allow for them to live longer and have healthier lives. 2

12. Hiv / Aids : A Health Concern And Despite The Knowledge Of...
HIV/AIDS is a health concern and despite the knowledge of the disease, the infections are increasing especially amongst Blacks. This topic is
particularly of interest to me because I feel that there is a greater need to apply sociology to explain why the rate of infections is increasing amongst
certain demographics principally in the blacks/African American in the United States and not the people of whiteness. Blacks/ African Americans are
not to blame for the HIV/AIDS, the social environment in which they live affects the individuals and in turn the way they think, act and behave.
Corresponding to Lisa McIntyre (The Practical Skeptic, 2011), the sociological concept of social imagination "disregards biases against individuals and
appeals to sources outside the individual" or social forces to explain behavior (p.31) furthermore, the concept of social imagination allows one to tackle
the problems from the grassroots and promises significant change in the results. Definition and Statistics Conferring to the Center for Disease Control
and Prevention (CDC), HIV stands for Human Immunodeficiency Virus which leads to Acquired Immunodeficiency Syndrome (AIDS), (CDC, 2014).
HIV affects the immune system that is the CD4 cells causing the weakening of the immune system (CDC, 2014). Weakening of the immune system
leaves the body defenseless from new infections. At this stage, one is then declared to have Acquired Immune Deficiency Syndrome (AIDS).

13. Genetic Determinants Of Hiv Infection
Genetic determinants of HIV infection:
HIV has two major types: HIV–1 and HIV–2. HIV–1 has four groups M, N, O and P. These groups are further classified into subtypes. Group M is a
major infecting group worldwide contributing to 90% of HIV–1 infections. Group M is classified into nine subtypes (A, B, C, D, E, F, G, H, J and K).
Subtype B is predominantly found in America and Western Europe. The susceptibility toHIV–1 infection, transmission of disease, and response to
retroviral therapy depend on the genetic determinants of the host cell. These genetic determinants vary in populations and among patients. These
genetic variants regulate chemokine co–receptors and ligands that involve in the entry of the virus, major histocompatibility complex, killer cells Ig
like receptor and cytokines, and TRIM5О± motif and apolipoprotein B mRNA–editing enzyme, catalytic polypeptide–like 3G (Kaur and Mehra, 2009).
In genome–wide association studies performed in European population, it was shown that Human leukocyte antigen (HLA) class I variation (Eg.
HLA–B*5701) is the major contributor to viral set point and CD4+ T cell decline (Fellay et al., 2010). Cohort study of genetic polymorphism in
chemokine receptors in Indian population has shown that protective CCR5 О”32 variant is rare and CCR5HHE carrying *59402A has the high

Uganda in the past has been at the forefront of the fight against Human immunodeficiency virus infection – acquired immunodeficiency syndrome (HIV
/AIDS) in Africa and it became one of the earliest success stories (USAID 2004).
However, the HIV–AIDS prevalence rates have been rising again drastically since 2011.
Uganda now seeks for "Preventive Measures" lessons from other countries that had used it before as "a learning and reference point" (Monitor
Uganda, May 8, 2013). Therefore, the question of interest in this paper is why are the rates of HIV–AIDS suddenly increasing in Uganda? According to
the 2011 AIDS Indicator survey, the HIV–AIDS prevalence rates now stand at 7.3% from the previous 6.4%. The number of people living with
HIV–AIDS and its related diseases is currently 1.6 million from 1.2 million. (Uganda HIV and AIDS Country Progress report, 2013). In this paper, the
possible hypothesis to the question of interest will be best illustrated basing on these reasons as listed below:
Government involvement in the HIV–AIDS campaigns has reduced compared to the past where the president himself spearheading campaigns against
HIV–AIDS
The economic growth rates of the country
The ever growing Ugandan population Before commencing in to the details of the hypothesis, there is need to have a clearer understanding of the

Congenital Human Immunodeficiency Virus, also called Vertical HIV, is a serious epidemic arising from passage of the virus to an infant from a
maternal infection. The disease can have severe symptoms for the infected newborn and is almost always fatal to the child. The fetus has a 25%
chance of infection while in utero and a 20% – 50% ( depending of the country) chance of infection during the birthing process although a cesarean
birth significantly lowers the probability of neonatal infection. The severity of the mothers HIV infection determines the chances of a fetal infection
meaning the more advance the disease in the mother the high the possibility of transmission through placental cord blood. Infection can also occur from

The juxtapositional co–receptor attachment to the host membrane encourages the GP41 protein to initiate fusion by collapsing into a hairpin loop
structure bringing the two membranes in close proximity. Thevirus then injects the contents of the virion including machinery enzymes and the RNA
genome into the host cell where a dsDNA molecule is made and integrated into the host. The reverse transcription process has a high mutation rate
because the viral reverse transcriptase enzyme is unable to detect or repair any mistakes as it forms the dsDNA. After the new dsDNA molecule is
made it is transported to the nucleus of the host and integrated into the host genome. The HIV genome will either remain in a lysogenic state within
the host or if actively stimulated new HIV viruses will be constructed and released to infect neighboring cells. The ability of the virus to choose its
co–receptor is called viral tropism and determines its virulence and disease progression rate. If the virus binds with the co–receptor CCR5 it is called
macrophage–tropic (M–tropic) and characterizes most HIV infections. The M–tropic variant is regarded as less virulent because it is nonsyncytial.
Some mutations of the CCR5 gene lead to a partial immunity to the virus and can slow the disease and in some cases prevent infection of the M–tropic
HIV varient. Also patients with high levels of CCR5 soluble chemokines are more resistant to the virus. The CXCR4 chemokine co–receptor is

16. Acute Human Immunodeficiency Virus ( Hiv ) Infection
Acute Human Immunodeficiency Virus (HIV) infection is the small period of time after a person has been exposed to HIV and before they have
seroconverted. Seroconversion is the process in which the body starts to create antibodies to fight the HIV virus (Pietrangelo, 2013). During this
period of time, which is usually a few days, the virus replicates rapidly. The rapid replication results in extremely high amounts of HIV in the blood
because the body has not had time to respond to the infection. As the viral load increases more CD4 white cells are destroyed. CD4 cells are a
responsible in protecting the body from infection. When these cells are destroyed they no longer are able to adequately activate the body 's immune
system. (AIDS.GOV). ... Show more content on Helpwriting.net ...
Signs/symptoms of Acute HIV Infection Including H&P
Not all patients with HIV will have signs or symptoms during the acute infection phase. If a patient is having symptoms they can often times think that
they have the flu. Acute HIV infection symptoms can show up 2–4 weeks after exposure and last from a few days to several weeks (Cherney, 2014). If
they are exhibiting symptoms they may present as having a fever, swollen lymph nodes, skin rashes, myalgia, diarrhea, oral ulcers or thrush, and
fatigue. Lab results may also show leukopenia, thrombocytopenia, or an elevation in transaminase (DHHS, 2015). Differential diagnoses include the flu
or Epstein– Barr Virus since these also present with similar symptoms.
A thorough health history must be taken with patients before an exam in order to identify risk behavior. Important things to ask about are sexual
history, partners and possible exposures, any drug use (especially intravenously), and any current STI's (HRSA, 2014). Upon physical exam things to
look for or may see with an acute HIV infection would be ecchymosis, purpura, petechiae, Kaposi sarcoma, lymphadenopathy, oral candidiasis, or

18. Human Immunodeficiency Infection ( Hiv )
Human immunodeficiency infection (HIV) is the infection which causes the illness, AIDS. Contamination with that infection harms the human body 's
insusceptible (safeguard) framework and permits life–undermining diseases to create. HIV has no known cure or antibody for counteractive action.
Accessible therapeutic learning shows that transmission of HIV is basically through sexual contact or offering intravenous medication gear to somebody
who has a HIV disease. It additionally can be spread from a contaminated mother to her child some time recently, or amid, conveyance and through
bosom nourishing. HIV can 't be transmitted through easygoing contact, for example, sharing nourishment or beverage, touching surfaces, shaking
hands, dry kissing, or cooperating. HIV can 't be transmitted by mosquitoes or different bugs.
Regardless of the possibility that there are no side effects, a HIV–contaminated individual can transmit HIV to a sexual accomplice or to a
needle–sharing accomplice.
As a result of the reality of the HIV/AIDS issue, the University of Alabama at Birmingham has set up this strategy which concentrates on counteractive
action (through point by point instruction of understudies, workforce, and staff) and on the humane consideration of individuals with HIV

HIV antibodies can be detected during the acute phase of the infection, generally between 1 and 3 months, however, over time the immune response to
the infection will prove ineffective, as seen by figure 3, where the virus–specific antibodies have little to no effect on virus infected cells, and are only
effective on the virus particle itself. It can take up to 6 months for the host to be able to produce significant antibody amounts, and over time, the
immune response is weakened by the destruction of memory T cells, namely, CD4 and CCR5 cells. (The Biology Project, 2000) The antibody, IgG1 is

When the HIV virus is contracted, the antibody IgG1 becomes a key component in the humoral immune response, however, to produce enough
antibodies to fight infection can take anywhere between 1 and 6 months. In this time, the immune system is being weakened by the virus as the
destruction of T cells (CD4 cells) takes place. The Bubonic Plague pathogen, however, works differently and more effectively to shut down the immune
system quickly, essentially blocking a targeted immune response to the bacteria. Y.pestis injects the outer cell membrane of the macrophages with the
YopJ toxin to shut down cellular communication pathways, as well as stopping cytokine production. In doing so, the bacterium is able to ultimately
stop and immune response to the pathogen all together. Despite this distinct difference in chemical effects on the host, the immune system is similarly

Individuals with HIV may not notice and/or realize their symptoms because they may not appear for up to 10 years (CDC, 2013). The symptoms
include rapid weight loss, recurring fever and/or profuse night sweats, extreme and unexplained tiredness, prolonged swelling of the lymph glands in
the armpits, groin, or neck, and/or diarrhea that lasts for more than a week.
Within the United States, over 1.2 million people are living with HIV infection and about 13% of them are unaware of their infection. Additionally, it
is estimated that 50,000 new HIV infections are developing each year (CDC,2013). In the year 2013, about 47,352 people were newly diagnosed with

There is no cure for HIV; some HIV positive people viral loads can be down due to a combination of medicines and a healthy diet. Or seropositive
people could have some sort of a mutation. One example is where they over produce T helper cells (8).
The term AIDS applies to the most advanced stages of the HIV infection; Human immunodeficiency virus (HIV) and the disease it causes, acquired
immunodeficiency syndrome (AIDS). Acquired means you can get infected; Immune Deficiency means a weakness in the body's system that fights
diseases. Syndrome means a group of health problems that make up a disease (1). Killing or damaging T helper cells of the body's immune system, HIV
progressively destroys the body's ability to fight infections (1).
HIV is found in specific human body fluids. If any of those fluids enter your body, you can become infected with HIV. Common ways HIV is spread
is by having unprotected sex with an infected partner. The virus can enter the body through the lining of the vagina, vulva, penis, rectum, or mouth
during sex. Also, HIV commonly is spread within injection drug users by the sharing of needles or syringes contaminated with very small quantities
of blood from someone infected with the virus. Women can pass on the virus to their babies during pregnancy or birth. HIV can also be spread to
babies through the breast milk of mothers infected with the virus. Having a sexually transmitted disease such as Syphilis, Genital Herpes, Chlamydia, or

How to address the HIV/AIDS pandemic/ Intervention programs
Sex education
Sex education should be provided to all, especially the young generation so that they get to learn about ways of preventing them and reduce chances of
them contracting the disease. By giving them sex education, it enables them to take care of their bodies.
Peer counseling
This is also another method of preventing the likelihood for the spread of HIV/AIDS. This one helps to withdraw negative peer pressure, which may
mislead and lead others to carry out irresponsible sexual behavior
Adoption of safe sex practices It's advisable for people to practice safe sex. This will lead to prevention of the exchange of body and virginal fluids and
this increases chances of getting infections. Research has it that oral sex is much less risky than anal or vaginal sex (Balmer, 1993). Anal sex is the
most risky type of sex for the spread of HIV
Sexual abstinence Abstinence is the best method in which one can prevent the spread of a disease. Here the married couples are advised to remain
faithful in their relationships and for the unmarried people to abstain from sexual activities until marriage.

25. Simian Immunodeficiency Virus
According to the Center for Disease Control and Prevention, HIV is a virus spread through body fluids that affect specific cells of the immune
system, called CD4 cells, or T cells (CDC, 2014). These CD4 or T cells serve as a defense mechanism, which fight off infections and diseases. Once
this occurs, HIV leads to AIDS. Scientist identified a type of Chimpanzee in West Africa as the source of HIV infection in humans, it is believed to be
called simian immunodeficiency virus (SIV) (CDC, 2014). The virus was most likely transmitted to humans and mutated into HIV when humans
hunted these chimpanzees for meat and came into contact with their infected blood (CDC, 2014). Studies show that HIV may have jumped from apes

Within the first 2–4 weeks after having the infection, people experience flu like symptoms, which is called acute retroviral syndrome (ARS) and it
is the body's natural response to the HIV infection (Aids, 2013). Symptoms can include: fever (the most common symptom), swollen glands, sore
throat, rash, fatigue, muscle and joint aches and pains, and headaches. These symptoms can last anywhere from a few days to several weeks (Aids,
2013). It has been found that many people who are infected with HIV do not have any symptoms for 10 years or more (Aids, 2013). During the
clinical latency stage, people who are infected with HIV experience no HIV related symptoms or only mild ones, however, it is important to
remember that people in this stage are still able to transmit HIV to others. Last but not least, for those who have HIV infection and are not taking

27. Hiv And Its Effects On Acute Infection
HIV–1 establishes a reservoir in lymphoid tissue during acute infection that is the site of virus production from infected cells, storage in immune
complexes on the surface of the follicular dendritic cell (FDC) network, and persistence in a pool of latently infected resting memory CD4+ T cells
1–8. While combinations of antiretroviral drugs can suppress viral replication and reduce viral RNA to undetectable levels in plasma, virus production
from this reservoir of latently infected cells rekindles HIV–1 infection if drug treatment is stopped 9. The elimination or inactivation of latently infected
cells in reservoirs that give the virus safe haven from antiretroviral drugs or immune attack is key to bring about a cure.

Under these conditions, virus might continue to evolve in a small sanctuary site within the reservoir of cells in lymph nodes and remain undetectable in
blood depending on as yet unknown trafficking relationships between the two compartments. Here, we tracked the evolution of HIV–1 and inferred the
dispersal patterns among discrete anatomic compartments in time–resolved phylogenies. With a model of within–host infection dynamics, which
encodes drug–dependent viral fitness and site–dependent evolutionary pressures, we show that, in patients with undetectable levels of virus in their
blood, low amounts of viral replication can occur in a sanctuary site with suboptimal drug concentrations that do not breed drug–resistant strains.
We applied massively parallel sequencing to HIV–1 provirus populations in cells from blood and lymph nodes collected at three separate times (day 0,

28. Epidemiology Paper
Epidemiology:
HIV is known to be transmitted through blood products, semen and vaginal secretions, making the transmission of HIV infection most commonly
through sexual contact and IV drug use. HIV can enter the body through contact with the bloodstream or by passing through delicate mucous
membranes, such as inside the vagina, rectum or urethra (The Centers for Disease Control and Prevention: HIV/AIDS, 2015). The transmission routes
for HIV make unprotected sexual intercourse with an infected partner the number one reason for why HIV is on the rise. Often times this transmission
route is the most dangerous, because those that are affected with the HIV infection do not know they have it unless they have been tested by their
health care provider.
The modes of transmission of HIV are very similar to those of hepatitis B and hepatitis C, in particular with respect to parenteral, vertical and sexual
transmission. Even though certain sexual practices are dodgier than others, with respect to anal intercourse and oral sex, it is difficult to justify the
risk of acquiring HIV through these practices themselves. As many people who are infected with HIV engage in multiple practices of sexual
intercourse with multiple partners, it is difficult to pinpoint the direct route of transmission in which the person acquired HIV. It has been estimated
that the risk for acquiring HIV is from receptive anal intercourse is between 1:100 and 1:30 and insertive anal intercourse is 1:1000, while

This discovery allowed scientist to conclude that HIV was created through a genetic mutation of the SIV. How the SIV migrated into a human host will
never be known but a common theory was that a man hunted and ate a chimpanzee, allowing the SIV in the chimpanzee to enter into the human's body.
Another acceptable theory was that the chimpanzee's blood may have seeped into the hunters wound during his hunt.
Aside from getting HIV from chimpanzees, HIV can also be obtained through unprotected sex, using an unsterilized needle, childbirth, breastfeeding,
or blood to blood contact. Once inside the bloodstream the HIV virus will infect certain white blood cells, primarily the CD4 T cells. The HIV's
outer envelope consist of glycoproteins that mutates frequently, causing the CD4 T cells to not recognize the virus as a threat (_). The CD4 T cells
will then allow the virus to bind its GP120 onto the Help T cell receptor/coreceptor, also known as CCR5. After binding to its host cell the virus
transmembrane (GP41) will then pull the virus closer to the host cell, ultimately allowing the virus to fuse into the host cell. Once fused, the virus
nucleocapsid will then enter into the cell and release two viral RNA strands and three replication enzymes: reverse transcriptase, integrase, and

Stages of HIV HIV is categorized into three possible stages of disease. Stage 1 is considered the Acute HIV infection stage. In 2 to 4 weeks following
exposure to the infection, individuals have reported experiencing flu–type symptoms which last at a varying rate and individuals are extremely
contagious without knowing they are infected (CDC, 2016b). Stage 2 is known as HIV inactivity or dormancy (CDC, 2016b). This is a phase that is
typically asymptomatic, where there is still a live, active virus, but it is reproducing itself at a significantly low level (CDC, 2016b). With proper
medication intervention, this stage can last for several decades, without it, they become more symptomatic (CDC, 2016b). As an individual's viral load
increases, they become more symptomatic, and their risk of infecting others also increases significantly. These individuals are at risk of moving into
stage 3 known as Acquired Immunodeficiency Syndrome (AIDS); requires a CD4 cell count less than 200 cells/mm or specific opportunistic illness
(CDC, 2016b).

2.Females who use drugs may be raped, get infected by HIV–AIDS or get pregnant. Females who use drugs may not think of the consequences of their
actions. They may do things that they don't usually do like going to the male's bathroom or agreeing to be with a male stranger. Some males may take
sexual advances and that is when rape happens.
3.Drug–dependents may trade sex for drugs. There are drug dependents who cannot support their addiction, therefore, will sell their body as a way to

mortality in Nigeria are lower respiratory infections. Lower respiratory infections (LRIs) are commonly caused by viral infections. The most common
lower respiratory infections are bronchitis, pneumonia, and the chronic cough. In Nigeria, the contraction of LRIs can occur due to a poor standard of

42. HIV Infection Essay
Gastrointestinal infections seen with HIV infection may occur from such parasitic organisms as Entamoeba histolytica, Entamoeba coli, Giardia
lamblia, Cryptosporidium sp,
Microsporidium sp, and Cytoisospora (formerly Isospora) belli. Only Cryptosporidium and
Cytoisospora are part of definitional criteria for AIDS, though one or more of these agents may be identified in the GI tract by stool examination at
some point in the course of AIDS.[419]
Cryptosporidium is far more frequently identified than Microsporidium or Cytoisospora, at least in developed nations, while the others are more
sporadic in occurrence. In the U.S. less than 5% of HIV infected persons develop cryptosporidiosis, with an increased risk for infection when the

There are no specific gross pathologic features of cryptosporidiosis, and infection is usually unaccompanied by inflammation, hemorrhage, or
ulceration. Diagnosis is usually made from stool specimen examination, either by microscopy or aided by PCR analysis. After ingesting infective
oocysts, there is formation of sporozoites that attach to intestinal epithelium to trigger elongation of microvilli that enclose the sporozoite within a
vacuole. There is asexual multiplication of the organisms in host intestinal epithelial cells within a vacuole so that the organisms are intracellular but
extra cytoplasmic located on the brush border. These sporozoites become merozoites that invade adjacent cells. Gametogeny follows next, leading to
production of oocysts that are either thin–walled and auto infective or thick–walled and passed in feces to become infective to others. More thin–walled
oocysts are present in immunocompromised hosts, leading to the persistence with greater severity of the disease. The incubation period is 2 to 14
days.[432,536,536,539
The cryptosporidia appear histologically as quite small 2 Ојm uniform rounded shapes; they develop outside of human cells but within a vacuole
derived from the host cell. Thus, in tissue sections stained with hematoxylin–eosin, these organisms are small pale blue dots found lined along the
mucosal brush border of the intestine.
