Knowledge, Attitude and Practice of Migrant Workers’ Wives on HIVAIDS in Bang...Md. Tarek Hossain
In Bangladesh, the targets under MDG-6 are to halt the spread of HIV/AIDS, malaria and other diseases by 2015 and reverse the spread of the diseases. The increasing trend of HIV/AIDS positively indicates that country is on the brink of a nationwide crisis. Mobility is a key structural factor that has been linked to increased HIV incidence and vulnerability globally. Bangladeshi migrant workers suffer problems found among other internal and international migrant groups including socioeconomic and power inequalities, limited social capital, loneliness, and coping with different cultural norms relating to sex. HIV transmission from international migrant workers who have returned and are HIV positive has been mostly restricted to their spouses, although the degree of spousal transmission and couples in which one person is HIV positive and putting the other at high risk has not been evaluated methodically in Bangladesh. Given the large numbers of people on the move, ensuring the rights and access to HIV prevention, treatment and care and support services for the wives of these migrant workers is a crucial component of an effective regional response to HIV. Therefore, it is important to analyze the knowledge, attitude and practice level of these groups of women. Therefore, the present study aims to analyze the knowledge, attitude and practice of wives of the emigrant workers of Bangladesh and factors that may influence their health decisions. Seven
(7) districts from seven (7) administrative divisions of the country were selected purposively as the study area. The study areas include Tangail (Dhaka division), Comilla (Chittagong division), Moulovibazar (Sylhet division), Meherpur (Khulna division), Dinajpur (Rangpur division), Barisal (Barisal division) and Serajganj (Rajshahi division). Women at their reproductive age from selected households of these seven districts, whose heads are/used to be a migrant worker, was the study subject. Respondents also include health service professionals from the study areas. The general knowledge/ perception, attitudes, and practices were assessed through qualitative study method while a quantitative socio economic survey was also done to attain information related to respondents’ age, education, income and expenditure. The tools include in-depth interview (II), focus group discussion (FGD) and key informant interview (KII). In total,
70 KIIs and 7 FGDs with 63 women participants were done while a short survey of the socioeconomic status of all 133 women was conducted through structured questionnaire.

This slide discusses about epidimiology of HIV its National and international response HIV:- Human Immuno deficiency Virus (retro-virus)
HIV attacks body immune system and reduces the count of CD4 cells (T cells) in human body making the person more likely to get life-threating opportunistic infections.
AIDS:- Acquired Immune Deficiency Syndrome, is a set of symptoms and illness which develops at the final stage of HIV infection.
There is currently no effective cure for HIV. Once people get HIV, they have it for life. But with proper medical care, HIV can be controlled and who get effective treatment can live long, healthy lives and protect their partners.
As far back as the late 1800s, HIV may have spread from chimpanzees to humans.
Simian immunodeficiency virus (SIV) is a lentivirus (genus of retrovirus) that infect more than 36 different nonhuman primate species in sub-Saharan Africa.
In June 1981, the first cases of AIDS reported from Los Angeles in five homosexual men.
In Nepal first case detected in 1988.
HIV (Human Immunodeficiency Virus) infects cells of the immune system and destroys or impairs their function.
Infection progressive deterioration of the immune system breaking down the body's ability to fight out infections & diseases by opportunistic bacteria, viruses and fungi.
AIDS (Acquired Immune Deficiency Syndrome) refers to the most advanced stages of HIV infection and a collection of signs and symptoms caused by more than 20 opportunistic infections or related cancers.
At the end of the session, the students shall be able to
Describe the HIV AIDS introduction, epidemiology of HIV AIDS, diagnosis of HIV AIDS, treatment of HIV AIDS and prevention control of HIV AIDS.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

34. •PrEP: Short for “pre-exposure prophylaxis,” PrEP is
an HIV prevention strategy in which HIV-negative
people take an oral pill once a day before coming
into contact with HIV to reduce their risk of HIV
infection. PrEP must be taken for at least 7 days to
reach optimal levels of protection against HIV.
•PEP: Short for “post-exposure prophylaxis,” PEP is
an HIV prevention strategy in which HIV-negative
people take anti-HIV medications after coming into
contact with HIV to reduce their risk of HIV infection.
PEP must be started within 72 hours after HIV
exposure.
35. What is emergency HIV treatment?
Post-exposure prophylaxis, or PEP, is another
name for emergency HIV treatment.
PEP is not a cure for HIV, it is a form of HIV prevention.
It is a short course of antiretroviral drugs that
stops exposure to HIV from becoming a life-long
infection. Taking PEP can cause side effects such as
nausea and fatigue. DO NOT stop taking PEP - talk to
your healthcare professional.
PEP must be taken as soon as possible to be
effective and no later than 72 hours after
exposure to HIV.
PEP must be taken at the same time every day for 4
weeks.
36. Who can get PEP?
Usually you should only take PEP if :
• it has not been longer than 72 hours since exposure
to HIV
● you are not already living with HIV
● a mucous membrane (including: eyes, mouth, vagina,
rectum) has had direct contact with.
● someone’s bodily fluid that might be infectious or an
open wound has had direct contact with someone’s
bodily fluid that might be infectious.
● the source of exposure is infected with HIV or their
HIV status is unknown.2
37. • PEP and HIV testing : It’s normal to feel anxious
about being infected with HIV. Don’t let being
worried stop you from getting an HIV test.
• If you took PEP - get tested 3 and 6 months
after potential exposure.
• If you didn’t take PEP - get tested 3 months
after potential exposure.
• PEP in pregnancy : Certain PEP drugs can be
taken during pregnancy.However,some drugs
should not be used for PEP if you are pregnant.
Speak to a healthcare professional about your
options.
38. HIGHLY ACTIVE ANTIRETROVIRAL
THERAPY (HAART)
Highly active antiretroviral therapy (HAART) for the chronic
suppression of HIV replication has been the major
accomplishment in HIV/AIDS medicine
Many patients are now in their second decade of treatment,
with levels of plasma HIV RNA below the limits of detection of
clinical assays
Many patients are now enjoying a life-style little encumbered
by symptoms or the side effects of medications, many of which
require only once daily administration
39. MAIN OBSTACLE TO HIV CURE
VIRUS LATENCY
The CD4 T cells (T helper cell) and other myeloid, such as bone-marrow-
derived, cells are the main targets of HIV infection. The Problem
is replication-competent HIV provirus can persist in resting CD4 T cells
and maybe in these other cells as well.
Accurately assess latent virus load, is technically difficult to do so
because Methods that measure integrated HIV virus DNA tend
to overestimate latency since they can't discriminate replication-defective
HIV DNA. Similar drawback attends methods that measure HIV RNA. While
the quantitative viral outgrowth assay (QVOA) is far better at measuring
frequency of truly latent, replication-competent provirus, it tends
to underestimate the size of the latent reservoir.
40. WHAT IS THE CURRENT STATE OF THE HIV CURE?
As of 2016, there is one confirmed case of HIV cure, that
of Timothy Ray Brown, one of two of The Berlin Patient. He
was diagnosed with HIV in 1995 while studying in Berlin,
Germany, in 2007 he underwent Hematopoietic stem cell
transplantation from a donor with a rare mutation, which is
homozygous meaning in both alleles. The mutation renders a
person resistant to HIV infection by disabling its entry into
susceptible cells that express CCR5 on their cell surface.
Timothy Ray Brown is considered completely
cured, sterile cure as in no longer harboring HIV in his body. He
is off of antiretroviral therapy (ART).
41. • Two Boston patients were also treated using stem cell
transplantation though not from CCR5-delta32
homozygous donors. However, they experienced relapse
.
• The VISCONTI cohort is a group of 14 French patients who
started ART within the first few weeks of getting HIV infected.
In remission now for 12 years and counting, they're
considered 'functionally' cured of HIV, i.e., continuing to
harbor HIV but no longer needing to take ART.
• The same group's also reported similar outcome for a
perinatally infected case treated from birth for at least
the first 5 years. This patient remained in remission
when re-examined at length at 18 years of age.

45. NUCLEO(T)SIDE REVERSE TRANSCRIPTASE
INHIBITORS (NRTIS)
•First agents available for HIV
Infection.
•Less potent than NNRTIs) and
pIs.
•Have a central role in ART.
•Have activity against HIV-1 and
HIV-2.

• Tipranavir,TPV
• First introduced in
1995
• Are an integral part
of treatment
• Exhibit activity

isolates of both HIV-
1 and HIV-2.
48. ENTRY INHIBITORS - CHEMOKINE
(CCR5) CO-RECEPTORANTAGONIST
• Maraviroc
• Binding of gp120 HIV surface protein to CD4 receptor induces a structural
change that revealsV3 loop of the protein.
• V3 loop then binds with a chemokine coreceptor (principally either CCR5 or
CXCR4),allowing gp41 to insert itself into the host cell and leading to fusion of
the cell membranes.
• Maraviroc selectively and reversibly binds CCR5 coreceptor,blockingV3 loop
interaction and inhibiting fusion of cellular membranes.
• As some viral strains may use an alternate co-receptor CXCR4 for entry,
• a tropism assay is necessary to confirm that patient’s virus only uses CCR5 for entry.
49. FUSION INHIBITORS
• Enfuvirtide,
• Act extracellularly to prevent fusion of HIV to CD4 or other target cell.
• Blocks second step in fusion pathway by binding to HR1 region of gp41.
• Does not allow HR1 and HR2 to fold properly,
• Thus preventing conformational change of gp41 required to complete final step in
fusion process
• Dose 90 mg SC bid
• Dose adjustments are not required in patients with renal insufficiency or mild-to-
moderate hepatic insufficiency
• ADRs Injection-site reactions (eg, pain,erythema, induration, nodules) diarrhea,
nausea,fatigue, hypersensitivity reactions, increased rate of bacterial pneumonia
50. INTEGRASE INHIBITORS (HIV
INTEGRASE STRANDTRANSFER
INHIBITORS)• HIV integrase
• Responsible for transport and attachment of proviral DNA to host-cell chromosomes,allowing
transcription of viral proteins and subsequent assembly of virus particles.
• Proviral integration involves 2 catalytic reactions:
• 3'-processing in host-cell cytoplasm to prepareproviral strandsfor attachment
• Strand transfer whereby proviral DNA is covalently linked to cellular DNA
• IIs Competitively inhibitstrand transfer reaction by binding metallic ions in active site.
• Raltegravir & Elvitegravir
• Dolutegravir
• Newest integrase inhibitor, is now in very advanced clinical trials, with approval
expected towards the end of 2013.
• once-a-day medication, can be taken separately.
• doesn't require a booster
• appears to work against virus that is resistant to raltegravir and/or elvitegravir.
52. TYPES OFTREATMENT FAILURE
• Virologic Failure: if viral load is not <400 copies/mL after 3mo
• Immunologic Failure:
• The CD4 cell count persistently falls below the baseline CD4 cell
count
• The CD4 cell count fails to increase by more than 25-50 cells/μL after
one year of treatment
• There is a > 50% decline in CD4 cell count from its highest level on
ART
• Clinical Failure:
• when the patient has a newAIDS-defining illness—i.e.,a newWHO stage
3 or 4 condition--after initiation of ART

58. HIV LATENCY
• Latently infected resting memory CD4+ T cells are the best
characterized latent reservoir for HIV-1.
• Less than 1 cell per 1,000,000 resting CD4+ T cells from
patients on HAART harbor latent HIV-1 provirus.
• Sequence of latent proviruses does not evolve, which
suggests no ongoing viral replication.
• Discontinuation of HAART allows viral relapse from latent
reservoir.
59. HIV LATENCY(CONT.)
• Patients successfully treated with HAART for longer than 10
years exhibit no appreciable decrease in the size of the latent
reservoir.
• The persistence of latently infected memory CD4+ T
lymphocytes precludes their elimination by HAART alone for
the lifetime of the patient.
• Other drug-insensitive reservoirs, including brain,
macrophages, and hematopoietic stem cells, may also exist.
• Latency is likely established and maintained by numerous
blocks at multiple steps in the HIV-1 replicative pathway,
which potentially complicates eradication strategies.

62. PRINCIPLES OF HIV DRUG RESISTANCE
• Results from changes (mutations) in genetic information in virus
• These changes occur whenever HIV is replicating
• Partial HIV suppression promotes resistance
• Resistance can be delayed by suppressing virus completely
• RT and protease are flexible (highly mutable)
• Resistance may fade but not disappear when a drug is stopped
• Some mutations allow certain viruses to resist effects of one or more
antiretroviral drugs
• Drug resistant virus usually grows faster and better than drug susceptible virus
• Drug resistant virus replaces drug susceptible virus in patient
63. 63
MINIMIZE EMERGENCE OFVIRAL
RESISTANCE
• Never prescribeARVs in absence of adherence counseling
and support
• Never prescribe monotherapy or dual therapy
• Ensure optimal serum drug concentrations
• Avoid drug interactions
• Diagnose and manage malabsorption
• IfARV medications are to be discontinued,stop all drugs at
same time
• Possible exception: NNRTI-based regimen
64. HAART is no panacea.
Current treatments must be maintained for life
with treatment interruption resulting in the rapid
rebound of replicating virus
Although drug resistance can emerge

• These changes occur whenever HIV is replicating
• Partial HIV suppression promotes resistance
• Resistance can be delayed by suppressing virus completely
• RT and protease are flexible (highly mutable)
• Resistance may fade but not disappear when a drug is stopped
• Some mutations allow certain viruses to resist effects of one or more antiretroviral
drugs
• Drug resistant virus usually grows faster and better than drug susceptible virus
• Drug resistant virus replaces drug susceptible virus in patient
66. RESISTANCETESTING
• Two types:
• Genotyping
Detects drug resistance mutations on virus genome that may make it
resistant to certain antiretrovirals
• Less expensive
• Can usually be completed in 1-2 weeks
• Phenotyping
Measure ability of viruses to grow in presence of various
concentrations of antiretroviral drugs
• More expensive
• Generally takes 2-3 weeks to complete
67. 67
Resistance Mutations
• For some drugs (NNRTIs and 3TC), a single mutation causes high-level
resistance.
• Resistance to these drugs occurs very quickly
• For other drugs (most NRTIs and PIs), many mutations must occur before
high-level resistance is observed.
• Resistance to these drugs occurs more slowly
Cross-Resistance
• Resistance to one drug can cause resistance to others of the same class
• NNRTI: complete cross-class resistance
• NRTI: partial cross-class resistance
• PI: partial cross-class resistance
• Partly overcome by ritonavir boosting

69. Despite the prolonged suppression of HIV
replication below the standard limits of detection for
patients on HAART, ongoing viremia can be detected
at levels of 1 to 50 copies per milliliter in the
majority of patients
The origin of this viremia has not been fully
characterized
75. WHY DO WE NEED VACCINE FOR HIVWHILE
INFECTION COULD BE CONTROLLED BY ARV
THERAPY ?
The suboptimal penetration of many antiretrovirals into the
central nervous system may also permit low levels of viral
replication and/or release from stable viral reservoirs,resulting
in neuropathology
There is already growing concern about increased rates of heart
disease,diabetes,liver disease,and many forms of cancer in aging
HIV-infected patients who are receiving treatment
the cost of HAART may be too much to sustain treatments on a
global scale,as millions are affected
76. AN IDEALVACCINE SHOULD BE ….
• Good immune response
• Both Cell Mediated Immunity and antibody responses.
• Immunity is long lived
• Single dose
• Safety
• Danger of reversion to virulence,or Severe disease in immunocomprised
• Stability
• Organisms in the vaccine must remain viable in order to infect and
replicate in the host
• Vaccine preparations are therefore very sensitive to adverse storage
conditions
• Maintenanceof the cold chain is very important.
• Expense
• Cheap to prepare
