What is HIV/AIDS? HIV means Humanimmunodeficiency virus while AIDS means Acquired ImmunodeficiencySyndrome –It’s a disease of the human immune system caused by the human http://jonnyboi.pininc.track.clic immunodeficiency virus ksure.com http://jonnyboi.comcheat.track.

ANALYSIS OF HIVWhat Is HIV?To understand what HIV is, let’s break it down:H – Human – This particular virus can only infect human beings.I – Immunodeficiency – HIV weakens your immune system by destroying important cells that fight disease and infection. A "deficient" immune system cant protect you.V – Virus – A virus can only reproduce itself by taking over a cell in the body of its host.Human Immunodeficiency Virus is a lot like other Viruses, but the difference is that, your immune system can clear most viruses out of your body. But can not get rid of HIV. Scientists are still trying to figure out why. http://jonnyboi.pininc.track.clicksure.com http://jonnyboi.comcheat.track.clicksure.com http://waystomakeeasymoneyonline.blogspot.com
ANALYSIS OF AIDSWhat Is AIDS?To understand what AIDS is, let’s break it down:A – Acquired – AIDS is not something you inherit from your parents. You acquire AIDS after birth.I – Immuno – Your bodys immune system includes all the organs and cells that work to fight off infection or disease.D – Deficiency – You get AIDS when your immune system is "deficient," or isnt working the way it should.S – Syndrome – A syndrome is a collection of symptoms and signs of disease. AIDS is a syndrome, rather than a single disease, because it is a complex illness with a wide range of complications and symptoms.Acquired Immunodeficiency Syndrome is the final stage of HIV infection. People at this stage of HIV disease have badly damaged immune systems, which put them at risk for opportunistic infections (OIs).You will be diagnosed with AIDS if you have one or more specific OIs, certain cancers, or a very low number of CD4 cells. If you have AIDS, you will need medical intervention and treatment to prevent death.
Where Did HIV Come From?Scientists believe HIV came from a particularkind of chimpanzee in Western Africa. Humansprobably came in contact with HIV when theyhunted and ate infected animals. Recent studiesindicate that HIV may have jumped frommonkeys to humans as far back as the late1800s.http://jonnyboi.pininc.track.clicksure.comhttp://jonnyboi.comcheat.track.clicksure.comhttp://waystomakeeasymoneyonline.blogspot.com
How Do You Get HIV?• HIV is found in specific human body fluids. If any of those fluids enter your body, you can become infected with HIV.
Which Body Fluids Contain HIV? HIV lives and reproduces in blood and other body fluids. We know that the following fluids can contain high levels of HIV:• Blood• Semen (cum)• Pre-seminal fluid (pre-cum)• Breast milk• Vaginal fluids• Rectal (anal) mucous• Other body fluids and waste products—like feces, nasal fluid, saliva, sweat, tears, urine, or vomit—don’t contain enough HIV to infect you, unless they have blood mixed in them and you have significant and direct contact with them. Healthcare workers may be exposed to some other body fluids with high concentrations of HIV, including:• Amniotic fluid• Cerebrospinal fluid• Synovial fluid
How Is HIV Transmitted Through Body Fluids? HIV is transmitted through body fluids in very specific ways:• During sexual contact: When you have anal, oral, or vaginal sex with a partner, you will usually have contact with your partner’s body fluids. If your partner has HIV, those body fluids can deliver the virus into your bloodstream through microscopic breaks or rips in the delicate linings of your vagina, vulva, penis, rectum, or mouth. Rips in these areas are very common and mostly unnoticeable. HIV can also enter through open sores, like those caused by herpes or syphilis, if infected body fluids get in them. You need to know that it’s much easier to get HIV (or to give it to someone else), if you have a sexually transmitted disease (STD).• During pregnancy, childbirth, or breastfeeding: Babies have constant contact with their mother’s body fluids-including amniotic fluid and blood-throughout pregnancy and childbirth. After birth, infants can get HIV from drinking infected breast milk.• As a result of injection drug use: Injecting drugs puts you in contact with blood-your own and others, if you share needles and “works”. Needles or drugs that are contaminated with HIV-infected blood can deliver the virus directly into your body.• As a result of occupational exposure: Healthcare workers have the greatest risk for this type of HIV transmission. If you work in a healthcare setting, you can come into contact with infected blood or other fluids through needle sticks or cuts.• As a result of a blood transfusion with infected blood or an organ transplant from an infected donor: Screening requirements make both of these forms of HIV transmission very rare in the United States.
Ways through which HIV/AIDS is not contactedHIV cannot reproduce outside the human body. It is not spread by:• Air or drinking water from the same pot with an infected person.• Insects: including mosquitoes. Studies conducted by researchers have shown no evidence of HIV transmission from insects.• Saliva, tears, or sweat. There is no documented case of HIV being transmitted by spitting.• Casual contact like shaking hands or sharing dishes.• Closed-mouth or ―social‖ kissing.
Symptoms and Signs of HIVWithin weeks of infection, many people will develop the varied symptoms of primary or acute infection which typically have been described as a "mononucleosis" or "influenza" like illness but can range from minimal fever, aches, and pains to very severe symptoms.The most common symptoms of primary HIV infection are:• fever,• aching muscles and joints,• sore throat and• swollen glands (lymph nodes) in the neck.• Ulcers in the mouth http://jonnyboi.pininc.track.clicksure.com http://jonnyboi.comcheat.track.clicksure.com http://waystomakeeasymoneyonline.blogspot.com
How Do You Get AIDS?AIDS is the late stage of HIV infection, when aperson’s immune system is severely damagedand has difficulty fighting diseases and certaincancers. Before the development of certainmedications, people with HIV could progress toAIDS in just a few years. Currently, people canlive much longer - even decades - with HIVbefore they develop AIDS. This is because of―highly active‖ combinations of medications thatwere introduced in the mid 1990s.
AIDS: Signs and SymptomsWhen HIV infection progresses to AIDS, manypeople begin to suffer from fatigue, diarrhea,nausea, vomiting, fever, chills, night sweats, andeven wasting syndrome at late stages. Many ofthe signs and symptoms of AIDS come fromopportunistic infections which occur in patientswith a damaged immune system. http://jonnyboi.pininc.track.clicksure.com http://jonnyboi.comcheat.track.clicksure.com http://waystomakeeasymoneyonline.blogspot.com
The Global HIV/AIDS Crisis Today• HIV, the virus that causes AIDS, has become one of the world’s most serious health and development challenges:• 33.4 million are currently living with HIV/AIDS.• More than 25 million people have died of AIDS worldwide since the first cases were reported in 1981.• In 2008, 2 million people died due to HIV/AIDS, and another 2.7 million were newly infected.• While cases have been reported in all regions of the world, almost all those living with HIV (97%) reside in low- and middle-income countries, particularly in sub-Saharan Africa.• According to the World Health Organization (WHO), most people living with HIV or at risk for HIV do not have access to prevention, care, and treatment, and there is still no cure.
