Hiv (Definition)

Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which ...Read more

How is hiv/aids spread through dry blood I thought once it hits the air the virus dies So if someone touch the dried blood how can the virus be active?

How is hiv/aids spread through dry blood I thought once it hits the air the virus dies So if someone touch the dried blood how can the virus be active?

It cannot: The HIV virus is a very fragile virus and does not survive very long outside the body. Touching dried blood would not cause any risk for HIV infection. Although, other infections would be a concern so Always use appropriate personal protective equipment when cleaning up blood spills. Hope this was helpful. Dr. R ...Read more

Can HIV be spread at nail salon or makeup counter (try on makeup)? Lip gloss and nail polish are liquid, so virus not exposed to air. Chapped lips?

No risk, no worries: It is probable that nobody in the world ever caught HIV from something like this. If you don't have unprotected sex with partners at risk, and do not share drug injection equipment with other persons, you will never be at risk. Don't worry about any other kind of exposures. ...Read more

How can I contract the HIV virus?

Depends: Contracting HIV depends on multiple factors, including the type of exposure, how much virus is present from the hiv+ person, and host susceptibility, to name a few factors. Receiving an infected blood product is likely highest risk (though blood is screened rigorously). Risk of HIV sexual transmission depends on type of sexual behavior with anal sex being at higher risk than vaginal than oral sex. ...Read more

By what means the HIV virus come to be?

By what means the HIV virus come to be?

Natural evolution: Over time, all things evolve, including viruses. It is thought that an early form of HIV (called siv) started in monkeys and perhaps was transmitted to humans thru eating monkey meat. Viruses can mutate and evolve to become fitter over time ("survival of the fittest") and eventually came to be HIV as we know it today. In fact, HIV still continues to evolve and mutate to evade current HIV meds! ...Read more

For how long can the HIV virus live in open?

For how long can the HIV virus live in open?

No worries re: HIV: HIV -the virus that causes AIDS is acquired from sexual activity or injection drug use. You cannot get HIV infection from blood outside the body -since once it leaves the body it dies right away. This is obviously a good thing. For some viruses though, like Hepatitis B -they CAN survive outside the body. In India there's some Hep B there. There is a Hep B vaccine you can get. Hope you can be safe. ...Read more

How much time HIV virus can survive outside body?

How much time HIV virus can survive outside body?

It doesn't: HIV does not survive outside of the body. It is not ever caught by touching it or any other thing it is in or on. Millions of humans have now survived HIV free after taking care of infected humans. They have been bled upon, shat upon, vomited on, spit upon, peed upon. HIV is not caught by touching it or anything it has been in contact with. ...Read more

How is the HIV virus passed into the body tissues?

How is the HIV virus passed into the body tissues?

Various ways: The virus has reservoir cells where it remains inactive in tissues. These are macrophages and in the nervous system some neurons. It lives within lymphocytes (cd4 cells), and other cells which possess a receptor site to which it can attach and enter the cells. These cells then carry it into tissues. When the virus first enters the body it does so onto receptive surfaces. ...Read more

How long does HIV virus live outside a human being?

How long does HIV virus live outside a human being?

Not long: Viruses are critters which live inside cells and must have nutrients of a cell to remain alive. Most will die rapidly after leaving the body unless retained in body fluids within cells in those fluids. This takes varying times to resolve. As a general rule HIV is not transmittable casually. It needs direct tissue contact. Blood, shared needles, sex, organ transplant. ...Read more

What happens to people when they have the HIV virus?

Depends on treatment: Hiv is a serious health problem. The virus slowly destroys a person's cellular immune response and predisposes patients' to infections, certain malignant tumors, and dementia. Without treatment, usual life expectancy is 8 to 10 years. The good news is that with treatment, some people can live healthy and productive lives for many decades. Practice safe sex. Always use a latex condom. ...Read more

Can a dog transfer HIV virus to a child through a bite?

No a dog cannot: Dogs cannot get and carry the HIV virus in them. So dog bites are not likely source for transmission of hiv. However dog bites can sometimes get infected easily and therefore most children are started on antibiotics to prevent them from getting bacterial infections. ...Read more

How could the HIV virus come about (what was its origin)?

Green macaque: It is theorized that HIV has its origin in SIV, simian immunodeficiency virus, a virus that behaves much the same in the green macaque monkey from Central Africa. There is evidence dating back to the 1950s, possibly even earlier, that the virus mutated and passed to humans by consumption of the simian meat. ...Read more

How do retroviruses such as HIV differ from other types of viruses?

Rev transcriptase: "retro-" means backwards and the virus carries RNA which is translated backwards to dna by their own reverse transcriptase; the dna is then integrated into the host's genome. The "endogenous retroviruses" can even be passed from generation by infection the sperms / eggs. ...Read more

Is it true that an HIV rapid test can identify the virus within the first month?

No: Rapid tests are designed to test for antibody to HIV and generally take a few weeks to rarely a year to become positive. If you have any concern, get a HIV nucleic acid test and repeat it at six months after exposure.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex.
Get HPV vaccine. ...Read more

HIV: Retroviruses similar to HIV have been isolated from simians (monkeys, chimps, etc.) are called siv, and are the likely source of hiv. There are other retroviruses, and although could not cite specific examples, would be very surprised if they were not found in other animals. ...Read more
