Test for or infection with human immunodeficiency virus hiv?

Test for or infection with human immunodeficiency virus hiv?

HIV testing: There are several HIV tests. We usually check what is called an elisa blood/oral test. It's very sensitive & specific but misses early, early infection (<15-20 days). In us we confirm a + elisa w/a test called a western blot (looks for HIV specific proteins). Other countries just use elisa x2. For acute HIV infection we measure viral RNA in blood. Can be falsely + so needs expert evaluation. ...Read more

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 the human immunodeficiency virus (hiv) transmitted?

How is the human immunodeficiency virus (hiv) transmitted?

Sharing body fluids: Hiv is a sexually transmitted infection. It can also be spread by contact with infected blood, or from mother to child during pregnancy, childbirth or breast-feeding. It can take years before HIV weakens the immune system to the point that the patient has aids. There is no cure for hiv/aids, but there are medications that can dramatically slow the progression of the disease. ...Read more

How is the human immunodeficiency virus (hiv) transmitted to heterosexuals?

How is the human immunodeficiency virus (hiv) transmitted to heterosexuals?

Same as heterosex: Hiv is transmitted by the virus present in body secretions deposited onto areas of either mucous membranes (rectal mucosa, oral mucosa or tonsils) where there are receptor sites to which the virus attaches. There are some forms of sexual activity in which individuals are more prone to bleeding, in which case these bleeding sites present a rapid route for viral entry. ...Read more

What type of cell does herpesviridae (herpesvirus) infect in humans?

What type of cell does herpesviridae (herpesvirus) infect in humans?

Skin cells: The herpes virus comes in 2 types: herpes simplex (hsv) 1&2. Antibodies (igg) to both viruses can be tested to see if you have lasting immunity and (igm) short-term antibodies check to see if you have had a recent infection. Unfortunately the igg levels can not tell how long ago you were exposed. Also herpes 1 & 2 viruses can cause either oral or genital herpes. Hope that helps. ...Read more

Explan why one human immunodeficiency virus test cannot definitely diagnose hiv?

Good question: The HIV test to which you refer is an elisa assay which is quite sensitive but not as specific as the confirmatory western blot. These measure the presence of antibodies to the HIV and these may take from 2 wks to several months to develop. If you run the test before the antibodies have appeared, it will be negative, only to change to positive once antibody formation has occurred. ...Read more

Other high risk activities include sharing needles for intravenous drug use with infected individuals and having unprotected receptive anal intercourse with an HIV infected person. ...Read more

Can hepatitis virus infection interfere the progression of HIV disease?

Can hepatitis virus infection interfere the progression of HIV disease?

Yes: Co infection with hepatitis b or hepatitis c ( that is having HIV and either of the above) is documented to generally result in further progression of both diseases. Therefore, patients with either illnesses must be screened to rule out co infection... Treatment is encouraged for both viral illnesses. New treatments are available for hepatitis c. ...Read more

The symptoms of the aids virus infection?

Difficult to say: It is difficult to say exactly what are the common symptoms in someone with aids. Some people may have absolutely no symptoms at the time of diagnosis. Typical common symptoms may be very nonspecific, such as fever, weight loss, cough, or rash. As you can tell, these may also represent a typical cold or flu. Thus, the general recommendation is if you are concerned about hiv/aids, get tested. ...Read more

This virus mutates continuously and the form to which it mutates which is best capable of surviving under the circumstances is the one which will be reproduced and multiply within infected cells. Unless of course you are a creationist. ...Read more

Many and few.: At the outset the patient infected may not even be aware of the presence of the virus, and this can persist until the immune system is badly damaged, and secondary infections or cancers occur (8-12 yrs). Sometimes, acute HIV syndrome will present as a mononucleosis-type illness with multiple symptoms. Best thing to do is get checked and tested if you feel you have been exposed. ...Read more

Human immunodeficiency virus--does it lead to any diseases besides aids?

Yes: In addition to causing aids, we now know that HIV also increases chronic inflammation and immune activation, which can increase the risk of complications like coronary heart disease, malignancies, decreased bone density, and cognitive dyfunction. There is a lot of interest now in HIV as a cause of earlier complications of the aging process. ...Read more

Is there any statistics for HIV1/HIV2 ratio in all HIV world?i.e %80 of HIV infected people carry HIV1?

HIV: HIV 1 is more prevalent in the US and Europe and HIV 2 are more prevalent in Africa. But there are no statistics because a big portion of the population does not even know their HIV status. HIV is now increasing in the 16 years old to 25 years old, despite education most people are having sex without protection and also there is an increase in multiple sex partners.

Cellular immunity: These are cells that work as part of the cellular immune system, fighting certain fungal (e.g. Cryptococcus), viral (e.g. Herpesviruses), parastic (e.g. Toxoplasma), and bacterial (e.g. Tuberulosis) infections. The cellular immune system also helps to prevent certain cancers, such as lymphomas. ...Read more

Human immunodeficiency virus--can it mutate?

Human immunodeficiency virus--can it mutate?

Yes: Hiv mutates in response to HIV therapy. If you're being treated without a complete response (partial suppression), the virus can mutate so it can replicate in the presence of the drugs. This usually happens in people who don't take their medications properly. They can then transmit the mutant virus to others. Spontaneous mutation (mutation independent of therapy) has not been a big problem. ...Read more

If a cure were to be discovered for human immunodeficiency virus, what would it do?

HOPEFULLY GO AWAY: Viruses are not cognitive creatures. If we were to devise some means of eradicating the infection they would either mutate to a form which would again produce disease, or disappear or become a benign commensal. Philosophically, it has been said that infections are a result of two biological beings coming in contact with each other and yet not finding full compatibility, which hopefully changes. ...Read more
