How is the human immunodeficiency virus (hiv) transmitted easiest?

Blood. Tainted blood transfusions are the easiest way to become infected with hiv. In the developed world, all blood is screened for HIV and blood transfusions are safe. 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.

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.

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.

Could I obtain the human immunodeficiency virus (hiv) from eating after someone that has it?

No. Hiv is not transmissible by sharing food or utensils. Hiv is spread by directly sharing body fluids such as semen or blood. This most commonly happens during sexual intercourse and / or with needle sharing. Always use a condom and spermicidal lubricant with sex and never re-use a needle that has been used by another person. Be safe.
No. You can get HIV from blood or bodily fluid transfusions or organ transplant or sexually intercourse. Casual contact such as food sharing or light touch or kiss has not lead to HIV transmission.

The human immunodeficiency virus (hiv) infects helper t cells. What is the role of these cells?

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.

How did human immunodeficiency virus (hiv) evolve?

Evolution. It came from a simian precursor transmitted to humans by one of several mechanisms. 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.

How has human immunodeficiency virus (hiv) evolved since late 1970s?

Probably not. The virus itself probably hasn't evolved much. What has evolved is our ability to treat it. Resistance mutations occur, but this sort of evolution affects individuals and sometimes the people they infect. It has not resulted in global evoluation of the virus.

Test for or infection with human immunodeficiency virus hiv?

HIV infection. I am unsure what you are really asking so if I missed it please rephrase the question. There are two ways to test for HIV infection. One, the most common test, looks for antibodies produced by the infected human's immune system. Antibodies can take up to six months to be detectable after an infection...So a long time to wait to get an accurate answer. Then there is the viral dna or RNA test.
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.

How to know if I have hiv's (human immunodeficiency virus)?

Get tested. The only way to know if you have HIV is to get tested for hiv. Please visit with a clinic or doctor and have testing performed. The clinic or doctor will explain the results and be able to answer questions. To decrease risk, always use clean (single use) needles for injection drugs and always have 'safe' sex with a condom and spermicidal lubricant. Be well.

Can you tell me if I could possibly have HIV (human immunodeficiency virus)?

HIV. Hiv can be transmitted via anal ; oral sex, blood transfusion, use of contaminated needles, breastfeeding ; during pregnancy ; delivery. Do you engage in behaviors that put you at risk?
