A blood test can determine whether or not a person is infected with HIV. The most commonly used test detects antibodies (disease-fighting proteins) against HIV. It may take as long as three to six months for HIV antibodies to reach levels that are measurable in standard blood tests.

The only way to tell you have HIV is be tested for the virus. You cannot rely on symptoms to tell if you or someone you know is infected. The symptoms of HIV are similar to many other illnesses and many people have no symptoms at all. The symptoms of AIDS are also similar to other diseases. If a person is infected with HIV, the only way to tell if they have progressed to AIDS is to be diagnosed by a doctor using the CDC defined criteria.

Studies of families of HIV-infected people have found that HIV is not spread through sharing utensils, towels, bedding, or toilet facilities. Behaviors that increase the likelihood of contact with blood from an HIV-infected person, such as sharing a razor or toothbrush, should be avoided.

Only with a blood test. A person can be HIV infected for many years while looking and feeling healthy, with no signs at all of being sick.

A person with HIV can live for many years without showing any outward signs of illness. The majority of persons infected with HIV do not know they have the virus. However, they can infect others. Persons who have been infected with HIV will eventually develop AIDS.

Using such facilities does not put a person at risk for HIV infection. Only activities that cause intimate contact with blood, vaginal secretions, semen, pre-ejaculation fluid, or breast milk of an HIV-infected person can transmit HIV.

The only way to determine for sure whether you are infected is to be tested for HIV infection. You cannot rely on symptoms to know whether or not you are infected with HIV.

Most of time, there is no way of telling if someone has HIV by looking at them. However, if an infected person is not cared for and becomes sick, they may look small and thin and have skin diseases or other illnesses.

You do have a responsibility to let past and current needle-sharing and/or sexual partners that they were exposed to HIV as soon as possible since they should be tested. For many people, telling partners, friends and family is hard. Sometimes an HIV diagnosis brings secrets - about sexual partners, sexual activity or chemical dependency - out into the open.

Globally, 45 percent of adults living with HIV/AIDS are women. By region, this percentage varies considerably, from 57% in Sub-Saharan Africa, to 28% in East Asia and the Pacific. In 2004, 17.6 million women were living with HIV/AIDS worldwide.

Infection with HIV in this way is rare. There have only been a couple of documented cases of HIV transmission resulting from biting. In these particular cases, severe tissue tearing and damage were reported in addition to the presence of blood. REF: HOW AIDS CAN BE TRANSMITTED

People infected with HIV may take 7-10 years to develop AIDS. In developing countries like India, the progression to AIDS may be sooner because of malnutrition and a poorer state of health.

A person living with HIV (medically known as an HIV positive person) is one who has virus in his/her body. Such a person, remains infected and is presumed infective for the rest of his/her life. However, s/he will appear to be perfectly normal and healthy and asymptomatic for many years. An asymptomatic HIV infected person does not have Acquired Immunodeficiency Syndrome (AIDS).
