Two different types of HIV have been identified in humans: HIV-1 and HIV-2.Both types of HIV are acquired sexually. Both cause AIDS.HIV-1 appears to be more virulent that HIV 2.HIV-1 is most commonly found in the United States, Canada and Europe. HIV-2 has been primarily found in Africa.Other differences between HIV-1 and HIV-2 are:HIV-2 appears to be less easily transmittedThose with HIV-2 are less infectious early in the course of the infectionThe period between initial infection and illness is longer in HIV-2, meaning that those with HIV-2 will show slower deterioration of the immune systemAs the disease advances, HIV-2 infectiousness seems to increaseHIV-2 seems to be less transmissible from an infected mother to her child
It is a Virus, infact the V in HIV stands for Virus
Hiv
It is a virus.
HIV is too small to see with a light microscope. You will need an electron microscope.
Worldwide it is estimated that approxiately 34 million people in the world have HIV. There is a concentration of the virus in sub-saharan africa, although all continents are affected. In some communities up to 50% may be HIV positive.
The movie, Invisible, is about a gay couple who supposedly practiced unsafe sex. One partner gave the other man HIV. The movie has mixed reviews and may have given inaccurate inflated statistics, according to one review.
As of 2013, AIDS and HIV continue to be a problem for both gay communities and straight communites alike.
The organization Invisible Children continues to focus on advocacy, awareness, and rehabilitation programs for communities affected by conflict in East and Central Africa. They have shifted their approach over the years but remain dedicated to supporting peace and development initiatives in the region.
HIV-1 is by far the more virulent of the two species of HIV.Because HIV-1 is more easily transmitted, it also spreads more readily and therefore accounts for the vast majority of global HIV infections.HIV-2, because it is much less transmittable, is largely confined to West Africa (where it is thought to have originated) and to West African migrant communities in Europe.HIV-1 also mutates more efficiently that HIV-2 and generally progesses to AIDS at a significantly faster rate than HIV-2 does.

It is better to be HIV negative than HIV positive. An HIV positive person is infected with HIV.
The Invisible Man.
HIV-positive means you are infected with the human immunodeficiency virus. HIV-negative means that you are not infected with the HIV.
You are not as invisible as you think you are. Her amorous intentions were invisible to me.
