HIV is a member of the genus Lentivirus, [15] part of the family Retroviridae. [16] Lentiviruses have many morphologies and biological properties in common. Many species are infected by lentiviruses, which are characteristically responsible for long-duration illnesses with a long incubation period. [17]
HIV can survive at room temperature outside the body for hours if dry (provided that initial concentrations are high), [31] and for weeks if wet (in used syringes/needles). [32] However, the amounts typically present in bodily fluids do not survive nearly as long outside the body—generally no more than a few minutes if dry. [23]
Within a specific kingdom ( Plantae, Animalia, Fungi etc) the localization of viruses colonizing the host can vary: Some human viruses, for example, HIV, colonizes only the immune system, while influenza viruses on the other hand can colonize either the upper respiratory tract or the lower respiratory tract depending on the type (human ...
Now millions of people take drugs known as antivirals that keep HIV from spreading in the body. Stopping those drugs lets the virus start multiplying in the body again, and it could become drug-resistant. HIV can rebound to detectable levels in people’s blood in just a few weeks, putting sexual partners at risk.
The human immunodeficiency virus (HIV) [8] [9] [10] is a retrovirus [11] that attacks the immune system.It is a preventable disease. [5] It can be managed with treatment and become a manageable chronic health condition. [5]

HIV-1 is the more commonly associated with AIDS in the US and worldwide, HIV-2 is more rare, and typically restricted to areas in western Africa and southern Asia. HIV-2 is so uncommon that “HIV” almost always refers to HIV-1. Alright HIV targets CD4+ cells, meaning cells that have this specific molecule called CD4 on their membrane.
According to the Centers for Disease Control, Ebola on dry surfaces, such as doorknobs and countertops, can survive for several hours; however, the virus in body fluids (such as blood) can survive ...
