Howard hughes medical institute, hhmi's biointeractive animations: „hiv life cycle -- how hiv infects a cell and replicates itself using reverse transcriptase and the host's cellular machinery. Hiv is a virus spread through certain body fluids that attacks the body's immune system, specifically the cd4 cells, often called t cells over time, hiv can destroy so many of these cells that the body can't fight off infections and disease.
Rates of sexually transmitted infections (stis) in canada are on the rise research suggests that stis can increase both a hiv-negative person's risk of becoming infected with hiv and an hiv-positive person's risk of transmitting hiv to someone else.

Hiv superinfection is when a person with hiv gets infected with another strain of the virus the new strain of hiv can replace the original strain or remain along with the original strain the effects of superinfection differ from person to person.
Biologically, four conditions need to be present for transmission to occur: virus must be present in an infectious body fluid from the hiv-positive person, it must be present at sufficient levels to cause infection, there must be an effective route of transmission, and it must reach susceptible cells in another person.

Hiv is a virus that lives in human blood, sexual fluids, and breast milk it weakens your immune system, so your body has a hard time fighting off common germs, viruses, fungi, and other invaders. Aids stands for acquired immune deficiency syndrome the diagnosis of aids is a way of describing a whole group of symptoms and diseases associated with the damage hiv does to the immune system if an untreated hiv infection progresses, there is ongoing damage to immune defense cells. Asymptomatic hiv infection is a phase of hiv/aids during which there are no symptoms of hiv infection during this phase, the immune system in someone with hiv slowly weakens, but the person has no symptoms.
Hiv is the virus that causes hiv infection aids is the most advanced stage of hiv infection hiv is spread through contact with the blood, semen, pre-seminal fluid, rectal fluids, vaginal fluids, or breast milk of a person with hiv. Hiv stands for human immunodeficiency virus it is the virus that can lead to acquired immunodeficiency syndrome or aids if not treated unlike some other viruses, the human body can't get rid of hiv completely, even with treatment. Human immunodeficiency virus (hiv) is the virus that causes acquired immune deficiency syndrome (aids) hiv destroys the body's immune system and eventually leads to aids people with aids develop many diseases and opportunistic infections (such as pneumonia, tuberculosis, cancer, and skin infections) that may ultimately lead to death.
