After the virus enters the body there is a period of rapid viral replication, leading to an abundance of virus in the peripheral blood. During primary infection, the level of HIV may reach several million virus particles per milliliter of blood. [2] This response is accompanied by a marked drop in the numbers of circulating CD4 + T cells.
The human immunodeficiency viruses (HIV) are two species of Lentivirus (a subgroup of retrovirus) that infect humans.Over time, they cause acquired immunodeficiency syndrome (AIDS), [1] [2] a condition in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive.

Criminal transmission of HIV is the intentional or reckless infection of a person with the human immunodeficiency virus (HIV). Some countries or jurisdictions, including some areas of the United States, have laws that criminalize HIV transmission or exposure. [298] Others may charge the accused under laws enacted before the HIV pandemic.
Body substance isolation is a practice of isolating all body substances (blood, urine, feces, tears, etc.) of individuals undergoing medical treatment, particularly emergency medical treatment of those who might be infected with illnesses such as HIV, or hepatitis so as to reduce as much as possible the chances of transmitting these illnesses.

HIV (human immunodeficiency virus) damages the body's immune system, which interferes with its ability to fight off disease-causing agents. The virus kills CD4 cells, which are white blood cells that help fight off various infections. HIV is carried in body fluids and is spread by sexual activity.
Male-to-male transmission is the most common mode of transmission in the US, and male-to-female is the most common mode in resource-limited settings. Although less common, female-to-male transmissions occur as well since HIV is present in the vaginal and cervical fluids of infected women.
A microbicide for sexually transmitted diseases is a gel which would be applied to the skin – perhaps a rectal microbicide for persons who engage in anal sex or a vaginal microbicide for persons who engage in vaginal sex – and if infected body fluid such as blood or semen were to touch the gel, then HIV in that fluid would be destroyed and ...
HIV prevention refers to practices that aim to prevent the spread of the human immunodeficiency virus (HIV). HIV prevention practices may be undertaken by individuals to protect their own health and the health of those in their community, or may be instituted by governments and community-based organizations as public health policies.
