HIVvirusta

HIVvirusta, also known as Human Immunodeficiency Virus, is a lentivirus that attacks the body's immune system. It is primarily transmitted through unprotected sexual contact, sharing needles, and from mother to child during pregnancy, childbirth, or breastfeeding. The virus targets and infects CD4 cells, a type of white blood cell crucial for the immune system's function.

HIVvirusta has a complex life cycle involving reverse transcription, where the viral RNA is converted into DNA, which is then integrated into the host cell's genome. This integration allows the virus to replicate and produce new viral particles. The virus can remain dormant for years, but it eventually leads to a decline in CD4 cell counts, a condition known as AIDS (Acquired Immunodeficiency Syndrome).

There is no cure for HIVvirusta, but antiretroviral therapy (ART) can manage the virus, allowing infected individuals to live long, healthy lives. ART involves a combination of drugs that inhibit the virus's replication. Regular testing and adherence to treatment are essential for managing the virus effectively.

Prevention strategies include safe sex practices, using clean needles, and prenatal care to prevent mother-to-child transmission. Vaccines are in development but are not yet widely available. HIVvirusta is a significant global health issue, with millions of people living with the virus and millions more at risk.
