HIV (Human Immunodeficiency Virus) is the virus that causes HIV infection, while AIDS (Acquired Immunodeficiency Syndrome) is the most severe phase of the infection. HIV attacks the body's immune system, specifically the CD4 cells (T cells), which are crucial for fighting infections. If left untreated, HIV reduces the number of CD4 cells, making the body more susceptible to other infections and certain cancers
The primary modes of HIV transmission include unprotected sexual contact, sharing needles, and from mother to child during childbirth or breastfeeding. HIV is not spread through casual contact such as hugging, shaking hands, or sharing utensils.
Treatment for HIV involves antiretroviral therapy (ART), which helps manage the virus and maintain a low viral load, thus preventing the progression to AIDS. ART has been proven to extend the lifespan of those living with HIV, allowing them to lead healthy lives. Consistent use of ART can also reduce the risk of transmitting the virus to other.
