HIV Infection – Causes, Symptoms, Diagnosis, Treatment, and Prevention

HIV (Human Immunodeficiency Virus) infection is a chronic disease that affects the immune system. It is caused by the transmission of the virus through certain body fluids, such as blood, semen, vaginal fluid, or breast milk. HIV can be transmitted through unprotected sexual intercourse, sharing needles and syringes, and from an infected mother to her child during pregnancy, childbirth, or breastfeeding.

Once the virus enters the body, it starts to attack and destroy the CD4 cells, which are a type of white blood cells that play a crucial role in maintaining a healthy immune system. As a result, the immune system weakens, and the infected individual becomes more susceptible to various infections and diseases.

The symptoms of HIV infection can vary from person to person and can resemble flu-like symptoms, such as fever, fatigue, sore throat, and swollen lymph nodes. However, some individuals may not experience any symptoms at all, especially during the early stages of the infection. Therefore, getting a proper diagnosis is essential.

There is currently no cure for HIV, but with early detection and appropriate treatment, the progression of the disease can be slowed down. Antiretroviral therapy (ART) is the most common treatment for HIV infection. It involves taking a combination of medications that help control the virus and improve the immune system’s function. Additionally, various supportive measures, such as regular medical check-ups, healthy lifestyle choices, and mental health support, are crucial for managing this chronic condition.
