HIV is a virus that attacks the immune system, specifically the CD4+ T cells. These are white blood cells that help the body fight infections. When HIV enters a CD4+ T cell, it destroys the cell's ability to function properly. This leads to a weakened immune system, increasing the risk of getting sick and developing certain diseases.
Transmission:
HIV is spread through contact with infected blood, semen, vaginal fluids, and breast milk. Unprotected sexual activity, including anal and oral sex, can transmit HIV. Sharing needles or other drug paraphernalia can also spread the virus.
Symptoms:
The early stage of HIV infection often shows no symptoms. However, as the disease progresses, symptoms may appear, including:
Fever
Fatigue
Swollen lymph nodes
Sore throat
Night sweats
Skin rash
Diarrhea
Pneumonia
Opportunistic encephalitis (a rare but severe form of brain infection)
Diagnosis:
HIV is diagnosed through blood tests that detect the presence of antibodies against HIV in the body.
Treatment:
There is no cure for HIV, but it can be managed with medication. Antiretroviral therapy (ART) is a combination of medications that help suppress the virus and prevent its replication. With early diagnosis and treatment, people with HIV can live long and healthy lives.
Prevention:
The best way to prevent HIV transmission is to abstain from sexual activity, avoid sharing needles or other drug paraphernalia, and practice safe sex by using condoms during each sexual encounter. Regular medical check-ups are also essential for early detection and management of the disease
