The stages of HIV (Human Immunodeficiency Virus) can be categorized into three main stages:
1. Acute HIV infection: This is the initial stage that occurs within 2-4 weeks after contracting the virus. During this stage, individuals may experience flu-like symptoms such as fever, fatigue, sore throat, swollen lymph nodes, and rash. However, some people may not exhibit any symptoms at all. The virus rapidly replicates and spreads throughout the body, and the immune system starts producing antibodies to fight against it.
2. Clinical latency (Chronic HIV infection): Also known as the asymptomatic stage, this phase can last for several years. During this stage, the virus continues to replicate at a lower rate, but individuals may not experience any noticeable symptoms. However, HIV is still active and can be transmitted to others. Antiretroviral therapy (ART) is usually recommended during this stage to control the virus and prevent its progression.
3. AIDS (Acquired Immunodeficiency Syndrome): AIDS is the most advanced stage of HIV infection. It occurs when the immune system is severely damaged, and the CD4 T-cell count drops below 200 cells per cubic millimeter of blood (normal range is 500-1,600 cells/mm³). At this stage, individuals become highly susceptible to opportunistic infections and certain types of cancers. Symptoms may include rapid weight loss, chronic diarrhea, persistent fever, night sweats, extreme fatigue, and recurrent infections. Without treatment, AIDS can be life-threatening.
It is important to note that with early diagnosis and appropriate treatment, the progression of HIV can be significantly slowed down, and individuals can live long and healthy lives.
