Alright students, today we are going to learn about HIV.

Right now, about 39 million people in the world are confirmed to have HIV. But if we include those who have not been diagnosed yet, the number may go beyond 50 million.

HIV mainly spreads through sexual contact. At first, most people do not even know they are infected.

In the first stage, called the acute infection stage, some people may feel muscle pain and fever like the flu. These symptoms usually go away in a few days.

Next is the latent stage. Even though people feel fine, the virus slowly destroys the immune system, especially
CD4 T cells. This stage can last for several years, even more t han ten years.

Then comes the symptomatic stage. The body becomes weaker, and even small infections last longer. Some people lose weight or get fungal infections.

The final stage is AIDS. The immune system is very damaged. Serious infections and certain cancers can happen. Without treatment, a person can die within months.

But with regular antiretroviral therapy, people can live much longer and healthier lives. So always take care of your health.
