Human Immunodeficiency Virus (HIV)
HIV disease continues to be a serious health issue for parts of the world.
HIV attacking a cell.
In 2021, it was estimated that there were approximately 38 million people living with HIV worldwide. Of these, about 27.5 million people were receiving antiretroviral therapy (ART) to treat HIV.
The Human immunodeficiency virus attacks and suppresses the immune system, reducing a person's ability to fight infection. The virus specifically targets the cells crucial for fighting infection from pathogens. This allows diseases and infections to progress without resistance.
Within a few weeks of being infected with HIV, some people develop flu-like symptoms that last for a week or two, but others have no symptoms at all. People living with HIV may appear and feel healthy for several years. However, even if they feel healthy, HIV is still affecting their bodies. Untreated early HIV infection is also associated with many diseases including cardiovascular disease, kidney disease, liver disease, and cancer.
