How is The status of the immune system in someone with HIV infection can be monitored by checking?

The level of CD4+ T cells

Explanation:

CD4+ T cells are a type of white blood cell that plays a crucial role in the immune system's ability to fight off infections. In HIV infection, the virus specifically targets and destroys CD4+ T cells, progressively weakening the immune system. As the number of CD4+ T cells declines, the person becomes more susceptible to various opportunistic infections and other complications associated with HIV. Monitoring the level of CD4+ T cells is considered a key indicator of the status of the immune system in individuals with HIV infection. It helps to assess the stage of the disease, guide treatment decisions, and track the effectiveness of antiretroviral therapy. Regular monitoring of CD4+ T cell counts allows healthcare providers to closely monitor the immune system's health and make necessary adjustments to the treatment plan.
