What can be a consequence of a CD4 count falling below 200 cells/mm3?

A CD4 count falling below 200 cells/mm3 is significant as it indicates severe immunosuppression in individuals living with HIV. This level of CD4 count is a critical threshold for the diagnosis of Acquired Immunodeficiency Syndrome (AIDS). When the CD4 count drops to this level, the individual becomes much more vulnerable to opportunistic infections and certain cancers that a healthy immune system would typically be able to fight off.

A person with a CD4 count below 200 is classified as having AIDS, which reflects a progression of HIV infection and signifies the need for more intensive medical management. This condition highlights the importance of regular monitoring of CD4 counts in people living with HIV to assess the effectiveness of antiretroviral therapy and the overall health of the individual.

Other potential options in the context of this question do not accurately reflect the outcomes associated with a low CD4 count, as they suggest either an improvement in symptoms or a stable condition without addressing the increased risk for serious health complications.
