HIV: Third case in the world of probable cure after a bone marrow transplant

After a stem cell transplant from a donor with the CCR5-delta 32 mutation, a man was able to stop his antiretroviral treatment without viral resurgence. Four years later, no HIV virus could be detected in his body, indicating probable cure. This case joins two previous reported cases and offers further proof that HIV can be cured.

Black people less likely to receive dementia-related medications
