Does the HIV virus live in your brain?
Recent research suggest that it might.
According to a study in the journal PLOS Pathogens, researchers found that HIV cells can hide in brain cells called astrocytes. Astrocytes make up about 60% of the total cells in our brain. If someone is infected with HIV, then 1% and 3% of those cells could have HIV hiding in them.
The issue with this is that it means HIV virus can be living and hiding within a patient, even after they are treated, and resurface later for re-infection.
