7Healthcast: Early detection of HIV

New research suggests the AIDS virus can spread and replicate in patients’ brains shortly after they are infected.

In 10-30 percent of patients, the virus separately evolved in the brain within the first months of infection.

That means AIDS can later re-infect the body even if it is eliminated from the blood and lymph node tissue.

Experts say these findings confirm the importance of early diagnosis and treatment of HIV.
