Depends on the school district. However, much of the public-health work now deprioritizes HIV prevention (on the theory that with modern cocktail drugs, it's now "merely" a chronic disease easily managed, rather than a killer) in favor of a broader conversation about unprotected sex in general given other sexually transmitted illnesses.
It's a bit complicated in some places in the United States. In Michigan, for example, HIV status is legally "extra" protected under state law -- with drug use, behavior-health diagnoses and pregnancy -- from disclosure or targeting. So sometimes the people who'd benefit most from targeted education cannot be targeted because the relevant information cannot be used for that purpose.
