You are told in report that your patient has a history of HIV, the chart 
states HIV negative. Can both be correct? Actually, yes.

People who take antiretroviral therapy (ART) daily as prescribed can 
achieve and maintain an undetectable viral load (the amount of HIV in 
the blood). Also, those who maintain an undetectable viral load cannot 
sexually transmit the virus to others.

To put it simply: Undetectable = Untransmittable (U=U). You will probably start noticing more U=U 
informational campaigns going on.
