However, with HSV infections, better term is viral latency, which means that there are no infectious viral particles, but the viral genome still persists in the body, within the genome of the body's ...

virology

... In latent infections, overt dieases are not produced due to the fact that viruses are dormant but at the same time the dieases are not eradicated. Latency results in a virus being able to reactivate itself while also begin able to produce large amounts of viral progeny. Amounts of viral progency ...

No vaccine for HIV after 25 years ?

... there has also been troubles in choosing an effective antigen(s) for the vaccine. HIV also infects the immune system itself, and can have a long latency periods where the virus simply hides within certain leukocytes. Thus eradicating the virus from the body once the infection has begun is very ...
