Final answer:
A disease that goes from symptomatic to asymptomatic then back again later is known as a latent disease. An example of a latent disease is herpes simplex virus.
Step-by-step explanation:
A disease that goes from symptomatic to asymptomatic and then back again later is known as a latent disease. This type of disease enters a dormant nonreplicative state after the acute disease and can persist in this state for years, with the risk of reactivation back into acute disease. An example of a latent disease is herpes simplex virus, which can remain asymptomatic for long periods of time before causing symptoms again.
