At this stage we may speak of 'an infection' (which may be symptomatic or asymptomatic). Latent viruses and diseases Latent viruses are those viruses that can incorporate their genetic material into the genetic material of the infected host cell. The time interval between inoculation and the appearance of disease symptoms is called the incubation period. The period between exposure and infection is called 'latent period', since the pathogen is present in a 'latent' stage, without clinical symptoms or signes of infection in the host.
