    en.wikipedia.org/wiki/Virus_latency

    A latent viral infection is a type of persistent viral infection which is distinguished from a chronic viral infection. Latency is the phase in certain viruses' life cycles in which, after initial infection, proliferation of virus particles ceases. However, the viral genome is not eradicated.

  3. Latent period (epidemiology) - Wikipedia

    en.wikipedia.org/wiki/Latent_period_(epidemiology)

    The period from the time of infection to the time of becoming infectious is called the pre-infectious period or the latent period. During the pre-infectious or latent period, a host may or may not show symptoms (i.e. the incubation period may or may not be over), but in both cases, the host is not capable of infecting other hosts i.e ...

    en.wikipedia.org/wiki/Incubation_period

    After the latency period (but before clinical infection) the infected person can transmit the disease without signs of any symptoms. Such infection is called subclinical infection. Incubation period (also known as the latent period or latency period ) is the time elapsed between exposure to a pathogenic organism, a chemical, or radiation , and ...

    An example of a latent bacterial infection is latent tuberculosis. Some viral infections can also be latent, examples of latent viral infections are any of those from the Herpesviridae family. [55] The word infection can denote any presence of a particular pathogen at all (no matter how little) but also is often used in a sense implying a ...

    Persons with HIV and latent tuberculosis have a 10% chance of developing active tuberculosis every year. "HIV infection is the greatest known risk factor for the progression of latent M. tuberculosis infection to active TB. In many African countries, 30–60% of all new TB cases occur in people with HIV, and TB is the leading cause of death ...

    The lytic phase of infection occurs within mucoepithelial cells while the latent infection of these cells occurs in neurons. These two viruses are the cause of oral and genital herpes. [4] Latency is maintained in a variety of ways, one of which is the latency-associated transcript, or LAT. This long non-coding RNA accumulates in the latent ...
