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.
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 ...
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 ...
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 when symptoms and signs are first apparent. [ 1 ]
Symptomatic infections are apparent and clinical, whereas an infection that is active but does not produce noticeable symptoms may be called inapparent, silent, subclinical, or occult. An infection that is inactive or dormant is called a latent infection. [54] An example of a latent bacterial infection is latent tuberculosis.
A subclinical infection—sometimes called a preinfection or inapparent infection—is an ... the majority of those infected by Mtb bacteria have latent ...
Most infections show no symptoms, in which case it is known as latent tuberculosis. [1] Around 10% of latent infections progress to active disease that, if left untreated, kill about half of those affected. [1] Typical symptoms of active TB are chronic cough with blood-containing mucus, fever, night sweats, and weight loss. [1]
