Solution
The statement that is TRUE is: "The latent period is the time from exposure to onset of shedding of infectious agent."
Here's why:
-
The latent period is not always the same duration as the incubation period for a specific disease. These two periods can vary greatly depending on the disease in question.
-
The latent period is not the time from exposure to onset of clinical signs. This is actually the definition of the incubation period.
-
The latent period is indeed the time from exposure to onset of shedding of infectious agent. This is when the disease is able to spread, even if the host does not show any symptoms.
-
The incubation period is not the time from exposure to onset of shedding of infectious agent. As mentioned earlier, the incubation period is the time from exposure to the onset of clinical signs.
