What is latent period?
Latent period (epidemiology), the time interval between when an individual is infected by a pathogen and when he or she becomes capable of infecting other susceptible individuals..
What virus has the shortest incubation period?
Missing from the table (which will be corrected in the next edition) is the incubation period of Ebola virus, which is 2 to 21 days. I would also argue that the incubation period of HIV is not 1-10 years, but 2-4 weeks, the time until the prodromal symptoms occur.
Does the duration of the latent period change?
Predict Question 1: No, changes to the stimulus intensity will not change the duration of the latent period. The latent period is a chemical event initiated by the stimulus regardless of its intensity.
Which disease has longest incubation period?
Even for a single disease, the characteristic incubation period has a range. For example, the typical incubation period for hepatitis A is as long as 7 weeks. The latency period for leukemia to become evident among survivors of the atomic bomb blast in Hiroshima ranged from 2 to 12 years, peaking at 6–7 years.
How long does it take a virus to pass?
The virus usually enters your body 1 to 4 days before you have any symptoms, and you can give it to someone a day before you feel anything up to 5 to 7 days after. And kids are contagious even longer. They can spread the virus for another week.
Which stage of infectious illness is characterized by a latent 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. The period between exposure and onset of clinical symptoms is called ‘incubation period’.
Which period is called the latency period?
In epidemiology, particularly in the discussion of infectious disease dynamics (modeling), the latent period (also known as the latency period or the pre-infectious period) is the time interval between when an individual or host is infected by a pathogen and when he or she becomes infectious, i.e. capable of …
What is an incubation period of a disease?
The incubation period is the time from exposure to the causative agent until the first symptoms develop and is characteristic for each disease agent.
Why do viruses have incubation periods?
The infection of multiple cells in the body and subsequent replication of the virus takes time. While the virus remains at low levels, it can neither be detected nor transmitted. This is why this time is known as the virus’ incubation period.
What is latency disease?
Latency, in the sense of the term as used in the discussion, implies the possibility of a disease germ lying quiescent for a longer or shorter period after its introduction instead of at once showing its virulency in the usual way, and the microbes of hydrophobia, syphilis, tuberculosis and leprosy were referred to as …
What happens if the latent period for an infection is longer than the incubation period?
If the latent period is shorter than the incubation period, then individuals are infectious before they have symptoms. This can help the infection to spread more easily. If the latent period is longer than the incubation period, then people are infectious only after symptoms start.
