The terms "intrinsic incubation period" and "extrinsic incubation period" are used in vector-borne diseases. The intrinsic incubation period is the time taken by an organism to complete its development in the definitive host. The extrinsic incubation period is the time taken by an organism to develop in the intermediate host. [citation needed]
The relationship between the latent period, the infectious period (the period of communicability) and the incubation period. In some diseases, as depicted in this diagram, the latent period is shorter than the incubation period. A person can transmit an infection without showing any signs of the disease.
The serial interval in the epidemiology of communicable (infectious) diseases is the time between successive cases in a chain of transmission. [1]The serial interval is generally estimated from the interval between clinical onsets (if observable), in which case it is the 'clinical onset serial interval'.
The incubation period is important in the dynamics of disease transmission because it determines the time of case detection relative to the time of infection. [1] This helps in the evaluation of the outcomes of control measures based on symptomatic surveillance. The incubation period is also useful to count the number of infected people. [1]
An epidemic curve, also known as an epi curve or epidemiological curve, is a statistical chart used in epidemiology to visualise the onset of a disease outbreak. It can help with the identification of the mode of transmission of the disease. It can also show the disease's magnitude, whether cases are clustered or if there are individual case ...
Fifth Disease, or parvovirus B19, also known as erythema infectiosum. Roseola, a viral infection occasionally still called Sixth disease, which can cause high fever and rash.
The incubation period (the time between exposure to an infection and the onset of symptoms) is usually between 4 and 21 days. Viremia (a condition which occurs when viruses enter the bloodstream and eventually spread to the rest of the body) occurs within 5 to 10 days from exposure to Parvovirus B19, and the person remains contagious 5 days ...
Human parvovirus B19, generally referred to as B19 virus (B19V), parvovirus B19 [1] or sometimes erythrovirus B19, [2] is a known human virus in the family Parvoviridae, genus Erythroparvovirus; it measures only 23–26 nm in diameter. [3]
