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 ...
In a typical infectious disease, the incubation period signifies the period taken by the multiplying organism to reach a threshold necessary to produce symptoms in the host. While latent or latency period may be synonymous, a distinction is sometimes made whereby the latent period is defined as the time from infection to infectiousness. Which ...
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 time of Marburg virus disease could only be estimated retrospectively, after the source of infection and the date of exposure were known. Incubation ranged from 5 to 9 days, with an average of 8 days. The ratio of primary to secondary infections was 21:3 in Marburg, 4:2 in Frankfurt, and 1:1 in Belgrade.
Incidence – rate of new cases of a disease occurring in a specific population within a defined time period, typically expressed per 1,000 or 100,000 individuals. Inequality in disease – disparities in the burden (distribution and impact) of infectious diseases among different population groups, often due to social determinants of health.
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 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]
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]
