The time interval during which the host is infectious, i.e. Both figures are used when calculating an R 0. eclipse period: the time between infection by (or induction of) a bacteriophage, or other virus, and the appearance of mature virus within the cell; an interval of time during which viral infectivity cannot be recovered. For example, the typical incubation period for hepatitis A is as long as 7 weeks. In some diseases, as depicted in this diagram, the latent period is shorter than the incubation period. The influence of the suspected induction/latent period on study design is considered. These estimates imply that, under conservative assumptions, 101 out of every 10 000 cases (99th percentile, 482) will develop symptoms after 14 days of active monitoring or quarantine. The disease then enters a dormant phase that can last weeks to years. The time required for development in the mosquito ranges from 10 to 28 days, depending on the parasite species and the temperature. The latent period is the period of time between when the host is 2. latency stage. The incubation period may be the same as the latent period (defined below) if the onset of symptoms is the same as the onset of infectiousness. The latent period is the period of time between when the host is infected to when he or she becomes infectious. latent period a seemingly inactive period, as that between exposure to an infection and the onset of illness (incubation period) or that between the instant of stimulation and the beginning of response (latency, def. Induction and latent periods are distinguishable concepts referring respectively to the period between causal action and disease initiation, and the period between disease initiation and detection. Many modeling studies assume that the EVD latent period is equal to its incubation period [1, 5, 6]. The latent period, rather than the incubation period, has more influence on the spreading dynamics of an infectious disease or epidemic. It refers to the time between acquiring the infection and the presentation of symptoms. When possible, it is best to express the mean and the 10th and 90th percentiles, though this information is not always available. During the incubation period, hosts can unwittingly spread an infection because they are not aware that they are carrying one. Latent period and eclipse period are two phases of bacteriophage growth. Other applications of a precisely described incubation period include predictive models that use the incubation period to accurately model the disease process, and the length of the incubation period in relation to the latent period (the time between infection and becoming infectious) determines the potential effectiveness of control measures that target symptomatic individuals .
