These lakes are the largest waterbodies, whether natural or constructed. These lakes, held back by dams, are the largest waterbodies serving water and power supply needs. Salt lakes are normally dry, appearing as glittering sheets of salt that stretch to the horizon.
The Incubation Period for Norovirus. The incubation period for an infection from norovirus typically take place throughout a time frame of 48 to 72 hours from the initial infection. This time usually defines the time between catching the infection and developing its associated symptoms.
We fit a log-normal distribution to pooled data and found the median incubation period to be 4.5 days (95% CI 3.9-5.2 days) for astrovirus, 1.2 days (95% CI 1.1-1.2 days) for norovirus genogroups I and II, 1.7 days (95% CI 1.5-1.8 days) for sapovirus, and 2.0 days (95% CI 1.4-2.4 days) for rotavirus.n PubMed we searched for the words âincubationâ, âperiodâ, and the virus name, on Google Scholar we searched for the phrases âincubation period of [virus name]â and âincubation period for [virus name]â, and on ISI Web of Knowledge we searched for âincubation periodâ and the virus name [ 20 ].
