diseases and their transmission, however statements of incubation period in the literature are often uncited,\r\ninconsistent, and/or not evidence based.\r\nMethods: In a systematic review of the literature on five enteric viruses of public health importance, we found 256\r\narticles with incubation period estimates, including 33 with data for pooled analysis.\r\nResults: We fit a log-normal distribution to pooled data and found the median incubation period to be\r\n4.5 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\r\n(95% CI 1.5-1.8 days) for sapovirus, and 2.0 days (95% CI 1.4-2.4 days) for rotavirus.\r\nConclusions: Our estimates combine published data and provide sufficient quantitative detail to allow for these\r\nestimates to be used in a wide range of clinical and modeling applications. This can translate into improved prevention\r\nand control efforts in settings with transmission or the risk of transmission.
