  1. *Literature estimates show the range of incubation periods consistent with most published estimates and the most frequently stated central tendency (eg. median, mean) for the incubation period; estimates that did not specify a type (eg. “the incubation period is 5 days”) were assumed to be statements of central tendency. ψObservational studies did not always report a defined number of participants, so a subject count is only reported for experimental studies.
