SARS incubation and quarantine times: when is an exposed individual known to be disease free?	2005-10-19		.txt	text/plain	4727	232	55	For the data set of averaged times, Figure 1 presents the proÿle likelihoods, L * P (M ), based on the gamma, log-normal and log-gamma models discussed in Section 2. For the truncated gamma model, the proÿle likelihood never drops below 60 per cent suggesting that any value of M greater than the maximum time observed, 14, is plausible. For public health purposes, it could therefore be argued that, based only on such data and an assumed log-normal model, that a quarantine time of 20 days might be necessary to ensure that SARS cases were not released 'too early'. Finally, to show the e ect of more extreme interval-censoring, we consider extending the set of data in Table II by including additional SARS cases from Hong Kong whose period of possible exposure, which deÿnes the width of the interval within which their incubation time lies, is thought to be less than 10 days rather than 5 days.	./cache/cord-340260-z13aa1wk.txt	./txt/cord-340260-z13aa1wk.txt
