Our model resembles theirs (Fig. 1 ), but we distinguish the prodrome and acute respiratory phase and allow infected people to become infectious before or after becoming ill, at rates-products of contact rates and probabilities of transmission on contact-that may differ among stages. A Mathematica TM notebook that evaluates these expressions for user-supplied parameter values, comparing the impact of non-pharmaceutical interventions on any disease transmitted by close contact, is available from the Table 1 Parameter estimates (b represents infection, r isolation efficiency, f hospitalization; subscripts E, P and R refer to pre-symptomatic, prodrome, and acute respiratory stage) from fitting predicted to observed cumulative admissions to TTSH during the first 30 days of the outbreak (cf.	./cache/cord-327681-c2kmog0g.txt	./txt/cord-327681-c2kmog0g.txt
