COVID‐19 = coronavirus disease 2019.

^* Ill person refers to someone with symptoms of respiratory illness or fever, who is not yet under investigation for COVID‐19 but could be an unrecognised case.

^†This could be costly unless used judiciously while awaiting exclusion of COVID‐19 in the suspected case and should be introduced based on likelihood of local transmission.

^‡Evidence that low temperature and low humidity in air‐conditioned environments may enhance the survival of coronaviruses such as severe acute respiratory syndrome (SARS).11
