In Scenario 1: Short, sporadic chains of transmission, learning about the epidemiology of the virus is paramount. While the number of cases remains small, active case finding, including contact tracing, should be conducted. Swabbing of asymptomatic individuals may be considered. It is of paramount importance that contacts of cases are properly managed [3]. Cases should be isolated to avoid further transmission. The potential adaptation of influenza surveillance systems should be evaluated. It is now also advisable for countries to review their pandemic preparedness plan, including healthcare system surge capacity and plans for business and essential service continuity. Alternative supply chains should be identified for personal protective equipment and other healthcare consumables; stockpiling should be considered as supply chains may later be disrupted. Risks should be communicated in a transparent and consistent way to stakeholders and to the general public, according to the unfolding epidemiological situation. Messages should include the actions being taken with acknowledgement of uncertainty.
