Singapore MOH
DORSCON alert level WHO pandemic alert level Global/local situation Hospital measures Community measures
Green 0 1 No novel influenza virus circulating Triage and isolation of febrile patients, use of PPE as appropriate Surveillance, maintenance of antiviral drug stockpile
Green 1 2–3 Novel virus but predominantly animal disease with limited transmission to humans Full PPE for suspect cases, contact tracing for confirmed cases, antiviral treatment for all confirmed cases Enhanced surveillance, communication, readiness measures
Yellow 4 Inefficient human-to-human transmission of novel virus Full PPE for HCWs in high risk contact, visitor restriction, restrict movement of patients and HCWs Enhanced surveillance, public health education, border body temperature screening, surveillance of returned travelers from affected areas
Orange 5 Global or local clusters but transmission still localized PPE stepped up to cover “medium-risk” patients, no visitors, no interhospital movement of patients or HCWs, post-exposure prophylaxis for contacts Body temperature screening at community areas, consider school closure, body temperature screening at borders, enhanced public health education
Red 6 Pandemic under way, import into Singapore is inevitable As above with establishment of 18 influenza clinics As above with possible use of masks in the community
