Ramaswami: Mike Ryan, executive director of WHO Health Emergencies Programme, stated in press conference on February 24, “It is time to do everything you would do in preparing for a pandemic. But in declaring something a pandemic its too early...When we mean prepare we mean to detect cases, prepare to treat cases, prepare to follow contacts, prepare to put in place adequate containment measures. It’s not a hundred different measures there are probably 5 or 6 key interventions.”
