During daily media briefing on the novel coronavirus outbreak on Wednesday, Dr. Tedros Adhanom Ghebreyesus, the Director General of the WHO, said that more than 90% of the global total of novel coronavirus cases are coming from four countries, and two of them - China and South Korea - are reporting declining numbers of new cases. Dr. Ghebreyesus added that all countries can still change the course of this pandemic if they “detect, test, treat, isolate, trace and mobilize their people in the response.”
