Coronavirus disease 2019 (COVID-19) - Worldintr
Following the notification of the occurrence of cases of COVID-19 among travelers from Wuhan, China in early January, WHO set up a Global Surveillance System to collect and organize essential information to describe and monitor the extent of the global outbreak. The goals of global surveillance are to: 1) Monitor the global extent of the epidemic; 2) Provide early epidemiological information to support risk assessment at the national, regional and global levels; 3) Rapidly detect new cases in countries where the virus was not previously circulating; 4) Monitor trends of the disease after a first case is imported and; 5) Provide epidemiological information to guide response measures. In line with the International Health Regulations (2005), all Member States’ IHR National Focal Points were requested to immediately report any new confirmed case of COVID-19 and, within 48 hours, provide information related to clinical, epidemiological, and travel history using the WHO standardized case reporting form. The current version of the case reporting form can be found here in Arabic, Chinese, English, French, Russian, Spanish and Portuguese
WHO regions implemented immediate reporting of COVID-19 cases through systems already in place – such as The European Surveillance Systemin the European Region, EMFLU in the Eastern Mediterranean Region, and FluNet in the Americas Region; or by setting up a new electronic data collection system (South-East Asia region).The flow of data from WHO Regional Offices to WHO HQ was organized using the existing Global Influenza Surveillance system, allowing regions to rapidly transfer information. A Global Surveillance COVID-19 database centralizing all COVID-19 cases reported from outside China is maintained at WHO HQ, and data analysis is conducted daily to: follow the transmission of the disease between countries; describe the characteristics of human- to- human transmission within clusters of cases; describe the characteristics of affected persons and their exposure measures implemented in response to the history; and
