The present mainly focus on 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 history; and support the evaluation of public health measures implemented in response to the epidemic. a combination of public health measures, such as rapid identification, diagnosis and management of the cases, identification and follow up of the contacts, infection prevention and control in health care settings, implementation of health measures for travelers, awareness-raising in the population and risk communication. China has revised their guidance on case classification for COVID-19, removing the classification of “clinically diagnosed” previously used for Hubei province, and retaining only “suspected” and “confirmed” for all areas, the latter requiring laboratory confirmation. Some previously reported “clinically diagnosed” cases are thus expected to be discarded over the coming days as laboratory testing is conducted and some are found to be COVID-19-negative. In early January, following the notification of the occurrence of cases of COVID-19 among travelers from Wuhan, China, WHO established a Global Surveillance System to collect and organize essential information to describe and monitor COVID-19. All WHO regions have implemented the reporting of COVID-19 cases either through existing or newly-established data collection systems
