10 January 2020

WHO issued a comprehensive package of technical guidance online with advice to all countries on how to detect, test and manage potential cases, based on what was known about the virus at the time. This guidance was shared with WHO's regional emergency directors to share with WHO representatives in countries.

The lead also said that human-to-human transmission would not be surprising given our experience with SARS, MERS and other respiratory pathogens.
