†As reported by China, which includes both laboratory confirmed and clinically diagnosed cases (currently only applicable to Hubei province, China)
• No new countries reported cases of COVID-19 in the past 24 hours.
• WHO is working with an international network of statisticians and
mathematical modelers to estimate key epidemiologic parameters of COVID19, such as the incubation period (the time between infection and symptom
onset), case fatality ratio (CFR, the proportion of cases that die), and the serial
interval (the time between symptom onset of a primary and secondary case).
Reports of current analyses that have estimated these parameters are
provided in this Situation Report as a summary of currently available
evidence. These values should be considered preliminary and parameters will
likely be updated as more information becomes available. Modelling can
support decision-making but needs to be combined with rigorous data
collection and a comprehensive analysis of the situation. Please see the
Subject in Focus section for more information.
• Several online courses related to COVID-19 have been added to the
o A general introduction to emerging respiratory viruses, including
novel coronaviruses (available in French, Simplified Chinese, and
Spanish as well).
o Critical Care of Severe Acute Respiratory Infections
