From the Highlights: " One new country/territory/area [...] has reported cases of COVID-19 [coronavirus disease 2019].  Data presented in the COVID-19 Situation Reports has changed to reflect data reported as of 00:00 CET [Central European Time]. As this is the first Situation Report with the new reporting period, there is overlap of data between Situation Report 57 and this report, thus the number of new cases may not equal the difference between total cases in the two reports.  WHO [World Health Organization] COVID-19 Situation Reports present official counts of confirmed COVID-19 cases, thus differences between WHO reports and other sources of COVID-19 data using different inclusion criteria and different data cutoff times are to be expected.  WHO, IFRC [International Federation of Red Cross], and UNICEF [United Nations International Children's Emergency Fund] jointly released the Risk Communication and Community Engagement (RCCE) Action Plan Guidance for COVID-19 on 16 March."
