Data through 11 February 2020.[105] Case fatality rate depending on other health problems Epidemiology Total confirmed cases of COVID-19 as of March 12, 2020 Overall mortality and morbidity rates due to infection are not well established; while the case fatality rate (CFR) changes over time in the current outbreak, the proportion of infections that progress to diagnosable disease remains unclear.[106][107] However, preliminary research has yielded case fatality rate numbers between 2% and 3%;[14] in January 2020 the WHO suggested that the case fatality rate was approximately 3%,[108] and 2% in February 2020 in Hubei.[109] Other CFR numbers, which adjust for differences in time of confirmation, death or cured, are respectively 7%[110] and 33% for people in Wuhan 31 January.[111] An unreviewed preprint study by Imperial College London among 55 fatal cases noted that early estimates of mortality may be too high as asymptomatic infections are missed. This brought the total confirmed US deaths due to coronavirus to 22: 19 in Washington, 1 in California, and 2 in Florida. You can share your experience by emailing haveyoursay@bbc.co.uk. Evolution The most recent common ancestor (MRCA) of all coronaviruses has been placed at around 8000 BCE.[26] The MRCAs of the Alphacoronavirus line has been placed at about 2400 BCE, the Betacoronavirus line at 3300 BCE, the Gammacoronavirus line at 2800 BCE, and the Deltacoronavirus line at about 3000 BCE. 29, as reported by the National Health Commission (NHC) of China.
