About: Background: Epidemiological data provide important information for decision making. COVID-19 statistics from China fall outside of recognized and accepted medical norms. As the epicenter of the COVID-19 initial outbreak, the epidemiological information from Wuhan affects the response and preparation of other parts of China and rest of the world. Here we estimated the incidence, death and starting time of the COVID-19 outbreak in Wuhan and China based on medical literature from China, official and non-official Chinese data sources. Methods: Data sources included literature on COVID-19 in China, official Chinese government figures, state-run and non state-run media reports. Our estimates are based on investigative media reports of crematory operations in Wuhan, which is considered as a common data end point to life. A range of estimates is presented by an exponential growth rate model from lockdown (Jan 23,2020) until the intervention started to show effects, which was estimated 14.5 days after lockdown. Results: For the cumulative infections and total deaths, under different assumptions of death rates (from 2.5% to 10%) and doubling time 6.4 days, the estimates projected on February 7, 2020 in Wuhan range from 305,000 to 1,272,000 for infections and from 6,811 to 7,223 for deaths - on the order of at least 10 times the official figures (13,603 and 545). The implied starting time of the outbreak is October 2019. Under the assumption of the official 3.14% death rate and doubling time of 2.54 days (which was derived based on Chinese official data), the infection cases reached 2.2 million on February 7. The estimates of cumulative deaths, based on both funeral urns distribution and continuous full capacity operation of cremation services up to March 23, 2020, give results around 36,000, more than 10 times of the official death toll of 2,524. Conclusions: Our study indicates a significant under-reporting in Chinese official data on the COVID-19 epidemic in Wuhan. The magnitude of discrepancy between our estimates based on cremation related data and Chinese official figures in early February, the critical time for response to the COVID-19 pandemic, suggests the need to reevaluate official statistics from China and consider all available and reasonable data sources for a better understanding of the COVID-19 pandemic.   Goto Sponge  NotDistinct  Permalink
