Here is a new study. If this study is accurate, this study would once again demonstrate that the fatality rate is a fraction of the estimate by WHO.

USC and the Los Angeles County Department of Public Health on Monday released preliminary results from a collaborative scientific study that suggests infections from the new coronavirus are far more widespread — and the fatality rate much lower — in L.A. County than previously thought.
The results are from the first round of an ongoing study by USC researchers and county health officials. They will be conducting antibody testing over time on a series of representative samples of adults to determine the scope and spread of the pandemic across the county.
Based on the results of the first round of testing, the research team estimates that
approximately 4.1% of the county’s adult population has an antibody to the virus. Adjusting this estimate for the statistical margin of
error implies about 2.8% to 5.6% of the county’s adult population has an antibody to the virus — which translates to approximately 221,000 to 442,000 adults in the county who have been infected. That
estimate is 28 to 55 times higher than the 7,994 confirmed cases of COVID-19 reported to the county at the time of the study in early April. The number of COVID-related deaths in the county has now surpassed 600.
