The following were the leading counties in terms of deaths/population

Graphs of the ratios confirmed cases/population and deaths/population against the percent of Hispanic population in each California county are shown below, There are seen to be noticeable correlations (R2). The probability of a confirmed case is seen to be two to three times for counties with twice the percentage of Hispanic populations.
Give the "High Mortality from COVID-19 among Asian Americans in San Francisco and California" reported in https://asianarch.org/press_releases/Asian%20COVID-19%20Mortality%20Final.pdf, one would expect to find a strong correlation of deaths/population vs % Asian-American population for California counties. The labels on the charts below are the abbreviations for some of the counties (from https://sv08data.dot.ca.gov/contractcost/map.html).

The ratio of deaths/confirmed was about 2.5% mid April but had dropped to about 1.4% as of 7/26/2020. This may be related to the introduction of more effective treatments for the coronavirus over the past five months and the fact that hospitals are better prepared to handle patients (see https://www.sfchronicle.com/health/article/Why-coronavirus-cases-are-rising-but-deaths-are-15384724.php)..
