Oakland and Hayward topped the list of Alameda County cities with the most confirmed cases of covid-19, according to a dashboard released to the public on Wednesday.

The dashboard provided by the Alameda County Health Care Services Agency includes only general statistics, such as the age range of those confirmed to have been infected and the city where they reside.

Below is the number of covid-19 cases sorted by city, through April 7.

As the largest city in Alameda County, it’s no surprise Oakland has the most confirmed cases with 137, through Tuesday, when a grand total of 631 cases were reported.

Hayward, which is nearly three times the size of Oakland, however, registered the second highest number of cases to date. The large number of cases may be attributed to an outbreak of cases at a nursing home in Hayward.

Hayward is also the site of the first free testing site offered to the general public almost three weeks ago.

Unincorporated Alameda County, whose total size rivals that of Hayward, has 70 confirmed cases of covid-19. Both areas have vulnerable older and low-income residents. Similarly, roughly cases were confirmed at a nursing home in Castro Valley.

Alameda County residents between the ages of 45-54 years old make up, by far, the largest age demographic of confirmed cases with 232. The second-most being 121 county residents between 65 and 74 years old.

Alameda County health officials said on Tuesday afternoon that a dashboard of covid-19 statistics would be available sometime this week. Colleen Chawla, the Alameda County Health Care Services Agency director, said the ethnicity of covid-19 cases in the county would not be released to the public due to the potential for the low sample size of current cases skewing the results.
