The Bay Area had its deadliest day in the pandemic on Friday, reporting 34 new COVID-19 fatalities, a number lead by double-digit death counts in Alameda and Santa Clara counties.

The new deaths bring the total of fatalities in the nine-county Bay Area, plus Santa Cruz County, to 1,278, and break a record for most deaths reported in one day set a little more than a week ago, when the counties reported 30 deaths on Sept. 3, according to data compiled by this news organization. The 34 deaths include 16 fatalities reported in Alameda County, the third-most ever in that county, and 13 in Santa Clara County, the most ever there.
