The county Department of Public Health reported 1,059 new cases Monday. On Friday, 1,044 coronavirus cases were reported countywide, followed by 1,069 more on Saturday and an additional 1,113 Sunday, according to data compiled by The Times. “Over 99% of the COVID-19 cases, hospitalizations and deaths we are seeing are among unvaccinated individuals,” county Public Health Director Barbara Ferrer said in a statement Monday. Sunday’s figure was particularly eye-popping because initial weekend case counts are typically artificially low because of reporting delays. The stream of new infections, though still small compared with the state’s fall-and-winter surge, has surrendered some of the county’s hard-won ground in the battle against COVID-19.
