Cases of COVID-19 are quickly rising in Kings County, and vaccination numbers are increasing slowly as the delta variant spreads, county supervisors were told during their weekly public health update Tuesday. Last week saw 354 new cases, and the number of confirmed delta variant cases jumped from eight to 20, though that number is probably low due to backups in the state testing lab, said Public Health Director Ed Hill. Of the 27 patients admitted at local hospitals for COVID-19, 88% were unvaccinated, though only 13% were Kings County residents â hospitals are regional and accept non-county residents. Among all vaccinated people in Kings, only .3% are experiencing breakthrough cases, Hill said.
