The lightning-fast global surge in Covid cases brought on by the Omicron variant has not spared Marin. Last week, the county’s daily caseloads blew past their previous record, despite high vaccination rates. “Most of us will experience infection personally or in our immediate family or social circles,” said Matt Willis, the county’s public health officer, on Tuesday. “That’s the reality of Omicron.” But as more evidence confirms that the variant produces milder symptoms, the county will continue to focus on hospitalizations rather than caseloads. Covid hospitalizations have climbed slightly since November, but Dr. Willis said hospitals count anyone who tests positive as a Covid patient, even if they were hospitalized for an unrelated condition. He said he is working with Marin’s hospitals to begin distinguishing between patients hospitalized “with Covid” and “for Covid.” Keeping schools open remains a priority in Marin, and the new shortened quarantine guidance from the Centers for Disease Control will help minimize disruptions to schools and health care facilities, he said. In West Marin, community organizations are planning to provide rapid at-home tests, which have become nearly impossible to find at pharmacies. West Marin Community Services, the San Geronimo Valley Community Center and the Tomales Town Hall are among the groups collaborating on a plan to distribute iHealth antigen tests provided by the California Department of Public Health. The availability of at-home tests will help ease the burden on local testing sites, said Seamus Tomkins, a project coordinator at W.M.C.S. “It’s been really hard for us to keep up, so I’m thankful that we now have this other method of distribution through the take-home tests,” he said.
