More coronavirus-related restrictions are likely coming to Solano County, officials there said Monday, as the county’s infection rate now exceeds the threshold for the purple reopening tier under the state’s guidelines.

According to an update on the county health department website, the county’s case rate for the week of Nov. 10 was 11.3 per 100,000 residents, well above the 7.0/100K maximum to avoid the most restrictive reopening tier. With one more week above the threshold, a swath of businesses will be forced to shut down or scale back indoor operations as soon as Nov. 24, the county says.
