The latest Covid surge is stretching staffing to the limit at some Shasta County schools. Another 161 cases were reported from Monday alone. There are 90 Covid patients in the hospital, which is a new high, and 21 of them are in the ICU. The daily case rate has shot up to 54 per 100,000 residents. Pfizer’s COVID-19 vaccine has received full FDA approval, but no vaccine has been approved for children under 12. A number of Covid infections in Shasta County have occurred in vaccinated people, but they represent only a tiny fraction of the deaths and hospitalizations. Testing and vaccinations are free, with many options at shastaready.org.
