Mendocino County COVID-19 case rates are rising. After being assigned to the least restrictive yellow tier, Public Health Officer Dr. Andy Coren says a lot has changed in the last two weeks. New cases have nearly tripled, and more are in the hospital. He says they have seen this pattern in a surge. Coren’s advice is to get vaccinated and wear your masks in public, inside or outside, when you cannot keep 6 feet of distance from others who are not part of your household and may unwittingly carry this deadly virus. Coren also recommends getting tested monthly, whether or not you are vaccinated, especially before big events (graduation or other celebrations) or travel.
