“Cloth face coverings – such as a bandana, scarf or homemade cloth cover – are now recommended when leaving the house for essential activities, announced Placer County Health Officer Dr. Aimee Sisson, to further slow the spread of COVID-19.
The new recommendation comes after increasing evidence that transmission of the virus can occur as early as three days before people develop symptoms. But health officials stress that face coverings should be used in tandem with, not in place of, other strategies.”
