Redding Health Officer Doug Hartline is back to providing daily updates to town residents about COVID-19. He says with what looks to be the start of the 4th wave of increased cases, Redding is requiring mask wearing in all municipal buildings. Hartline notes that vaccines continue to be proven safe and highly effective. Most new COVID cases that result in severe symptoms are occurring among the unvaccinated. He added that the risk of contracting and transmitting COVID infection is far greater for the unvaccinated. Infections in fully vaccinated tend to be mild, however in some cases fully vaccinated people who do become infected with the Delta variant can be infectious and can spread the infection to others.
