Wearing a mask is important even if you aren’t exhibiting any symptoms of COVID-19, Dr. Epperson says, because an estimated 40 percent of transmissions occur before people are symptomatic.
In addition to wearing a face mask or covering, he says people should practice social distancing and good hand hygiene and follow established guidelines for quarantining or isolation if diagnosed with COVID-19, experiencing symptoms of the illness or exposed to someone with the disease.
It’s especially important for people at high risk from COVID-19 to limit their contact with others, he says, though it’s important for people of all age groups to continue receiving the medical care they need.
In case of emergency symptoms from COVID-19, immediately call 911.
“Everyone needs to do their part to stop the spread of COVID-19,” Dr. Epperson says. “Ultimately, by following these precautions, we can save lives.”
