The director of the CDC says as many as 25 percent of people infected with coronavirus don’t show any symptoms. In an interview with NPR, Dr. Robert Redfield said those asymptomatic carriers are a big factor in the spread of the virus. Even for the remaining 75 percent, Redfield says those who are infected can be highly contagious for about 48 hours before symptoms first show up.
"Now is the time for us to over-invest [and] over-prepare in public health."
