- 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.
