Scientists are hard at work, trying to keep the coronavirus from spreading deeper across the country.
With the death toll at 120,000 and the threat of second wave of the virus in month, time is crucial.
Among the studies going on is a scientific review on masks by CDC researchers.
Scientists want to know if masks protect people from contracting COVID-19, not just prevent them from spreading it.
Studies have shown a significant number of people have coronavirus, but lack symptoms or are “asymptomatic.” They can still transmit the virus through talking, coughing and sneezing.

The new guidance is expected to soon.
