According to the CDC, 24% of spread is from asymptomatic people.About a third is from those who are pre-symptomatic, and 41% is from people experiencing COVID-19 symptoms, CNN reported.
The CDC says asymptomatic spread is why wearing masks is so important.
The CDC also adjusted its guidance Thursday to recommend that Americans do not travel for the Thanksgiving holiday next week, due to surging COVID-19 cases in many parts of the country.
The agency recommends that Americans celebrate the holiday at home with the people they live with, as gathering with family and friends from outside of the household can increase the chances of getting or spreading COVID-19 or the flu.
