Masking is associated with a reduction in the daily number of COVID-19 cases and a growth rate of death within 20 days of application, according to a new study by the US Centers for Disease Control and Prevention (CDC).
To examine the link between state-issued mask mandates and the provision of lunch at local restaurants with COVID-19 cases and deaths from March 1 to December 31 last year, the CDC compared data on mask mandates and reopening of restaurants at the county level. changes in the level in the case of COVID-19 and the growth rate of death in relation to the implementation of the mandate and the reopening dates.
The study shows that the issuance of mandatory masks is associated with a decrease in the daily number of cases of COVID-19 and an increase in deaths within 20 days of application.
Meanwhile, enabling dining at local restaurants has been linked to an increase in daily growth rates of the COVID-19 case 41 to 100 days after application and an increase in daily growth rates of death 61 to 100 days after application, according to a study released Friday.
Mask orders and restrictions on any local dining in restaurants could help limit COVID-19 transmission in the community and reduce the growth rate of cases and deaths, the CDC said.
