The United States surpassed 5 million coronavirus cases on Sunday, the most in the world. 

The figures were released Sunday by Johns Hopkins University, which said the U.S. death toll is above 162,000. 

The Institute for Health Metrics and Evaluation has released a model predicting nearly 300,000 deaths by December 1 if Americans don’t start consistently wearing face masks.   

IHME Director Dr. Christopher Murray said in a statement that if 95% of Americans started wearing masks, more than 66,000 lives would be saved.
