The United States surpassed five 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.

Meanwhile, Brazil has become the second country in the world to pass 100,000 deaths from the coronavirus, second to the United States.
Brazil's President, Jair Bolsonaro, said last week he had "a clear conscience" despite the toll. Bolsonaro himself survived COVID-19 last month and said he had done "everything possible to save lives." Because of insufficient tests, experts say, the number of Brazilians with the virus could be six times higher.
