Trump says 'toughest' weeks ahead as coronavirus spreads

The number of people infected in the U.S. has exceeded 300,000, with the death toll climbing past 8,400; more than 3,500 of those deaths are in the state of New York. For most people, the virus causes mild or moderate symptoms, such as fever and cough that clear up in two to three weeks. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia, and death.
