CDC Reiterates Mask Recommendations as Virus Continues to Spread

States and cities might have to resume lockdowns if Covid-19 cases surge dramatically, top officials at the U.S. Centers for Disease Control and Prevention said at their first press briefing in months.

The officials offered little in the way of explanation for why cases are increasing in some parts of the country, releasing little new data on what’s driving up cases in states such as Arizona, Texas and Oregon. They focused on reminding people to continue taking the same precautions the CDC has been recommending: Wear masks, keep six feet apart, wash your hands.
