» Several states are easing mask rules and other restrictions,

Texas on Tuesday became the biggest state to lift its mask rule, joining a rapidly growing movement by governors and other leaders across the U.S. to loosen COVID-19 restrictions despite pleas from health officials not to let their guard down yet.

The Lone Star State will also do away with limits on the number of diners who can be served indoors, said Republican Gov. Greg Abbott, who made the announcement at a restaurant in Lubbock.

The governors of Michigan, Mississippi and Louisiana likewise eased up on bars, restaurants and other businesses Tuesday, as did the mayor of San Francisco.

“Removing statewide mandates does not end personal responsibility,” said Abbott, speaking from a crowded dining room where many of those surrounding him were not wearing masks. “It’s just that now state mandates are no longer needed.”

A year into the crisis, politicians and ordinary Americans alike have grown tired of rules meant to stem the spread of the coronavirus, which has killed over a half-million people in the United States. Some places are lifting infection control measures; in other places, people are ignoring them.

Top health officials, including the head of the Centers for Disease Control and Prevention, have responded by begging people repeatedly not to risk another deadly wave of contagion just when the nation is making progress in vaccinating people and victory over the outbreak is in sight.

U.S. cases have plunged more than 70% over the past two months from an average of nearly 250,000 new infections a day, while average deaths per day have plummeted about 40% since mid-january.

But the two curves have leveled off abruptly in the past several days and have even risen slightly, and the numbers are still running at alarmingly high levels, with an average of about 2,000 deaths and 68,000 cases per day. Health officials are increasingly worried about virus mutations.

“We stand to completely lose the hard-earned ground we have gained,” CDC director Dr. Rochelle Walensky warned.
