The governor said that he was trying to get Texans to grasp the magnitude of the outbreak.
“There remain a lot of people in the state of Texas who think the spread of Covid-19 is really not a challenge,” he said.
In Maine, indoor bars won’t be reopening as planned. In Louisiana, occupancy limits will remain in place. And in Riley County, Kan., where case numbers grew more than 50 percent over the past week, officials said they would tighten restrictions on mass gatherings.
“I think we may have let our guard down a little bit,” said Julie Gibbs, the Riley County health officer. Several athletes at Kansas State University, which is in the county, have tested positive in recent days, and a majority of new cases have been in young adults.
Louisiana logged another 393 new cases on Monday, a trend seen after a period of sustained declines. Gov. John Bel Edwards, a Democrat, said it was not yet safe for businesses to reopen more fully. He noted that about 90 percent of new cases were coming from community spread, not nursing homes or other group living facilities.
“It is clear that Covid is alive and well in Louisiana, and as we see more people testing positive and admitted to hospitals, we simply are not ready to move to the next phase,” Mr. Edwards said.
In Maine, as in most of the Northeast, case numbers have continued to decline. But officials said clusters at restaurants and bars in other states caused them to retreat from plans to reopen bars for indoor service on July 1.
“As we learn more about how the virus spreads, duration and density — specifically, being in close quarters inside, as is the case with most bars — clearly elevate the risk of virus transmission,” said Dr. Nirav D. Shah, director of the Maine Centers for Disease Control and Prevention.
