Khan said there are multiple measures that can help “get this outbreak under control, starting with test and trace,” which he noted has been successful in Europe, Canada, and many other countries that have eliminated the virus. “If you can’t get those right, your only option is to shut down,” Khan said.ae0fcc31ae342fd3a1346ebb1f342fcb He added that these are the things that “we know work” when it comes to containing COVID-19: “leadership; test and trace, get cases down in our community; wear masks, wash your hands, the community engagement part.” Some states, Khan noted, are already rolling back on their reopening plans. “They’re shutting down bars. They’re shutting down restaurants, because if people don’t come in contact with each other … they can’t cause disease,” he said.

In early July, Texas governor Greg Abbott, for example, ordered bars to stop serving alcohol on site and also for dine-in restaurants to decrease capacity. Most other businesses, meanwhile, remain open. Abbott also issued a mask mandate earlier this month. In Arizona, Gov. Doug Ducey also shut down bars and ordered gyms, theaters, and water parks to close as well. Arizona, however, does not have a statewide mask requirement. In both Arizona and Texas, churches, retail stores, salons, and other businesses remain opened. Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases (NIAID), sent a similar message to Khan’s on July 8 regarding future lockdowns. “I think any state that is having a serious problem, that state should seriously look at shutting down,” he said on The Wall Street Journal’s podcast on Wednesday. However, Fauci refused to name certain states in particular. “It’s not for me to say because each state is different,” he explained. Three weeks ago, despite rapidly rising numbers, Fauci said, “I don’t think we’re going to be talking about going back to lockdown.” But the numbers have worsened since then. For example, as of July 9, there are almost 108,710 coronavirus cases in Arizona, 229,115 cases in Texas, and 223,775 cases in Florida, according to The New York Times data. And it seems citizens of these hard-hit states are in favor of such a drastic measure. In a recent Harris Poll conducted over the first weekend of July, 76 percent of citizens in both Arizona and Texas said they want their states to return to lockdown.
