But now that states like Texas and Arizona are seeing alarming surges in reported cases of COVID-19, businesses large and small must decide whether to keep their doors open.

On Friday, Texas and Arizona shut down bars except for takeout and scaled back restaurant dining capacity.

However, many businesses had already taken those steps on their own, saying rising case numbers and shifting advice from state and local governments did not give them the confidence to stay open.

The CDC suggests businesses should immediately remove sick employees or customers and clean the immediate area after 24 hours, but it says the 24-hour wait is only “if feasible,” and can be shorter.

The most important thing for businesses to do, she said, is mitigate risks for employees by requiring masks, frequent hand-washing and physical distancing.
