On April 13, Tennessee Governor Bill Lee (R) extended the statewide stay-at-home order, called “safer at home” in Tennessee, that went into effect on March 31. The order was initially scheduled to expire on April 14, and will now remain in effect until April 30.

So far, 43 states have issued stay-at-home or shelter-in-place orders to residents. Although the names of the orders—shelter-in-place, stay-at-home, stay home, stay safe—vary from state to state, they include at least two common elements: the closure of nonessential businesses and requesting all residents to stay home except for essential trips.
