On April 3, Alabama and Missouri issued orders closing nonessential businesses and requiring individuals to remain in their homes except for essential activities. Alabama’s order is in effect from April 4 through April 30. Missouri’s order is in effect from April 6 through April 24.

To date, 42 states have issued stay-at-home or shelter-in-place orders to residents. Of those 42 states, 24 have Democratic governors and 18 have Republican governors.

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