The order began at 5 p.m. Saturday and will go until April 7. Like other states, the order will mean residents can still go to the grocery stores, put gas in their cars, take walks outside and make pharmacy runs.

But, what else qualifies as an essential business?

Here's a rundown, from The News Gazette:

The list of businesses and organizations that will be allowed to remain open under the terms of Gov. J.B. Pritzker’s stay-at-home order is far lengthier than the ones that shut down effective 5 p.m. Saturday.

Licensed day care homes for up to 12 children will be closed but may reopen as an unlicensed day care home for up to 6 children."
