County health types closed Fleming’s Steakhouse in Walnut Creek, California, Wednesday after confirming that the restaurant was the source of a norovirus outbreak that had made several diners ill earlier in the week.

An employee at the restaurant tested positive for norovirus.

Fleming’s Steakhouse will open Friday at 5 p.m. after getting a clean bill from the health department.

In January, a deli in Concord was closed because of norovirus.
