Toronto health officials say anyone who dined earlier this month at an upscale downtown Japanese restaurant should check themselves for symptoms of mumps after four staff at the eatery were infected with the virus.
Health officials say the employees didn't know they had mumps while working at Ki Restaurant, located on the corner of Bay and Wellington streets in Toronto's financial district.
Officials say anyone who ate at the restaurant between July 7 and July 18 is at a low risk of catching mumps.
The virus infects an average of 15 people a year in Toronto and is most commonly spread through saliva.
Symptoms of mumps include pain and swelling in salivary glands along the cheek and jaw, fever and loss of appetite as well as other signs.
Medical officer Dr. Irene Armstrong says anyone who has or thinks they have mumps should stay home for five days and not see visitors to make sure the infection doesn't spread.
The infection usually lasts about two weeks, meaning diners who may have contracted mumps at the restaurant would experience symptoms until Aug. 12 at the latest.
