Quebec's Ministry of Health and Social Services have reported 82 separate outbreaks of gastroenteritis across the province.
The majority of the cases are in health-care facilities, but two of the outbreaks are in two schools in different regions and seven of the cases are in daycares.
Public health Montreal medical officer Dr. Renée Paré says 26 cases of gastro have emerged in the city since September, and only in hospitals and long-term care facilities.
She said schools have not reported any outbreaks and are suggested to do so if one should occur, though the Health Ministry said schools don't have to report outbreaks and health care facilities do.
Neither the English Montreal School Board nor the Lester B. Pearson School Board have reported significant numbers of students coming in sick, but as it is still peak flu and gastro season, it is especially easy to catch it in schools.
"Schools are a place where a lot of little kids hang out, so it's not unreasonable that you would see (viruses) spread in facilities like that," said CJAD 800's health expert Dr. Mitch Shulman.
The viruses, he said, spreads very easily.
"The way they get into your system is through your hands. You touch something that's contimatined and inadvertantly either you're eating and it gets onto your food and into your mouth, or you rub your nose or your eyes and it gets into your body," he said.
Dr. Mitch says the best way to protect yourself from catching these viruses is by washing your hands.
If you or your child has already caught gastro or the flu, Dr. Mitch says it's important to stay hydrated.
