Are your friends and family suddenly coming down with a stomach bug? Across Canada, health officials are warning of an increase in norovirus cases. Here’s what Dr. Jerome Leis, medical director of Infection Prevention and Control at Sunnybrook, wants you to know about norovirus and how to protect yourself from it.
What is norovirus?
Norovirus is a highly contagious stomach illness that causes vomiting, diarrhea and stomach pains, that usually resolve in 12-72 hours. Sometimes referred to as the “winter vomiting disease,” norovirus is common in the cold winter months, when people are spending more time inside, in closer contact with each other.
How does norovirus spread?
The virus is spread through infected fecal matter that gets ingested into the mouth. The virus can survive on surfaces like door handles, sinks or tables which people can unknowingly touch.
The virus can also spread through food and drink. Individuals may contract the virus after sharing food or drinks or eating food prepared by someone infected with norovirus.
Some raw shellfish like oysters or shrimp, can become contaminated with norovirus through the water, which can later be ingested if not properly cooked.
How can I protect myself from norovirus?
Frequently washing your hands with soap and water after going to the bathroom, before eating or preparing food or taking medications is the most effective way to prevent norovirus.
You should also frequently wipe down shared surfaces like handles, sinks, tables and cooking surfaces.
Be mindful of sharing food with others, or settings like potlucks, where food can easily become contaminated with norovirus.
