Norovirus at Olympics: Symptoms & Prevention

Olympic officials made the correct decision to postpone the Canada-Finland women’s hockey game on Thursday following a norovirus outbreak among players on the Finnish team, according to medical professionals. The swift action appears to have prevented further spread of the illness.

A Highly Contagious Threat

Dr. Nitin Mohan, a physician and epidemiologist at Western University in London, Ontario, described norovirus as “the sprinter of viruses,” emphasizing its rapid transmission rate. He commended officials for suspending the game, stating it “likely prevented a spread to the Canadian team.”

Did You Know? Switzerland’s women’s hockey team was also isolating in Milan on Friday after one of its players was diagnosed with norovirus.

Understanding Norovirus

Norovirus is a common cause of gastrointestinal illness, often referred to as “stomach flu.” Symptoms typically include the sudden onset of vomiting and/or diarrhea. Dr. Allison McGeer, an infectious disease specialist at Mount Sinai Hospital in Toronto, noted that in Britain, the illness is known as “winter vomiting disease.”

The duration of symptoms usually lasts between 24 to 36 hours, though some individuals may experience them for up to 48 hours. While unpleasant, most people will feel significantly better within a few days, though fatigue can linger.

How is it Spread?

Norovirus is highly contagious and spreads through contact with infected individuals, contaminated food, or touching contaminated surfaces. The virus can also be transmitted through aerosols released during vomiting, according to both Dr. Mohan and Dr. McGeer. Outbreaks are common in close-quarters environments like daycares and long-term care facilities.

Expert Insight: The Olympic environment, with its close proximity of athletes, communal dining, and stressful conditions, creates an ideal setting for the rapid spread of norovirus. Preventing outbreaks in such settings requires vigilance and swift action.

The Olympic setting, with its close contact and communal eating, is particularly conducive to the virus’s spread, compounded by the immune system suppression caused by the stressful environment. As Dr. Mohan stated, it’s “not all too surprising” that this has occurred.

Treatment and Prevention

There is no specific treatment for norovirus. The primary recommendation is to stay hydrated by drinking plenty of fluids, as vomiting and diarrhea can lead to dehydration. Rest is also crucial. Preventative measures include frequent handwashing with soap and water, though alcohol-based sanitizers can offer some benefit. Cleaning surfaces with bleach is also recommended.

Looking Ahead

Canada is scheduled to face Switzerland on Saturday. Given the recent norovirus case within the Swiss team, officials may need to closely monitor the health of players and consider further preventative measures to minimize the risk of additional infections. A possible next step could be increased testing and isolation protocols for all participating teams.
