The risks of getting rotavirus
Rotavirus is the most common cause of severe diarrhea in:
- young children
It causes more than 500,000 deaths worldwide in young children each year. Such deaths in Canada are very rare.
In Canada and other temperate regions, most rotavirus cases happen in late winter and early spring.
Rotavirus outbreaks have been reported among:
- hospitalized infants
- elderly people in nursing homes
- young children attending daycare centres
Severe rotavirus diarrhea among adults is rare in North America and occurs mostly in:
- the elderly
- those caring for children with severe rotavirus diarrhea
- those with weakened immune systems (unable to fight disease easily)
Who is most at risk
In general, unvaccinated children are at greatest risk of infection.
Children with weakened immune systems are more likely to suffer from severe rotavirus diarrhea that:
- is longer lasting
- can be fatal
Vaccinated children are much less likely to:
- get sick from rotavirus
- have severe symptoms
Even children who are vaccinated may get sick from rotavirus more than once.
