Abstract:
|
The current consensus is that children drive the spread of influenza epidemics. Studies have shown that children have high clinical attack rates, high social contact rates and play a major role in introducing influenza infections into the household. Using empirical data on the age, sex, city and date of laboratory confirmed cases of seasonal influenza A in Canada, the peak in incidence was identified 1 week earlier in persons aged 10-29 years than for other age groups. In the H1N1 seasons, infections occurred 1 week earlier on average among 10-19 year olds, while in H3N2 seasons, infections occurred on average 5 days earlier among young adults, aged 20-29 years. Higher within age-class transmission rates among high-school aged students may fuel the spread of influenza within the community; though young adults and working aged adults may introduce the virus into communities.
