Most of the kids who died were unvaccinated, and about half had no underlying health conditions.
Decisions about investing in building wastewater surveillance capacity should consider the vast economic and social cost of responding to infectious diseases not detected and arrested early, the authors say.
The findings suggest that antivirals may shorten hospital stays, cut the risk of infection in high-risk patients, and lower the risk of death when begun early.
Dominant flu strain varied by subregion, and a few countries, such as Chile and Zambia, reported very high activity.
US health officials are eying ways to reduce the spread of the virus over colder months and the holiday season.
