Children’s and young adults’ hospitalization rates are currently higher than those observed at this time in recent flu seasons, the CDC says, despite overall flu hospitalization rates staying around the same level. More than half of specimens that tested positive for influenza this season have been in people younger than 25.
Influenza B, which impacts young people more severely, has been reported more often this season on a national level, according to the CDC’s most recent flu-surveillance report. But influenza A’s H1N1 subtype has been more commonly reported in recent weeks.
