Asthma appears to be significant risk factor in kids for severe H1N1: study
Parents of children with asthma should have an "increased state of alertness" about the pandemic flu virus, suggests the co-author of a new Canadian study comparing it to seasonal flu.
Asthma is a significant risk factor for kids who get the new H1N1 virus, compared to seasonal flu, the study indicates.
The work by researchers at Toronto's Hospital for Sick Children was released online Thursday by the Canadian Medical Association Journal. It is among the first publications on risk factors for children admitted to hospital with the pandemic H1N1 flu, which began circulating widely in people in the spring.
The study involved scrutinizing the charts of 58 youngsters admitted with swine flu from May 8 to July 22 this year, as well as the records of 200 kids with seasonal flu admitted from 2004 to 2009.
The data show that 22 per cent of kids admitted with H1N1 had asthma compared with six per cent of those admitted with seasonal influenza.
"Coming out of this study is the finding that children with asthma seem to be at a greater risk of ending up in hospital," said Dr. Upton Allen, chief of infectious diseases at the hospital and one of the authors of the study.
"It's a confirmation that asthma is a risk factor for severe infection due to influenza."
He said the findings should not alarm parents, but he indicated they should be vigilant.
