Pertussis admissions linked to asthma

ASTHMA is a leading risk factor propelling older children with pertussis into hospital, a Sydney study shows.

Dr Helen Quinn (PhD), research fellow at the National Centre for Immunisation Research and Surveillance, has found that while children older than 12 months who contract pertussis are often treated in the emergency department, those with comorbidities tend to be admitted.

In a study of 519 laboratory-confirmed pertussis cases, including 296 admitted to the Children’s Hospital at Westmead, Sydney, from 2007 to 2012, Dr Quinn found most of the patients older than 12 months were fully vaccinated.
