Falling asthma rates linked to lower levels of respiratory infections
Falling rates of asthma in the UK could be associated with lower levels of respiratory infections, UK researchers say
Between 1993 and 2000, the prevalence of asthma in the UK dropped, hospital admissions for the condition in the under 5s fell by 52% and primary care presentations in children under 14 years by over 40%, figures show.
At roughly the same time, primary care consultations for acute respiratory infections in all age groups fell by 36%, and for the common cold by 46%, and isolates for respiratory syncytial virus notified to the Health Protection Agency fell by 56%.
