The prevalence of pollen allergies among adults in Sweden has increased. However, the prevalence of allergies to furred animals, mites or mold has not. These were the results of a new study at Sahlgrenska Academy.
The prevalence of allergic diseases has increased since the mid-1900s, and today, approximately one fourth of Swedish adults has hayfever, while 10 percent suffer from asthma.
Asthma and hayfever are strongly linked to allergic sensitization, that is the prevalence of antibodies against allergens, for example, from pollen or furred animals.
