China News Service, Guangzhou, August 15 (Reporter Cheng Jingwei) The National Clinical Research Center for Respiratory System Diseases recently held a seminar in Guangzhou with the theme of "10-year changes in the main allergens of asthma/rhinitis patients in China" in an online and offline manner. At the meeting, the research paper "Changes in the environment and sensitization of patients with allergic asthma/rhinitis in China from 2008 to 2018" was released.
According to reports, the research area covers 26 cities across the country, and a total of more than 5,000 allergic patients aged 5 to 65 years were included.

For the past 10 years, dust mites remained the most common allergen in people with rhinitis and asthma, he said.
He pointed out that in Chinese asthma and rhinitis patients, the sensitization rate of mites (house dust mites, dust mites and tropical mites), pollen (poplar, ragweed and mugwort) and animals (dog hair) increased significantly; In life, it is necessary to do a good job in the management of the home environment and natural environment to avoid the troubles to people's health caused by new allergens.
The results of the above study showed that there was an increase in fungal sensitization among Chinese children with asthma and rhinitis.
At the seminar, Liu Chuanhe, director of the Allergy Department of the Children's Hospital Affiliated to the Capital Institute of Pediatrics, said that according to the survey, the positive rate of allergens in children with rhinitis and asthma is generally higher than that of adults, and the positive rate of dust mites in particular is nearly double that of adults.
