(Reporter Zhang Shuang and Zhou Xuejin from People's Daily Health Client) According to the daily pollen concentration monitoring data from the Pollen Research Laboratory of the Allergy Center of Beijing Century Memorial Hospital, the Beijing area has now entered the autumn pollen season.

On August 7, 2024 (the beginning of autumn), the amount of major allergenic pollen in Beijing is 38 grains per thousand square millimeters. The main allergenic pollens floating in the air are Humulus/Cannabis pollen at 18 grains per thousand square millimeters, Chenopodiaceae/Amaranthaceae pollen at 14 grains per thousand square millimeters, Poaceae pollen at 4 grains per thousand square millimeters, and Artemisia pollen at 2 grains per thousand square millimeters.

Not only in Beijing, but also in many places in the north, allergist and otolaryngologists told reporters from the People's Daily Health Client that after the beginning of autumn, the number of allergy patients seeking medical treatment has begun to increase.

"The increase in allergy cases is directly related to the amount of pollen. In the past two days, the number of outpatients has begun to rise significantly, reaching 250 to 260 people per day. According to past experience, when the pollen allergy peaks in autumn, the number of patients per day may reach 600." On August 10, Wang Xueyan, director of the Allergy Center of Beijing Century Memorial Hospital, told a reporter from People's Daily Health Client in an interview.

"After the beginning of autumn, most patients who come to the hospital suffer from allergic rhinitis, and most of them suffer from seasonal allergic rhinitis, also known as 'hay fever'." Zhou Kai, deputy chief physician of the Department of Otolaryngology at the Third Hospital of Xi'an, Shaanxi Province, added to reporters.

However, the situation is different in southern my country, especially in Guangdong. Li Shuo, chief physician of the Department of Otolaryngology at Shenzhen Union Hospital of Huazhong University of Science and Technology, told the reporter of People's Daily Health Client that since the allergens in these areas are mainly house dust mites and dust mites, the incidence of allergies does not fluctuate significantly throughout the year. "In the north, in addition to 'double mite' allergies, a large part of them are pollen allergies, so there will be obvious seasonal fluctuations."

Although there is no obvious difference in the symptoms of allergy patients in spring and autumn, Zhou Kai told reporters that the types of allergenic pollen vary in different seasons and regions, and the degree of allergic reaction induced by each type of pollen varies in different people. Therefore, even for the same patient, the severity of allergies in spring and autumn will be different.

Common symptoms of allergy patients include sneezing, runny nose, coughing and wheezing, which are easily confused with colds. Wang Xueyan said: "Allergy patients will have four obvious symptoms: itchy nose, stuffy nose, sneezing, runny nose, and more obvious itchy eyes. Colds generally do not cause severe itchy eyes." Not only that, more severe colds are also accompanied by fever, sore throat, etc., while allergies will not have such symptoms.

Regarding the prevention and treatment of pollen allergies, Li Shuo suggested that protective measures such as wearing masks and protective glasses should be taken one to two weeks in advance, and symptomatic medication should be taken in time. "For seasonal allergies, especially pollen allergies, timely medication is very important to control symptoms, avoid affecting the quality of life and causing more serious symptoms.complicationIf the symptoms are severe or last for a long time, it is recommended to undergo specific treatment under the guidance of a doctor.Immunotherapy, that is, desensitization treatment.
