Zhongxin Wanghai, May 5 (Chen Jing, Xu Lanqing) Recently, many patients with upper respiratory tract infections with acute pharyngitis symptoms have visited the hospital. Liu Danwei, chief physician of the Department of Respiratory Medicine of Shanghai Medical University Hospital, pointed out in an interview on the 19th: "Among these patients, most of them are laryngitis caused by the common cold, a small part is laryngitis caused by influenza, and a small number are indeed due to new crown infection." ”

Liu Danwei introduced that the upper respiratory tract and throat are the gateway of the human body, whether it is influenza virus, new coronavirus, or bacterial infection, it may cause sore throat. Attention should be paid to identification, differentiated treatment, and symptomatic standard treatment. "The sore throat feels the same as the sore throat after "yang" before. Mr. Wang, who came to the hospital, said that because he suspected that he was "two yang", he took a nucleic acid test, and the result was negative. After inquiring, the doctor learned that after the "May Day" holiday, Mr. Wang has been working overtime, staying up late, and eating a late-night snack in the evening.

Liu Danwei introduced that the main symptoms of such patients include dry itchy throat, foreign body sensation, sore throat, etc., and when inflammation invades the larynx, cough and hoarseness symptoms may also occur. Why has the number of people with strep throat increased recently? Liu Danwei said that during the seasonal virus transmission period, overwork, neglect of dietary hygiene, personal hygiene, and immune disorders may be recruited.

Is a sore throat "two yang"? The expert said: 80% of sore throat is caused by viral infections, such as influenza virus, new coronavirus, respiratory syncytial virus, adenovirus, etc.; However, in addition to viruses, strep throat can also be caused by bacteria or stimuli such as dust and smoke, or allergic rhinitis, gastroesophageal reflux disease, etc. Therefore, relying only on the single symptom of sore throat, it is impossible to judge whether it is "two yang". If symptoms such as fever, cough, and body aches occur at the same time, a new crown antigen test can be performed: if the test result is positive, you should pay attention to self-isolation and go to the hospital.

Hu Bijie, director of the Department of Infectious Diseases of Zhongshan Hospital affiliated to Fudan University, said: According to clinical observations, the population with secondary infection is generally milder than the symptoms of the first infection, mainly manifested as fever and sore throat.

In the interview, Liu Danwei reminded the public: it is necessary to adhere to good personal hygiene habits such as hand hygiene and frequent ventilation, insist on wearing masks, and do a good job in personal protection; Rarely to places where many people gather, keep the air clear; Strengthen physical exercise, strengthen nutrition, enhance one's own immunity, help reduce the risk of transmission, and prevent and treat various infectious diseases.
