Beijing, December 28 (Ma Shuaisha Guoxuan) Peng Zhibin, director of the Department of Respiratory Infectious Diseases of the Infectious Disease Management Department of the Chinese Center for Disease Control and Prevention, said in Beijing on the 28th that at present, the causative agent of respiratory diseases in China is mainly influenza virus, and most provinces have reached the peak of the influenza epidemic, and then there will be a gradual downward trend.
On the same day, the National Health Commission held a press conference to introduce the prevention and treatment of respiratory diseases in winter and health tips during the New Year's Day. Peng Zhibin said at the meeting that since the beginning of winter, there have been a variety of respiratory pathogens in China alternately or co-epidemic. At present, according to the monitoring results, the causative agent of respiratory diseases is mainly influenza virus, and most provinces have reached the peak of influenza epidemic, and then there will be a gradual downward trend. The activity of pathogens such as Mycoplasma pneumoniae, adenovirus, and respiratory syncytial showed low-level fluctuations. The incidence of new coronavirus infection is currently at a low level.
Peng Zhibin said that there are three main conditions for the epidemic of infectious diseases, including the source of infection, the route of transmission, and the susceptible population. Pathogens such as influenza virus, Mycoplasma pneumoniae, and adenovirus can be transmitted through respiratory droplets produced when a patient coughs or sneezes, and invades other susceptible populations, resulting in acute respiratory illness.
Peng Zhibin said that the climate is cold in winter, doors and windows are closed in most cases, and the air mobility is relatively poor. Most people work and live indoors, and their activities are relatively concentrated and have close contact, and once there is a source of infection, it is easy to cause the spread of pathogens. During the cold season, people's respiratory defenses also decrease, which is one of the reasons for the spread of respiratory infections in winter and spring. The elderly, children and other groups are also at a high incidence of respiratory diseases in winter and spring because of their low immunity. (ENDS).
