[Health Channel/Comprehensive Report]As autumn and winter arrive, will the virus become more rampant? Huang Xuan, a thoracic and critical care specialist, said that autumn and winter are the seasons for viral infections. According to research, the infectivity and severe mortality of respiratory diseases will increase in autumn and winter, especially Wuhan pneumonia (novel coronavirus disease, COVID-19), Influenza and Respiratory Syndrome Virus (RSV) viruses, etc., therefore, it is called that the Wuhan lung vaccine booster dose and influenza vaccine are still the best prevention tools in autumn and winter.

Huang Xuan’s Facebook fan page “Dr. Ooi Hean“The article pointed out that an article published in “Lausanne Frontier Voice“(Frontiers) research found that because in cold weather, people tend to stay indoors and the air circulation is poor, thereby increasing the risk of respiratory disease transmission; and the air in winter is drier than in summer, causing the respiratory mucosa to become dry. , susceptible to viruses and bacteria.

Huang Xuan said that Wuhan pneumonia, influenza and RSV viruses are all likely to co-circulate in this autumn and winter. According to the World Health Organization (WHO), the use of booster doses of Wuhan pneumonia vaccine and influenza vaccine is still low; it is still far from achieving the annual influenza vaccine coverage target of 75% for high-risk groups set by WHO. , it is expected that with the coming of autumn and winter, whether it is Wuhan pneumonia or influenza, it may also spread significantly.

Wu Lung is not only infected in autumn and winter

Huang Xuan emphasized that although many people think that Wuhan pneumonia will be the same as seasonal influenza, there is currently no consensus that Wuhan pneumonia is not a virus that only spreads seasonally. Because there are always new mutations of Wuhan pneumonia virus, but the media did not report it extensively, everyone thought that the virus had disappeared; in addition, researchers further found that in cold climates, since the emergence of new severe acute respiratory syndrome Wu Lung, respiratory tract infection infectivity and mortality seem to be stronger, especially in high latitudes, the seasonality of Wu Lung is more obvious, mainly because it is too dry and cold, which is very suitable for many respiratory viruses to survive.
