Recently, a piece of news has become a hot topic, "More than 10,000 cases of new coronavirus infection in Guangdong have been added." Is it possible that respiratory diseases such as the new coronavirus are about to make a comeback?

Understanding Respiratory Diseases

First, we need to understand how respiratory diseases are spread. Most respiratory diseases are spread through airborne droplets, such as those released when coughing or sneezing, or by contact with surfaces contaminated with pathogens.

Respiratory diseases re-emerge at the turn of summer and autumn

At the turn of summer and autumn, the daytime may still be hot, while the temperature at night will drop significantly. This large temperature difference between day and night may lead to a decrease in human immunity, weakening the defense function of the respiratory mucosa, making it more vulnerable to virus and bacteria.

Secondly, the humidity is higher in summer, while it is relatively lower in autumn. Dry air can cause the respiratory mucosa to lose moisture, become dry and fragile, and thus reduce the defense against pathogens. In addition, the use of air conditioning can increase the difference in humidity between indoors and outdoors, and being in a dry environment for a long time can easily cause respiratory discomfort.
