Sneezing is not necessarily a new type of pneumonia infection. Late winter and early spring are the high season for respiratory infections every year, as well as the high incidence of the common cold and flu. The common cold usually presents with obvious upper respiratory symptoms such as sneezing, runny nose and throat discomfort, with mild systemic symptoms and no fever or only a brief fever. Therefore the presence of sneezing is not necessarily a new type of pneumonia infection. In addition, it is recommended to develop the habit of covering the mouth and nose with a tissue or elbow sleeve when sneezing or coughing, rather than covering them with your hands, to reduce the spread of germs.
