Spring colds and fevers can be caused by large temperature differences, dry air and viral infections.
1. Wide temperature difference: The temperature difference between morning and evening in spring is relatively large, usually if you do not pay attention to increase or decrease the clothes, resulting in cold or hot, it will cause cold and fever.
2. Dry air: the air is dry in spring, if you drink less water, the mucous membrane of the respiratory tract is dry, which will easily lead to cold and fever.
3. Viral infections: common rhinovirus, respiratory syncytial virus and so on. The above mentioned pathogenic bacteria multiply in large quantities in the respiratory mucosa when the body’s resistance drops, causing damage to the respiratory mucosa and a large amount of inflammatory mediators into the bloodstream, leading to fever in patients.
Spring cold and fever should go to the hospital in time, under the guidance of the doctor to identify the cause of active treatment, so as not to delay the condition.
