Viral colds, known as “seasonal colds (colds caused by seasonal viruses, which are contagious, i.e. influenza)” in Chinese medicine, differ from wind-cold and wind-heat colds in terms of onset, prevalence, and progression of the disease. 1. Time of onset: Wind-cold, wind-heat and wind-heat colds occur at the time of climate change and are seasonal in nature, while seasonal colds can occur in all seasons and are not seasonal. 2. Prevalence: Wind-cold and wind-heat colds do not have any obvious prevalence characteristics, while seasonal colds are prevalent. 3. Disease development: wind-cold and wind-heat colds are mild, and if they cannot be cured for more than a week and the fever does not subside or worsens, it should be considered whether they are secondary to other diseases; whereas seasonal colds have a rapid onset and change, and other changes are likely to occur if the treatment is not timely and the disease is more serious. Whether you are infected with wind-cold, wind-heat or seasonal colds, you should consult a doctor in a timely manner and seek treatment under the guidance of a professional doctor to avoid delaying your condition.
