Viral colds are contagious, so when a patient is diagnosed with a viral cold, he or she should be properly isolated, especially from the elderly, children and people with low immune function. When a cold is diagnosed, since the common causative agent is a virus, clinical treatment is mainly symptomatic, for example, if a patient has a fever, medication can be used to reduce the fever, or physical cooling methods. When a patient has a severe cough, he can take oral cough medicines, such as compound licorice tablets, strong loquat, Su Huang cough capsules, lung power cough combination, dextromethorphan, etc. When a patient has a significant sore throat, he can take Fatty Sea tablets. After the above treatment, if the patient’s symptoms are not significantly relieved, it is necessary to actively seek medical attention, further improve the relevant examination, and make further treatment.
