Cold, commonly known as "cold", also known as acute rhinitis or upper respiratory mucositis, is mainly caused by rhinovirus, followed by coronavirus, respiratory syncytial virus, echovirus and Coxsackie virus. The onset is relatively acute, and the incubation period ranges from 1 day to 3 days, depending on the virus, enterovirus, adenovirus and respiratory syncytial virus.

The main symptoms are nasal symptoms, such as sneezing, stuffy nose, runny nose, cough, dry throat, itchy throat or burning sensation, and even a feeling of dripping after nose. Symptoms such as sneezing, stuffy nose and runny nose can occur at the same time or several hours after onset. After 2~3 days, the runny nose thickens, often accompanied by sore throat, tears, hypofunction, dyspnea, hoarseness and so on. Generally speaking, there is no fever and systemic symptoms, or only low fever, discomfort, mild chills and headache.

Physical examination found congestion, edema, increased secretion of nasal mucosa and mild congestion of throat. Inflammation of the eustachian tube may lead to hearing loss and other symptoms. Severe symptoms of purulent sputum or lower respiratory tract indicate that besides rhinovirus or secondary bacterial infection, other virus infections should be combined. If there are no complications, it can be cured within 5~7 days. Acute viral pharyngitis is mainly caused by rhinovirus, adenovirus, enterovirus and respiratory syncytial virus. The clinical manifestations are itchy or burning throat, rare cough and inconspicuous sore throat. Streptococcus infection usually occurs when swallowing pain. Adenovirus infection can cause fever and fatigue.
