The distinction between rhinitis and a cold primarily hinges on the following aspects: first and foremost, the specific onset time of the illness. Colds generally occur suddenly and last for a relatively short duration, about a week; whereas the duration of rhinitis may be longer, and some individuals might even experience chronic rhinitis, meaning the onset duration for rhinitis is relatively longer. The second aspect is the symptoms. Cold symptoms may include nasal congestion and a runny nose, but most patients will also exhibit other uncomfortable symptoms, such as sore throat, body aches, or fever. In the case of rhinitis, the primary symptoms are usually nasal, such as congestion, runny nose, and sneezing, and generally, there are rarely any whole-body symptoms. The third method is through an examination of the nasal cavity, which is primarily based on the doctor's experiential judgment. These three aspects essentially allow for the differentiation between rhinitis and a cold.
