Be clear, flu and the common cold are two different things.
(1) Different pathogens of infection: We refer to microorganisms that can cause diseases in people as pathogens. Influenza refers to the infection of people with specific influenza viruses, while the common cold is infected with more kinds of viruses than influenza.
(2) Different symptoms: The symptoms of the common cold are mainly reflected in the nose, such as nasal obstruction, runny nose and sneezing, while the symptoms of influenza are more and more complicated. In addition to nasal discomfort, there may also be abdominal pain, abdominal distension, vomiting, etc. In severe cases, respiratory failure or death may occur.
(3) Different transmission intensity: The transmission intensity of influenza is stronger, so once the flu is diagnosed, you need to ask for leave and do not go to work or go to school.
