Most common cold in children are caused by viral infections.
In addition to the fever itself caused by the infection, respiratory viral infections may trigger a chain reactions of wheezing and acute attacks of asthma in young children and other relatively rare problems such as myocarditis and autoimmune diseases.
But the most common and longest lasting symptom is cough.
According to some studies, about 30-40% of patients with cold develop a cough, which peaking on the 5th day of the cold and lasting about 2 weeks.
If a cough persists for a long period of time, which of more than 10 days, and is accompanied by symptoms such as runny nose, fever, and increased breathing rate, parents need to be alert and take their children to the hospital in time.
If diseases that need to be intervened or treated, such as pneumonia or sinusitis, are ruled out, the cough itself is a defensive reflex used by the body to clear the respiratory tract. It is not a cough that leads to pneumonia, so parents need not worry too much.
