I have 2 kids aged 2.5 and 1 year old for the past 2 mnths they are getting fever cold and cough again and again. What is the reason is they are having any infection. What is the cause please suggest

A. Most colds are caused by rhinoviruses. Your child can catch a cold through airborne droplets from or through direct contact with a sick person. Sneezing, coughing, and a runny nose are common symptoms.
