Upper Respiratory Infection (URI) is an infectious disease in one or more parts ranging from nasal airway to the lungs and takes place in less than 3 weeks. Upper Respiratory Infection (URI) is a contagious disease and is often experienced by children. Most of the URI is light, caused by a viral infection, and can heal themselves (self-limited diseases). However, URI also can be severe and cause death. Therefore we need to understand and properly handle the ISPA. We also need to know the signs of emergency in the URI so that our children are not too late to get treatment in hospital.
