These symptoms appear within 4 to 5 days after infection. These may be the expression of a mild infection that can be managed at home or with the pediatrician's consultation
Sometimes RSV causes a more severe infection, leading to bronchiolitis and/or pneumonia. Symptoms of these complications may include:
- Breathing more rapidly than normal
- Skin under the chest, between the ribs or over the rib cage pulling in with every breath
- Coughing that is getting worse. A child may choke or vomit from intense coughing
- A highly pitched whistling noise while breathing
- A gray, mottled, or blue color to the skin (skin color changes in the fingernail beds or lips)
If the child shows any of these signs and has breathing difficulties, a professional should be seen immediately.
