Your child may have one or more of the following symptoms:
- Cold-like symptoms
- A dry, hacking cough with no mucus. This is called a non-productive cough, and it may be worse at night. The cough may become productive (with mucus) in two to three days.
- Fever (temperature over 100.3°F)
- Not feeling hungry
- Inconsolable (cannot be calmed for at least a few minutes each hour using methods that usually work for your child, such as holding, rocking, pacifiers or soothing talk).
