Good day my son is 8 years old and still suffers with croup, my question is if he had to get the covid 19 virus would his croup condition make it worse for him?

Potentially : Croup is usually caused by a viral infection (often parainfluenza). An individual can have Croup in addition to a viral or a bacterial infection. Croup and COVID 19 are both respiratory infections but they target different areas.

Reduce airway edema: The use of steroids may be indicated to control his symptoms. Please keep him well hydrated, use cool air mist and monitor for fever and worsening respiratory distress.
