Answer

Infection with influenza A is associated with severe respiratory disease, as it has been detected in children with marked respiratory compromise. The bacterial pathogen, Mycoplasma pneumoniae, has also been identified in a few cases of croup. [5] Prior to 1970, diphtheria, also known as membranous croup, was a common cause of croup-like symptoms. Vaccine coverage for diphtheria has eliminated this infection with no case reported in the United States for decades.
