Croup in the 21st Century

Monday night, my son's cold turned into a more serious 'barking' (and barfing) cough. The nurse, over the phone, said that it was probably Croup - which was confirmed by his doctor the next day. Evidently, it's not as bad as I remembered, especially after reading Mark Twain's Experience Of The McWilliamses With Membranous Croup which permanently placed the disease as a nightmare. Turns out "membranous croup" is what we now call Diphtheria. Oopsie.
