Etymologically, the entry records: From acute + flaccid + myelitis. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is acute flaccid myelitis, spelled A-C-U-T-E- -F-L-A-C-C-I-D- -M-Y-E-L-I-T-I-S, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
