In the report “Vital Signs: Surveillance for Acute Flaccid Myelitis — United States, 2018,” on page 609, in the first paragraph of the Results section, the fourth sentence should have read “Patients with illnesses classified as non-AFM were significantly older than were patients with confirmed AFM (median = 8.8 years [range = 1 month–78.1 years]; p<0.001) (Table 1).”
On page 611, in Table 1, for “Laboratory finding; Spine MRI performed,” the number of confirmed cases should have been “233/233 (100),” and the P-value should have been “0.10.” In addition, for “Timing of preceding illness to onset of limb weakness, median days (range, IQR); Any respiratory illness,” the interquartile range (IQR) for noncases should have been “6.5 (0–28, 4–11.5).”
