Rising measles cases in unvaccinated communities, particularly a Chicago migrant shelter outbreak with over 60 confirmed infections, have driven trader sentiment toward higher totals by March 31. The CDC reports 102 confirmed U.S. cases year-to-date as of March 28 across 16 jurisdictions, up sharply from 35 at February's end, fueled by declining vaccination rates below the 95% herd immunity threshold and importation from endemic regions. Incubation periods of 7-21 days mean recent exposures could still yield diagnoses before quarter-end; watch the CDC's weekly update around April 4 for final tallies. Historical baselines show rare large outbreaks without sustained transmission, but current R0 of 12-18 underscores rapid spread risk if unchecked.
