High transmissibility (R0 of 12-18) fuels spread in communities with vaccination coverage below the 95% herd immunity threshold, per WHO benchmarks. No federal epidemic designation, but case trajectory reflects waning MMR uptake post-COVID disruptions. Final CDC Morbidity and Mortality Weekly Report, expected early April, will confirm the March 31 tally after lab verifications; surveillance lags could adjust counts upward.",
