Boston

Epidemiological Brief

Boston carries a LOW epidemic risk score (22.5), with influenza as the predominant active component alongside modest measles and pertussis activity. Influenza ILI% of 11.7% reflects late-season transmission persisting in Massachusetts. Measles incidence of 0.1 per 100,000 is low but not negligible given the potential for importation amplification in stadium settings. Pertussis (1.0 per 100,000) and mpox (0.07 per 100,000) contribute minor signals. Dengue incidence is very low. Gillette Stadium's lower-risk profile does not eliminate the need for basic public health preparedness. Massachusetts DPH should maintain active case-based surveillance linkages and ensure venue medical staff can manage febrile respiratory illness triage. Visitors with documented influenza vaccine refusal or incomplete MMR records should be encouraged to update immunisations before attending. Event medical teams should carry rapid influenza A/B diagnostics and antiviral medication stocks. The relatively low overall risk makes Boston one of the safer venues, though vigilance for imported cases from higher-risk co-host cities remains important.
