Boston

Epidemiological Brief

Boston's epidemiological profile is dominated by moderate influenza A(H3N2) activity, with no other pathogens currently contributing meaningful signal. Massachusetts reported 9,821 weekly influenza cases in EW53 against a 52-week state peak of 15,854, yielding a normalized score of 61.9/100—one of the higher influenza readings among US host cities this week. Measles: 0 new cases in EW18 (0 YTD); Massachusetts remains measles-free in 2026. Mpox: 0 new cases this week (7 YTD). No hantavirus detections. The composite Santé score is 18.2 (low). Despite the low overall score, the near-mid-range influenza component reflects active H3N2 transmission across the greater Boston metro area. Fenway-adjacent venue health planning should ensure adequate respiratory illness management capacity, including antivirals for high-risk groups. Mpox background risk is low but ongoing; healthcare providers should maintain clinical awareness. Boston's academic medical infrastructure provides strong surge capacity should any unusual outbreak emerge during the tournament window. Sante Index v0 is a watching signal, not a forecast.
