New York / New Jersey

Epidemiological Brief

New York/New Jersey's Santé signal is driven entirely by influenza A(H3N2), with combined bi-state weekly cases reaching 15,467 (New York: 12,564; New Jersey: 2,903) against the 52-week national maximum of 15,854—a normalized signal of 97.6/100, the highest influenza reading among all US host cities. Measles: 0 new cases in EW18 across both states (combined 4 YTD), indicating current outbreak suppression. Mpox: 0 new cases this week (combined 11 YTD). No hantavirus detections. The composite Santé score is 28.7 (low), reflecting the dilutive effect of a large four-disease denominator with only influenza elevated. Despite the low composite, public health planners should treat the near-peak influenza burden as a material operational risk at MetLife Stadium and other high-capacity indoor venues. Adequate antiviral stockpiles, rapid testing capacity, and ILI surveillance among venue staff should be pre-positioned. New York City's international hub status means continuous surveillance for measles importation remains essential. Sante Index v0 is a watching signal, not a forecast.
