H5N1 has been confirmed in 27 Washington dairy herds. Pennsylvania has warned clinicians about congenital measles. The Ebola outbreak has passed 10,000 confirmed cases.
Influenza is off to an early start, with test positivity in the Pacific states growing quickly. Three Florida counties have declared states of emergency over dengue.

Measles; Cyclosporiasis: season totals; Naegleria fowleri: North Carolina and Louisiana; Chikungunya: Florida; Ebola: DRC past 6,000
A record cyclosporiasis outbreak keeps growing a month after the Taylor Farms recall, measles continues to circulate, and Ebola in DRC grows. Plus Covid, West Nile, Powassan, and dengue.
Cyclosporiasis outbreak linked to lettuce products. Measles passes 2025 high. NYC Legionnaires' cluster claims a 5th life. Ebola in DRC crosses 1,000 deaths.
The cyclosporiasis outbreak is on track to be the largest in U.S. history. Measles is on track to exceed 2025 totals. West Nile virus has an early season start.

Cyclosporiasis reports now exceed 3,300 nationwide, with Michigan hardest hit at 1,562, followed by New York (470) and Ohio (364). No source identified.
FOI Clinical issues two types of rapid communications: alerts for highest priority information, and advisories for emerging events clinicians should be aware of. This is an alert. Update July 13:
