I’m an epidemiologist and associate professor at Johns Hopkins, where I direct the Center for Outbreak Response Innovation. I have a PhD and an MPH. My book, Crisis Averted: The Hidden Science of Fighting Outbreaks was published by Viking in 2024.
U.S. measles passes 3,000 cases for the first time since 1991. Cyclosporiasis totals climb after the season closed, a sprout recall widens, Covid-19 rises in 47 states, and DRC's Ebola response misses nearly every target.
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.
The cyclosporiasis outbreak may be older than previously understood
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:
Grand Canyon mystery illness spreading among Colorado River rafters (5+ groups, no dx). DRC Ebola accelerating past 1,580 cases; first-ever Bundibugyo treatment trial launches. Uganda adds separate Marburg case. NYC Legionnaires cluster hits 18. Tularemia treatment guidance updated.
The Ebola outbreak is now the third-largest on record. A Cyclospora outbreak has sickened at least 145 people across nearly 20 states, no food source identified. A second infant formula botulism outbreak has been traced to the same milk supply chain implicated in last year's ByHeart recall.
The Ebola outbreak surged past 800 confirmed cases in DRC, with Africa CDC warning it could become the worst Ebola outbreak in history. The World Cup's first week saw more heat casualties than infectious disease, while summer enteric pathogens accelerate domestically.
The FIFA World Cup opens tomorrow with 6.5 million fans arriving across 16 cities. The Bundibugyo Ebola outbreak surges past 550 confirmed cases in DRC, with CDC modeling warning of 20,000+ cases within three months.
