Weekly cases reported to CDC's National Notifiable Diseases Surveillance System, 2025 to present.

Counts are provisional, and occasional one-week troughs are incomplete reporting rather than real drops.
Active multistate outbreak investigations CDC has issued a notice for. These are national and do not change with the state selected above — CDC counts cases by state but publishes each investigation as one multistate notice. Every figure is CDC's own, copied from the notice each row links to; nothing here is derived.
Company announcements FDA has posted across all the products it regulates — food, drugs, devices and cosmetics — newest first. These are national and do not change with the state selected above. Each summary is FDA's own opening wording.
