Background on the Nationwide Diarrhea Parasite Outbreak
The current outbreak of Giardia lamblia was first identified in early March 2024, with initial cases reported in several states. The CDC began monitoring the situation as cases surged, especially in densely populated urban areas. Past outbreaks of similar parasites have been linked to contaminated water sources or food handling lapses, prompting swift investigations.
New York City, with its extensive water and food infrastructure, has historically faced challenges related to water safety, making it a prime candidate for the epicenter of this outbreak. The CDC and local agencies have increased testing and inspection efforts in response.
“We are working closely with federal partners to identify contamination sources and prevent further cases.”
