WEEKLY REPORT
Evaluation of a Combined Text Messaging and Online Survey Protocol for Giardiasis Case Investigation — Colorado, September 2023–May 2024
Among 564 laboratory-confirmed Giardia cases in Colorado, 305 were invited by text message to participate in an online case investigation survey and 95 (31%) completed it. The effort enabled public health investigators to rapidly contact people with infection using fewer resources than needed for telephone interviews.
Notes from the Field: Early-Season Human Plague Transmitted from an Infected Cat — Oregon, January 2024CDC’s Division of Vector-Borne Diseases’ Diagnostic and Reference Laboratory confirmed the presence of Yersinia pestis (plague) in a pet cat in Oregon through PCR and culture testing. The cat transmitted Y. pestis to its owner before dying in January 2024. The case occurred earlier in the calendar year (January) than the other 18 cases reported in Oregon during the previous 90 years, with other cases typically reported May–August.

Waterborne Disease Outbreaks Associated with Splash Pads — United States, 1997–2022
Two-thirds of waterborne disease outbreaks associated with splash pads during 1997-2022 were linked to Cryptosporidium. The most frequently reported contributing factors to Cryptosporidium-associated outbreaks included children going in splash pads when sick with diarrhea or accidentally pooping or vomiting in the water.
Shiga Toxin–Producing Escherichia coli O157:H7 Illness Outbreak Associated with Untreated, Pressurized, Municipal Irrigation Water — Utah, 2023
In 2023, at least 13 children in Utah became ill during an outbreak of Shiga toxin–producing Escherichia coli O157:H7 associated with untreated, pressurized, municipal irrigation water.
