• Six more confirmed detections of New World screwworm (NWS) have been reported in Texas, bringing the total to 25, according to the latest update from the US Department of Agriculture’s Animal and Plant Health Inspection service. Five of the new cases are in sheep in Crockett and Edwards counties and one in cattle in Medina County. The Texas Animal Health Commission has placed parts of Medina County and two other counties under quarantine to prevent further spread of NWS flies and their larvae, which feed on the living tissue of warm-blooded animals, causing severe wounds. “Stopping the movement of infested animals and ensuring animals are moved safely is essential to limit the spread of NWS and reduce its impact on Texas,” the commission said. Three cases in the outbreak are now listed as inactive, including the one case detected in New Mexico.
• A Salmonella outbreak linked to alfalfa sprouted seeds has sickened 109 people in 11 European countries, with 18 hospitalizations and one confirmed death, the European Centre for Disease Prevention and Control (ECDC) reported yesterday. The affected countries are Austria, Belgium, Czechia, Denmark, Finland, Germany, Ireland, Luxembourg, Spain, the Netherland, and the United Kingdom. The ECDC says the link to alfalfa sprouts is supported by case-patient interviews, the detection of the outbreak strain in water used for growing sprouted seeds in the Netherlands and the United Kingdom, and epidemiologic links to a producer in Finland. Investigators have identified a common seed supplier in India and believe the seeds may have been contaminated before entering Europe.

Ethiopia reported its fifth case of circulating type 1 polio (cVDPV1) in 2026, while Laos reported its first two cVDPV1 cases of the year.

All but 12 of this year’s cases were locally acquired, with the rest related to travel outside the country.

Among all measles patients, 93% are unvaccinated or have unknown vaccine status.
