This week saw 304 surveillance posts published, with no system alerts triggered. The top reported diseases included cyclosporiasis, COVID-19, imported measles, Ebola, and confirmed novel influenza A virus infections.
Ebola continues to be a major concern, particularly in the Democratic Republic of Congo, where reports indicate over 2,000 confirmed deaths, making it the fastest-spreading outbreak on record. Health authorities are expanding their search for undetected infections, suggesting a potential increase in reported cases. Critical alerts related to Ebola were also issued, highlighting aid cuts exacerbating the situation and the presence of child coffins in Bunia.
Measles also saw significant attention, with Bangladesh reporting a rising death toll of 885 and over 1,000 new infections this week, bringing the total to over 156,000 cases since mid-March. High-priority alerts noted the U.S. recording the most measles cases in over three decades, with outbreaks spreading across multiple states.
Several high-priority outbreak events were flagged, including an unknown disease in Indonesia, where search and rescue teams are active following extensive destruction. Unidentified disease alerts were also raised for the U.S. Minor Outlying Islands, linked to Vibrio vulnificus deaths, and a general unknown disease alert impacting federal recommendations on vaccine schedules. Cholera in Angola was also noted as a substantial ongoing outbreak since January 2025. Vibrio vulnificus infections were specifically highlighted in top posts, with Louisiana reporting five deaths this year and Florida reporting two. A cholera outbreak was officially declared in Bauchi State, Nigeria, following lab confirmations and a surge in suspected cases across 13 Local Government Areas.
Admin-verified alerts emphasized several critical issues, including ongoing search and rescue efforts in Maumere (Indonesia) following the unknown disease event, concerns over health facility operational status in Sudan, and the appointment of a new Chief Executive Officer for a Nigerian infectious disease epidemiology professor. Other alerts touched upon pet abandonment fines in Chennai, regulatory challenges for complementary medicines in South Africa, and new smoking laws in South Africa.
