This week, Virus Watcher published 273 surveillance posts, with no system alerts triggered. The most frequently monitored diseases included human rabies, influenza-like illness, avian influenza H5N1, imported measles, and Ebola. This period saw significant activity surrounding vaccine-preventable diseases and ongoing deadly outbreaks.
Measles outbreaks continued to be a major concern, particularly in the United States and Bangladesh. In Pennsylvania, a rapidly expanding outbreak has sickened over 670 people and is now linked to at least four deaths, making this the deadliest year for measles in the U.S. in decades. One of the latest fatalities was an unvaccinated 40-year-old woman. Meanwhile, Bangladesh is grappling with one of its worst public health crises, with a massive measles outbreak contributing to over 1,000 deaths since March 15, primarily among children, highlighting serious weaknesses in the country's immunization and healthcare systems.
The Democratic Republic of Congo (DRC) continues to battle its worst-ever Ebola outbreak. Authorities reported more than 7,000 cases, with the disease expanding into a seventh province, South-Ubangi, near Central Africa. Close to 3,500 people have died in this outbreak, with experts emphasizing the need for sustained resource mobilization for containment, though the government has suggested the spread may already have peaked.
Beyond measles and Ebola, other critical health threats emerged. A malaria outbreak near Frankfurt has resulted in eight total cases and three fatalities since August. In Mexico, a North Carolina teenager died from a rare brain infection caused by a microscopic amoeba, likely contracted from a community water feature. Australia is experiencing a surge in influenza cases, prompting warnings that it's not too late for vaccination.
Among the high-severity community alerts, a COVID-19 diagnosis was noted in Mecklenburg County, alongside the stark warning about the unvaccinated woman who died from measles complications in Pennsylvania. Admin-verified alerts also highlighted Sweden's record number of viral TBE infections and efforts to unblock sheep and goat exports in Romania.
