NSW Health flags probable Japanese encephalitis case as climate-driven spread grows

New South Wales Health says a probable Japanese encephalitis case is under investigation in a man in his 60s who was likely exposed in the Riverina region; JE has been detected in chickens used for early warning. While JE is usually mild, encephalitis can occur and has a case-fatality rate up to about 30%. Climate change is linked to the outbreak’s spread, and protection includes avoiding bites, using EPA-registered repellents, permethrin-treated clothing, and vaccines are available (free in high‑risk NSW areas for residents).

Colombia faces yellow fever surge as death toll surpasses 70

Colombia is grappling with a mosquito-borne yellow fever outbreak that has killed more than 70 people since 2024. The government declared a national health emergency last year; from 2024 to January 2026 there were 161 confirmed cases and 73 deaths, including 13 cases and 10 deaths in 2026. Yellow fever symptoms resemble flu—fever, headache and nausea—though severe cases can cause multi-organ failure and internal bleeding; about 15% of patients develop severe illness and roughly half of those die, according to the WHO. The outbreak is being monitored as part of global disease surveillance.

First Local Chikungunya Case in New York Since 2019

A case of chikungunya, a mosquito-borne virus typically seen in South America, has been confirmed in a Long Island resident, marking the first local transmission in New York since 2015. The virus causes symptoms like fever and joint pain, and while rare, severe cases can occur. The risk of transmission in New York is currently very low due to colder temperatures, but health officials advise precautions against mosquito bites. The increase in outbreaks globally is linked to climate change and urbanization.
