For how we live.
A surveillance analysis of WHO data from January 2024 to February 2026 tracks the clade Ib emergency from declaration to its end, and finds reported spread continued after the emergency was formally lifted.

A national surveillance study found 415 children under 15 among Sierra Leone's 2024–2025 clade IIb mpox cases — three died, three-quarters needed hospital care, and household contact was the top documented exposure.
A 28-year-old technician at a plague research institute in Irkutsk died on 2 October. WHO rates the risk low in Russia and very low in Europe, but has asked Russian authorities to clarify the cause of her pneumonia.
Surveillance data show 252 locally acquired dengue cases in the Tampa Bay area by 26 September, 223 of them in Hillsborough County, where an 80-year-old woman has died. Three counties have declared emergencies.

A national analysis of 2020–2025 surveillance found a case fatality rate of 15.5% that never improved, a season tied to heat and rainfall, and a falling share of suspected cases ever confirmed.
A 2026 review reports more than 70 health facilities destroyed in North Kivu, 7.3 million people displaced and over 2 million children acutely malnourished, as conflict compounds overlapping outbreaks.
Trials show both new vaccines raise protective antibody levels in almost everyone. The unsettled question is the live-attenuated shot's safety in the older adults most likely to be hospitalised.
A 1,784-child randomised trial in Uganda found one-fifth and one-half doses of the 17DD vaccine matched the full dose for initial immunity — evidence for dose-sparing in young children when supplies run short.
The vaccines and antibody drugs that cut Ebola's death rate work against the Zaire species. None is approved for the Bundibugyo virus now driving the largest Ebola outbreak in Congo's history.
A vaccine given in 2017 still cut cholera risk 78% five years on, new data show — even as collapsing water and health services let the outbreak spread through Artibonite and Centre.

The agency stops short of calling 2025 a global surge. Its own regional tables show why: the Americas and the Indian Ocean drove the total while the Philippines and Malaysia reported fewer cases than last year.
Sequencing points to a fresh spillover from wildlife rather than a resurgence of the province's earlier outbreaks. Four of the dead are health-care workers.
WHO counted 409,222 cases and 4,738 deaths across 31 countries by 17 August. The divergence between the two trends is the finding, and it points at case management, not transmission.
Kerala's ninth Nipah outbreak since 2018 produced four unlinked cases between April and July, suggesting separate spillovers from bats rather than a chain of human transmission.
