For how we live.
In 544 pregnant women followed across Rio de Janeiro state, adverse maternal outcomes hit 18% of confirmed Oropouche infections versus 7% without, with fetal loss and haemorrhage risks roughly tripled.
A CDC field report documents the territory's largest dengue wave in over a decade, driven almost entirely by DENV-2, with one death — the first dengue-associated death there since 2005.
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.
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 single infusion of a pan-serotype monoclonal antibody cut viraemia and shortened fever in a 250-patient phase 2 trial in India — the first therapy to show preliminary efficacy against wild-type dengue in people.
Across 166,390 tests during Brazil's outbreak, two TAK-003 doses were 73% effective against symptomatic dengue and 88% against hospitalisation, with no sign of waning.
Italy logged 296 locally acquired cases in 2024, a European record. Transmission rose 19.8% per 1°C of warming, and modelling puts most of France in range for the mosquito that carries it this century.
A cluster-randomised trial in Cúcuta coated water containers in 13,803 homes. Dengue incidence fell to 337 per 100,000 versus 528 in control clusters, at about US$2 per household a year.
A rescreen of 1,000 acute febrile illness samples from Loreto found the virus circulating endemically rather than in a single outbreak, including in a remote riverine community.
A Brazilian laboratory study found both a prototype strain and an emergent reassortant killed neural progenitors and collapsed cortical structure. This is a dish, not a pregnancy.
Two 2026 papers describe the same shift: rural incidence now exceeds urban in some years, the peak has slid to October and November, and one in six hospitalised patients progressed to severe disease.
Guangdong recorded 25,335 local cases in 2025 — 98% of everything China has ever reported. Genomic analysis finds every Chinese outbreak lineage matching a recent import.
A CDC surveillance summary puts 2024 at 359% above the 2010–2023 annual average. The 2.8% that were locally acquired are the part that changes what mosquito control has to plan for.
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.
