For how we live.
Mosquito-borne disease, health policy, and outbreaks across the continent.
Thirty-two interviews across Uruguay, Argentina, Chile and Mexico find implementation turned on governance, not software. A separate patent analysis shows where digital therapeutics are not being built.
Dust sampled inside 38 schools in Calama carried copper, arsenic, lead and molybdenum at levels that tracked the outdoor air — with almost no attenuation for arsenic and lead.
Among 17,508 notified cases from 2007 to 2021, 1.49% died of Chagas and 5.83% of other causes — with digestive complications, not cardiac ones, carrying the highest cumulative risk.
Only three of the 15 studies pooled in a Chilean meta-analysis used sleep testing at all. A Lima clinic analysis shows why that shortcut matters.
More than 410,000 probable cases so far in 2026, against 1.45 million for all of 2025. One state, Minas Gerais, accounts for roughly a sixth of the national case total on its own.
A national analysis of 2,985 haemorrhage deaths from 2015 to 2024 found no significant change over time — and Indigenous women dying at 2.87 times the rate of White women.
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.
A blinded comparison of 180 responses from a university telehealth centre in Minas Gerais found AI matched human specialists on medical adequacy and risk, and beat them on comprehensibility.
Peruvian Andeans are famous for high haemoglobin at altitude. A genome-wide scan finds the alleles under recent positive selection are the ones that lower it — a pattern closer to Tibetans than expected.
An analysis of 15 years of case data from Altamira, in the Xingu Basin, finds forest edge and local population size — not climate — explained where transmission returned.
Fine particulate exposure in seven Amazonian capitals was tied to about 5,472 circulatory and 2,621 respiratory deaths over six years. A separate analysis finds cardiac mortality rising with forest loss.
A comparison of FDA, EMA and ANVISA decisions from 2020 to 2024 finds Brazilian approvals arriving about a year later. A second study clocks the wait for public-system financing in years, not months.
A single-author analysis of Global Burden of Disease estimates finds the region's neurodevelopmental picture split in two — and argues the flat autism curve reflects diagnostic capacity, not risk.
Anvisa's five new resolutions build a controlled supply chain from seed to shelf, including a regulatory sandbox for patient associations. Analysts say the framework's biggest gap is the one it did not close.
The regional health agency counted 34 confirmed cases and 15 deaths in the first seven weeks of 2026, after 2025 brought the highest South American case total in over two decades.
PAHO counted 14,891 confirmed cases across the Americas in 2025, a 32-fold rise on 2024. Six South American countries reported cases, and only a third of the region's countries reach the coverage that stops outbreaks.
A national registry analysis found the highest burden among 20-to-29-year-olds and a notable rise among girls aged 10 to 19, with rates concentrated in the Sierra region.
A national pharmaceutical database analysis found out-of-pocket purchases accounted for 78-86% of contraceptive use, with emergency contraception priced up to 25 times higher than the insured rate.
Two November burden analyses put diabetes diagnosed before 40 on an upward path to 2050. In the Americas, Central Latin America carried the highest rates and men carried more of the burden than women.
Shared cell time raises transmission odds sharply — six months of it doubles them. But cell-level exposure explains only part of the genomic clustering, which undercuts contact tracing as a strategy.
A Buenos Aires surveillance cohort estimates 80.8% effectiveness against RSV hospitalisation in infants under three months — close to what the licensing trial found, in a real programme.
Age, sex, employment and socioeconomic level together explained under 1% of variance in insomnia severity. Perceived stress and generalised anxiety explained close to a third.
A WHO and Brazil special report released on the summit's Health Day says extreme heat kills over 540,000 people a year and that health facilities face 41% higher weather-damage risk than in 1990.
The 2025 Lancet Countdown Latin America report tracks 41 indicators across 17 countries. Heat-related deaths are up 103%, and fewer than half the region's governments have finished a vulnerability assessment.
A Brazilian randomised trial found laser and radiofrequency equally effective for genitourinary syndrome of menopause. The one trial that used sham treatment found no benefit at all.
ALEG's position holds that testosterone in postmenopausal women should be limited to hypoactive sexual desire disorder, and that pellets and compounded formulations are not recommended.
The causes recorded do not look like a textbook heat event: nonspecific findings, nervous system disease and mental disorders led the excess, and deaths at home rose 64%.
A study of 5,459 municipalities projects annual costs of $228-264 million by mid-century, with the largest absolute burden in the South and the fastest relative growth in the North.
