NewsPlague never disappeared, but modern medicine has changed the risk
Plague may sound like a disease from the history books, but Yersinia pestis still circulates in wildlife around the world. Despite recent concern over a possible laboratory-linked death in Russia, experts stress that human cases remain rare and the infection is usually treatable when diagnosed quickly.

NewsScientists map a hidden world of viruses across 102 cities
Cities are home to far more viral diversity than scientists previously realised. A global survey of nearly 3,000 samples from 102 cities identified almost 55,000 RNA virus species, most of them previously unknown, creating a new atlas of the viruses circulating through urban and peri-urban environments.

NewsEbola vaccine induces T cell cross-reactivity against Bundibugyo virus in humans
A vaccine developed against Ebola virus may offer some immune protection against the related Bundibugyo ebolavirus, for which no licensed vaccine currently exists. Researchers found that a single dose triggered T cells capable of recognising BDBV, raising the possibility that existing vaccines could provide a degree of cross-protection during outbreaks.

NewsCholera cases surge as conflict in Yemen displaces over 200 000 people
Escalating conflict and mass displacement in Yemen are increasing the risk of infectious disease outbreaks as overcrowding, inadequate access to safe water and disrupted health services expose growing numbers of people to cholera, measles and other preventable diseases.

NewsWHO welcomes adoption of United Nations political declaration on pandemic prevention, preparedness and response
The World Health Organization (WHO) has welcomed the adoption by the United Nations General Assembly (UNGA) of the Political declaration on pandemic prevention, preparedness and response (PPPR).

NewsWHO Pandemic Hub sets ambitious goal to detect new outbreaks within 24 hours
The WHO has launched a new five-year strategy aimed at helping every country detect and understand emerging health threats within 24 hours by 2030. The plan combines AI, genomic surveillance, modelling and international data-sharing to help stop outbreaks before they grow into wider epidemics or pandemics.

News‘Molecular movie’ captures penicillin being built atom by atom
Scientists have captured the formation of penicillin’s defining β-lactam ring in unprecedented detail, revealing fleeting chemical steps that had remained hidden for decades. Using ultrafast X-ray imaging, the researchers built a molecular movie of the reaction that could help guide future antibiotic and enzyme design.

NewsMalaria remains the leading cause of hospital admission and in-hospital death in children under two in Sierra Leone
Malaria remains the biggest threat to young children in Sierra Leone, accounting for more than half of hospital admissions in a large two-year study. Researchers also found that children who received all routine vaccinations and preventive malaria treatment had a substantially lower risk of dying.

NewsNon-profit offers new front in the fight against pandemics
From AI-powered disease detection to stronger global health networks, Eric and Wendy Schmidt launch a new nonprofit to help the world identify emerging threats and respond before outbreaks escalate.

NewsFrom warning signals to action: Closing a critical gap in infectious disease preparedness
Between the first sign of an unusual event and an effective public health response lie several critical steps: verifying the signal, identifying the pathogen, assessing the risk, making a decision, and translating that decision into action. A new Perspective asks: how can infectious disease risk assessment better support timely and actionable public health decisions?

NewsValue-aligned messages increased COVID-19 vaccination intentions, study finds
Vaccine-hesitant adults were more likely to consider getting a COVID-19 vaccine when public health messages acknowledged distrust of government and affirmed values such as personal liberty, a new study found.

NewsA newly discovered membrane defence help explain antibiotic resistance in Pseudomonas aeruginosa
Scientists have uncovered how Pseudomonas aeruginosa, a major multidrug-resistant superbug, helps block antibiotics from entering its cells. The study identifies two proteins that act like plugs inside a membrane channel, revealing a potential new target for treatments designed to weaken bacterial defenses.

NewsPooling samples could expand TB testing worldwide
Testing sputum samples in small groups could nearly double access to rapid tuberculosis diagnosis without doubling costs. The largest study of pooled TB testing found that the approach cut molecular test cartridge use by 51%, helping inform new WHO guidance for resource-constrained settings.

NewsWhat makes hantaviruses jump from rodents to humans?
Why do some hantaviruses jump from rodents to humans while others remain largely confined to wildlife? A new study will combine viral genetics, climate data and wildlife ecology to uncover the conditions that drive spillover and help identify where future outbreaks are most likely to emerge.

NewsA ‘society on a chip’ reveals how viruses spread
Researchers have built a centimetre-scale ‘society on a chip’ that recreates how viruses spread through structured populations. By changing cell density, susceptibility and movement, the platform can mimic transmission, social distancing and even herd-immunity-like effects in real time.

NewsGlobal study finds stark differences in RSV vaccine uptake
Vaccination against respiratory syncytial virus during pregnancy lowers the risk of severe disease in babies by 74 per cent, but uptake in many countries remains low, according to a review revealing evidence of lower uptake among some socioeconomic and ethnic groups, those with reduced access to healthcare, and mothers of a younger age.

NewsMaternal vaccines protect babies from serious infections, but unequal access limits benefits across Europe
Europe must act now to strengthen maternal vaccination in pregnancy and ensure all women and babies can benefit from a new generation of vaccines to protect against serious infections, says a new series being launched today.

NewsResearchers built a low-cost system that knows when coughing is on the rise
What if a room could tell when coughing is on the rise without cameras or identifying anyone? Researchers have developed a low-cost sensor system that uses microphones, AI and lightweight computing to count coughs and distinguish between different coughers, potentially helping hospitals spot increases in respiratory illness earlier.

NewsUganda launches Phase I clinical study of Bundibugyo virus disease vaccine
A Phase I clinical study has been launched evaluating the safety and immunogenicity of a candidate vaccine against Bundibugyo virus disease (BVD), a severe form of Ebola virus disease caused by Bundibugyo virus (BDBV). The study is part of an international effort to develop vaccines against Ebola virus species for which no licensed vaccines are currently available.

NewsChiba University and Noguchi Memorial Institute for Medical Research partnership targets next-generation vaccines
Chiba University and the University of Ghana’s Noguchi Memorial Institute for Medical Research have launched a new research partnership aimed at advancing next-generation vaccines, therapeutics and diagnostics. The collaboration will connect expertise in Japan and Ghana to strengthen infectious disease research, researcher training and global health innovation.
