Researchers developed a needle-free spray-mist device to push last-resort antibiotics through the skin into infected tissue. The method aims to treat drug-resistant infections while reducing organ damage linked to intravenous delivery.
Yale researchers imaged the molecular structure of Vibrio cholerae flagella in living bacteria. The study shows how flagella proteins sit inside a hydrophilic sheath and suggests the sheath helps the bacterium move and infect cells.
A study found that adults hospitalised with respiratory syncytial virus (RSV) often had lasting problems. Many patients experienced breathlessness and trouble with daily activities for months, and some stayed unwell for up to a year.
Researchers presented four new AI approaches for detecting and monitoring TB at the Union World Conference on Lung Health in Copenhagen (18–21 November). The tools include breath analysis, cough screening, vulnerability mapping and a chest X‑ray tool for children.
PAHO has published the first evidence-based guide to treat tungiasis, recommending low-viscosity dimethicone and warning against unsafe manual removal. The disease affects millions in Latin America, the Caribbean and Sub-Saharan Africa.
Rwanda reported a second Rift Valley Fever outbreak near the Tanzania border and has increased surveillance and livestock vaccination. Officials say lack of rapid diagnostic tests slows detection, while a human vaccine candidate enters Phase II trials.
