This study is testing a finger-prick blood test called FebriDx in 800 children aged 2-11 who have a fever and symptoms of a respiratory infection. The goal is to see if the test can quickly tell whether the infection is caused by bacteria or something else (like a virus). If accu…

This study aims to create and test a clinical prediction score called FUNGAL-P to help doctors identify fungal pneumonia early in adults who come to the hospital with pneumonia. Researchers will analyze medical records from past patients and then test the score on new patients to…

This study tests a new technology called Pictura Bio that aims to detect respiratory viruses quickly and cheaply from nose or throat swabs. Researchers will collect samples from 1000 adults and children with suspected viral infections at a UK hospital. The data will be used to tr…

This study is testing new rapid tests (lateral flow and microfluidic devices) to detect respiratory infections in children and adults in Uganda, Ethiopia, and Senegal. Researchers want to see if these tests are accurate and easy to use in low-resource clinics. Participants with r…

This study is testing a new diagnostic tool that helps doctors quickly tell if a respiratory infection is caused by bacteria or a virus. The goal is to see if using this test leads to better treatment decisions, fewer unnecessary antibiotics, and lower healthcare costs. About 100…

This study tests whether adding a special breathing treatment called intrapulmonary percussive ventilation (IPV) to standard care helps patients with pneumonia who are on a breathing machine. About 96 adults will be randomly assigned to receive either standard therapy alone or st…

This study looks at whether children with pneumonia caused by Mycoplasma bacteria need antibiotics to get better. About 376 children aged 3-17 will receive either a placebo (inactive pill) or a common antibiotic. Researchers will track how long symptoms like fever and fast breath…

This study gathers fluid and tissue from the lungs and nose of healthy volunteers and people with a history of lung infections. Researchers will compare samples to find differences in immune function that might explain why some people are more prone to infections. Participants un…

This study aims to identify the types of fungi causing pneumonia in immunocompromised ICU patients and test how resistant they are to antifungal drugs. Researchers will collect samples from 250 adults in intensive care who have pneumonia that does not respond to antibiotics. The …

This study will collect medical information and samples from 300 cancer patients who have or are at risk for a serious fungal infection called mucormycosis. Researchers hope to learn more about how the infection develops and how to better diagnose and manage it. Participants will…

This study tracks respiratory infections in thousands of patients across China to build a better early warning system. Researchers collect routine medical data and samples to identify which germs are circulating and how the body responds. The goal is to help hospitals and health …

This study tests whether implementing new Swiss national guidelines for acute respiratory infections can reduce unnecessary antibiotic prescribing in primary care. Researchers will work with 200 family doctors in quality circles and walk-in clinics, providing training and materia…

This study looks at 790 adults with S. maltophilia infections, a hard-to-treat bacteria. Researchers will compare patients who got one antibiotic versus those who got a combination, to see which group has fewer deaths within 30 days. The goal is to find the best treatment approac…

This study is observing 2,000 children under 2 years old in Ho Chi Minh City who have respiratory infections. Researchers will test for RSV, track how the virus spreads across seasons, and measure the illness's impact on families, including medical costs. No new treatments or vac…

This study tests two ways to help general practitioners (GPs) use antimicrobial stewardship resources when treating respiratory tract infections. One group gets online training and self-audit tools; the other gets face-to-face support. Researchers will track how often GPs use the…

This study looks at the types of germs and their resistance genes in 800 people with pneumonia. Researchers will compare severe and mild cases to understand which microbes and resistance patterns are most common. The goal is to improve how doctors diagnose and treat pneumonia, es…
