Wearable NIRS device for malaria detection
Calixte de Belloy · Scholarly review . · 2025
Malaria remains a serious health problem globally, causing millions of cases and many deaths each year. For example, in 2023, malaria spread to 263 million people and killed 597,000 of them globally. Detecting the disease early is very important because it helps doctors decide on the right treatment to save lives and stop the further spread of the illness. However, most current tests require a blood sample, which can be painful, expensive, and difficult in remote areas. Here I suggest a new, non-invasive method that uses a wearable near infrared spectroscopy (NIRS) device which uses near-infrared light to check for signs of malaria in the blood. The device continuously monitors blood properties and uses simple computer programs to look for patterns that indicate malarial infection. It sends the data wirelessly in real time to a phone or computer, which makes it possible to start treatment quickly and reduce the risk of serious illness. This easier and less expensive approach could work well in places with few medical facilities, helping to catch malaria early and treat it faster, which may lead to fewer severe cases and lower death rates.
