The incidence of flavivirus infections has increased dramatically in recent decades in tropical and sub-tropical areas worldwide, affecting hundreds of millions of people each year. Dengue viruses are typically transmitted by mosquitoes and can cause a wide range of symptoms from flu-like fever to organ impairment and death. Although conventional diagnostic tests can provide early diagnosis of acute dengue infections, access to these tests is often limited in developing countries. Consequently, there is an urgent need to develop affordable, simple, rapid, and robust diagnostic tools that can be used at 'Point of Care' settings. Early diagnosis is crucial to improve patient management and reduce the risk of complications. In the present study, a novel laser-cut device made of glass-fiber paper was designed and tested for the detection of the dengue Non Structural 1 (NS1) viral protein and specific IgM in blood and plasma. The device, called PAD, was able to detect around 25 ng/mL of NS1 protein in various sample types in 8 minutes, following a few simple steps. The PAD was also able to detect specific IgM in human plasmas in less than 10 minutes. The PAD appears to have all the potential to assist health workers in early diagnosis of dengue fever or other tropical fevers caused by flaviviruses.
