Paper devices better detect malaria in Ghana

New paper-based devices have proven more effective than existing methods at detecting malaria in asymptomatic individuals in Ghana, potentially aiding in disease elimination efforts. The devices, using cheap paper strips, detected significantly more malaria infections in a study of 266 volunteers compared to microscopy and rapid diagnostic tests, with a 96.5% sensitivity rate. The devices use mass spectrometry to identify malaria-specific antigens. This advancement could improve malaria surveillance, especially in areas where vaccination is increasing. The technology is also being adapted to detect other diseases, and the researchers are in talks with the Ghanaian government about implementation.
