Typhoid Detection Technique Improves Diagnostic Sensitivity
The international collaborators have developed a new technique to detect typhoid and estimate its incidence in populations over time. The approach requires only a drop of blood from a finger prick and involves measuring levels of antibodies against two antigens: Hemolysin E (Hlye) and Salmonella lipopolysaccharide (LPS). The researchers simplified the assay so that it can be performed in remote and low-resource regions. The method also employs AI to calculate antibody decay, which provides an indication of when someone was originally infected. This lets the researchers calculate how an infection is spreading throughout a region.
