Typhoid Sero Surveillance Study
A population-based initiative that uses serological testing to detect antibodies such as HlyE, LPS, or Vi, in blood samples, including dried blood spots, to estimate both current and past Salmonella Typhi infections. By identifying subclinical or previously undiagnosed cases often missed by traditional blood culture methods, the study provides more accurate estimates of typhoid seroincidence and seroprevalence in communities.
