Emerg Infect Dis. 2022 Nov;28(11):2316-2320. doi: 10.3201/eid2811.220239.


We applied a new serosurveillance tool to estimate typhoidal Salmonella burden using samples collected during 2020 from a population in Juba, South Sudan. By using dried blood spot testing, we found an enteric fever seroincidence rate of 30/100 person-years and cumulative incidence of 74% over a 4-year period.
