Seroprevalence of Scrub Typhus, Typhus, and Spotted Fever Among Rural and Urban Populations of Northern Vietnam

AbstractRickettsial infections are recognized as important causes of fever throughout southeast Asia. Herein, we determined the seroprevalence to rickettsioses within rural and urban populations of northern Vietnam. Prevalence of individuals with evidence of prior rickettsial infections (IgG positive) was surprisingly low, with 9.14% (83/908) testing positive to the three major rickettsial sero...

Clinical and Epidemiological Characteristics of Japanese Spotted Fever and Scrub Typhus in Central Japan, 2004–2015

Fever and Scrub Typhus Rickettsiae

The rickettsiae have always been difficult to study because convenient titration and isolation techniques have not been available for the study of these organisms. In recent reports (3, 5), however, we demonstrated the use of a sensitive plaque test for measuring concentrations of typhus and spotted fever rickettsiae. Studies were then initiated to determine whether this assay system is appropr...
