Schistosomiasis japonica differs significantly from Schistosoma mansoni infection in several epidemiologic, immunologic, and operational characteristics for control. Because of numerous nonhuman hosts, transmission remains high despite aggressive case finding and treatment of human cases. Diagnosis of infection using the Kato-Katz stool technique is less sensitive and specific in this than in other species of human schistosomes, making case finding and treatment a less effective approach to control.

The prevalence, incidence, and intensity of infection and schistosome-induced hepatomegaly significantly decreased within 3-4 years of treatment and then stabilized despite continual population-based chemotherapy. Hepatomegaly rapidly developed in acutely infected persons, with 82% of subjects developing hepatic enlargement within 2 years of reinfection.

Three isolates with vancomycin MICs ranging from 8 to 256 micrograms/ml all hybridized with a vanB probe. Restriction endonuclease analysis of chromosomal and plasmid DNA suggested that all isolates tested were derived from a single clone.

This rise has occurred at a faster rate than that for the United States overall. Although the HIV epidemic is largely to blame for the resurgence of tuberculosis nationwide, its impact on tuberculosis locally has been muted.

Results: Twenty-six patients with malaria were identified. Fifteen patients were immigrants who had acquired malaria while visiting their country of origin, particularly West Africa.
Travelers to developing countries are at risk of contracting tropical infectious diseases that they or their physicians may be unfamiliar with. Proper pre-travel counsel should be given concerning general health risks that may be encountered abroad, immunizations, malaria prophylaxis and prevention and treatment of traveler's diarrhea. In Rhode Island, expert advice may be obtained at the Traveler's Clinics at the Miriam Hospital in Providence (401-274-3700 or 331-8500, ext.
