                       ACUTE SCHISTOSOMIASIS (KATAYA.MA FEVER)

         I. Communicability
              A. Route-man to man spread not seen. Disease acquired by
                contact with infected fresh water by swimming, wading,
                washing, etc.
              B. isolation of patients - not required.
              C. Contact Prophylaxis - not required.

         II.  Incubation Period
                  Schistosomiasis derinatitis (swimmer's itch) occurs within
              24 hours of penetration of skin by the infective forked
              tailed cercariae.   Rarely occurs on primary exposure, so
              probably a sensitization phenomenon. Clinical syndrome
              occurs 1-3 months later and starts with an "enteric
              fever" like picture which resembles typhoid fever or
              brucellosis.

         III. Diagnosis
                  Exposure east of the great sand belts S.haematobium
                which is not associated with an acute syndrome.
                  Exposure west of the great sand bolts S. mansoni which
                could present as Katayama fever.


         Symptoms - Fever (all)           Signs                 Lab
         chills                         adenopathy           eosinophilia up
         sweating                       hepatomegaly-50%      to 40% in all
         headache                       splenomegaly-10%        patients
         cough-most
         diarrhea-50%

                Micro:
                   Stool exam shows eggs in most patients with acute
                schistosomiasis, however, stools may be negative since
                present in stool only 40-55 days following infection with
                S. mansoni.

                Serolocjy:
                  not useful in acute cases.

                Radiology:
                  not useful acutely
                Exposure history is essential to consider the diagnosis.
                  Absence of eosinophilia (>BOO cell/mm) excludes the
gnosis.

         IV. Duration
                  Treated - aborts chronic sequelae but may not limit acute
                            disease.
                  Untreated - 2-4 weeks for resolution of acute symptoms.
