                   adults. Antibodies to hepatitis B virus (TIBV) occur In a high percentage of the population (30 to

           LrISITMANiASIS (I week to many months)
               TransmissionJVector Ecology: Bile of an Infective sand fly. Most sand flies are active between
                   sunset and dawn, and have a very limited Iliglit rangc.'no primary vector for cutaneous
                   lcislimaniasis (CL) is Plilcbotomuspol)atasii.nic sand fly vector for visceral lelslimaninsis (VL)
                   has not been identified.
               Risk PerioWDistribution- Transmission of CL and VL is sporadic, but can occur y4mt-totitid,
                   Ixaldng from July through September.                   was In 1984 and was caused by
               Remnrks: CL is reported rarely; the last reported indigenous casc
                   Leisitinattia major. VL, caused by L. dotiovatti, is reported sporadically, and there usually are
                   fewer than 10 cases a year (a total of 127 cases from 1978 to 1985). VL has been reported In the
                   noriticastern inland mountain villages of Sitarikiya and Dlialifra, wi(ii most cases occurring In
                   children.

           SCIIISTOSOMIASIS (2 to 6 weeks)
               TrnnsmMori/Vector @ology: Penetration of the skin by walciborne larval forms (cctcarinc) of the
                   parasite, which develop in snails in freshwater liabilits.'nic primary Intermediate host for
                   scilistosom6 malzsoizi (cause of the Intestinal form of the disease) Is Dioinplialaria arabica, and
                   for S. hacniatobium (cause of the urinary form) is Dii[imtis RTighti.
               PJsk Period/Dlstribution: Transmission occurs year-round, and Increases after heavy mins.
                   Distribution of intestinal schistosomiasis is focal In the southern Ditolar region, In the vicinity
                   of Saialah (in the coastal wadis).nic snail intermediate host has been detected In flio northeastern
ainous areas, but has not been associated with any human cases.
               Remor@: Only clinical ea= of intestinal schistosomiasis have been reported. Fewer than 100 cases
                   have been reported from Araza@ Mrbut, Taqnli, and Sololaii In the southern Dliorar region.
