                     countrywide.

                     due to hepatitis A virus (ILAV). I-LAV is widely circulating, but the level may be lower than

                     Antibodies occur in an estimated 90 imrccnt of children by age 10, and in almost IW percent of
                     adults. Antibodies to hepatitis B virus (TIBV) occur In a high percentage of the population (30 to
                     40 percent). The tlBV carrier rate Is estimated at nearly 3 percent, resulting in a high number of
                     chronic cornplicauons. 'Die delta agent 0 IDV) has not been reported, but is suspected. ParenternUy-

           LEISIIMANIASIS (I week to many months)
                 Transmission/Vector Ecology: Bite of nn infective sand fly. Most sand flies are active between
                     sunset and dawn, and have a very limited flight range. The primary vector for cutaneous
                     Icishmaniasis (CL) is Plitebotomuspopotasii. The sand fly vector for visceral lelslimaniasis (VL)
                     has not been identified.
                 Risk Period/Distribtition: Transmission of CL and VL is sporadic, but can occur year-round,
                     ranking from July through September.
                 Rcmttrks: CL is reported rarely; the last reported indigcnoui case was In 1984 and was cnused by
                     Lcislitnaiiia major. VL, caused by L. doiiovaiii, is reported sporadically, and there ilsually are
                     fewer than 10 cases a year (a total of 127 cases from 1978 to 1985). VL has been reported In the
                     northeastern inland mountain villages of Sliarikiya and Dltaliirs, with most cases occurring In
                     children.

            SCIIISTOSOMLASIS (2 to 6 weeks)
                 TrunsmMon]Vcctor Ecology: Penetration of i     lie skin by wnterborne larval forms (corcadae) of the
                     parasite, which develop in snails in freshwater habitats. The primary Intermediate host for
                     ScllistosolII6 mallsolli (cause of Uic intestinal form of the disease) Is Dioniplialaria arabica, and
                     for S. haemarobiurit (cause of the urinary form) is Bitlimiis wriglift.
                 Risk Perlod/Disitibution: Tmnsrrdssion occurs year-round, and Increases after heavy mins.
                     Distribution of intestinal sciiistosomiasis is focal in the southern Dliotor region, In ific vicinity
te host has been detected In die northeastern
                     mountainous areas, but has not been associated with any human cases.
                 Remarks: Only clinical cases of intestinal sciiislosomiasis have been reported. Fewer than 100 cases
                     have been reported rrom Araza4 Mrbnt, Taqati, and Sainialt In the southern Dliofat region.
