           VIRAL IIEPATMS (15 to 180 days)
                TransmMon: Hcpati@ A (HAV)-person to person by ilia fccal-orat route; hepatitis 13 OiBv)-
                    contact with causative agent through blood transfusions, contarrdnated needles, sexual coritac4

                    transrwtted (A-like) or parcntcrally transmitted (B-like).
                Risk Period/Distribution: Year-round, wlui increased incidence from October to December. Occurs
                    countrywide.
                Remarks: Ilc annual num@cr of reported cascs'of acuto viral hepatitis Is about 2,000; most.cases are
                    due to hepatitis A virus (HAV). HAV is widely circulating, but the level may be lower than

                    nonindigenous personnel.

           LZISIIMANIASIS (I week to many me    nths)
                Transmission/Vector Ecology: Bitc of an Infective sand fly. Most sand nies are active between
                    sunsct and dawn, and have a very limited flight range. The primary vector for cutttneous
                    lcishmaniasis (CL) is Plileboromuspapatasii.Dic sand flyvcclor for visceral leislimiiniasls (VL)
                    has not been identified.
                Risk Period/Dlstribijtlon: Transmission of CL and VL is sporadic, but can occur yent-routid,
                    [=king from July flirough September.
                Rcmtirks-. CL is reported rarely; the last reported indigenous case was In 1984 and was cnused by
                    Lcislitnaiiia major. VL, caused by L. dotiovaiii, 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 Sliarikiy,-t and Diiallira, with most cases occurring in
                    children.

            SCIIISTOSOMIASIS (2 lo 6 weeks)
                Transmission/Vector Ecology: Penetration of the skin by wolerbortio larval forms (corcadne) of die
                    parasite, which develop in snails in freshwater habitats. The primary Intermediate liost for
                    Sciiislosoma' maitsoiti (cause of die intestinal form of [tic disease) Is Diottiplialaria arabica, and
                    for S. hacmatobiuitt (cause of the urinary form) is DitILnits wriglitt.
                Risk Period/DiMr-ibution: Transmission occurs year-round, and Increases after heavy mins.
                    Distribution of intestinal schistosomiasis is focal In the southern Dliorar region, In tire vicinity
astern
                    mountainous areas, but has not been associated with any human cases.
                Remarks: Only clinical cases of intestinal sciiistosomiasis have been reported. Fewer than 100 cases
                    have been reported from Araza@ Mtbat, Taqali, and Salainti In the southern Dliotar region.
