Hepatitis E virus (HEV) is an emerging cause of viral hepatitis worldwide. Recently, HEV-7 has been shown to infect camels and humans. We studied HEV seroprevalence in dromedary camels and among Bedouins, Arabs (Muslims, none-Bedouins) and Jews and assessed factors associated with anti-HEV seropositivity. Serum samples from dromedary camels (n = 86) were used to determine camel anti-HEV IgG and HEV RNA positivity. Human samples collected between 2009 and 2016 from >20 years old Bedouins (n = 305), non-Bedouin Arabs (n = 320) and Jews (n = 195), were randomly selected using an age-stratified sampling design. Human HEV IgG levels were determined using Wantai IgG ELISA assay. Of the samples obtained from camels, 68.6% were anti-HEV positive. Among the human populations, Bedouins and non-Bedouin Arabs had a significantly higher prevalence of HEV antibodies (21.6% and 15.0%, respectively) compared with the Jewish population (3.1%). Seropositivity increased significantly with age in all human populations, reaching 47.6% and 34.8% among ⩾40 years old, in Bedouins and non-Bedouin Arabs, respectively. The high seropositivity in camels and in ⩾40 years old Bedouins and non-Bedouin Arabs suggests that HEV is endemic in Israel. The low HEV seroprevalence in Jews could be attributed to higher socio-economic status.

This paper surveys the private lands owned by of Sultan Abdülhamid II in Palestine and analyzes their spatial distribution and impact, in the context of regional imperial policy. In the last quarter of the nineteenth century, the Ottoman Empire faced serious external and internal problems. Sultan Abdülhamid II (r. 1876-1909) used various traditional and modern methods in order to increase the internal cohesion of the empire and strengthen it vis-à-vis external threats.

One unique measure taken by the sultan was the purchase of large tracts of land. He became one of the largest landowners in the empire. In Palestine alone, the sultan purchased around 3% of the total area and initiated measures to increase these lands' productivity for his Privy Purse. In addition to gaining economic profit, Abdülhamid II employed his private lands to solve problems which challenged the sovereignty of the empire. These included attempts to settle the Bedouins, the establishment of new towns in order to subjugate nomads in regions where they threatened rural settlements, settling Muslim refugees from the Caucasus and the Balkans, and protecting strategically sensitive lands located on the frontiers, by purchasing them and thus keeping them out of the hands of others.

Toxoplasmosis seroprevalence varies considerably between countries. We studied the seoprevalence of Toxoplasma gondii IgG antibodies in a national sample of the Israeli population; 2794 sera were tested. The highest age-adjusted seroprevalence rate was in Arabs (non-Bedouins) (60·4%), significantly higher compared to the rate in Jews (19·9%) and Bedouins (27·5%) (P < 0·01). There were no significant gender differences. Seropositivity increased with age in all population groups. For Jews, seropositivity was associated with place of birth and socioeconomic status. A finding of low seroprevalence rate in Bedouins despite their poor living conditions and close contact with livestock is surprising, and might be attributed to the dry and hot climate conditions in their area of residence. In women of reproductive age the seroprevalence was 15·1% in Jews, 25·4% in Bedouins and 72·3% in Arabs (non-Bedouins). Thus, the majority of pregnant women are susceptible to primary infection with T. gondii, and the risk for congenital toxoplasmosis remains high.

In the summer of 2000, a team of medical and affiliated workers visited the South Sinai Desert to assess the medical problems and needs of the Bedouin population. This paper reports on the ENT diseases of this population, and discusses their healthcare needs.
