Background: Brucellosis is an endemic infection affecting the Mediterranean Basin, Arabian Peninsula, India, Mexico, and South America. Data on brucellosis infections in children are limited.

Objectives: To review and characterize the clinical presentation of pediatric patients diagnosed with brucellosis in a tertiary medical center.

Methods: Retrospective data analysis was conducted on all pediatric patients from January 2010 to December 2020 admitted to the pediatric department with a diagnosis of brucellosis based on a positive serology test or growth of Brucella bacteria in blood culture.

Results: The study comprised 53 children aged 0–18 years. The mean age at presentation was 11.01 ± 4.91 years; 39 male (73.6%). Pre-infection exposure to unpasteurized milk or unvaccinated livestock was reported in 37 (69.8%). Fever was present in 64.6%, followed by arthralgia (49%), loss of appetite (42.3%), and weight loss (24.6%). Gastrointestinal symptoms were reported in 52.8% and included abdominal pain (34.6%), nausea (28.3%), vomiting (24.5%), and diarrhea (2.6%). Eight patients experienced pancytopenia (15.1%). The median length of intravenous antibiotic treatment was 7 days (range 3–14 days) and for oral antibiotic treatment 6 weeks (range 2–24 weeks). Most patients were initially treated with intravenous gentamycin (90.5%) and long-term oral antibiotics, most commonly doxycycline. Two (3.7%) required admission to the pediatric intensive care unit. No mortality was documented, and all cases of relapses were successfully treated.

Conclusions: Pediatric brucellosis is an acute febrile disease often associated with rheumatologic complaints. Patients 8–18 years of age also presented with headache, weight loss, and night sweats.

Background: The epidemiology of human brucellosis (HB) continues to evolve.

Objectives: To describe the current epidemiology of HB in Israel in general and in the population at risk.

Methods: We calculated the incidence of HB in Israel for the period 2009–2015, overall and for the Arab population. Data are based on mandatory reporting of HB in Israel, defined clinically with either laboratory confirmation or epidemiological linkage to a laboratory-confirmed case. We mapped the geographic distribution of HB throughout the study period according to localities. We specified localities with high incidence (≥ 10 per 100,000 population) and mapped the distribution of dense localities with time.

Results: The incidence of HB in the general population in Israel increased sharply from 1.9 per 100,000 in 2009 to a peak of 7.3 per 100,000 in 2014. Each year, 95–100% of cases occurred among Arabs, thus the incidence in the Arab population increased from 10 per 100,000 in 2009 to 33.5 per 100,000 in 2014. Throughout this period 133 different localities reported at least one case of HB, and of these 20 were high-incidence localities during one year at least. During the period 2009–2013 the number of affected localities ranged from 35 to 44 per year and the disease was local, while in 2014 there were 82 localities distributed across the country.

Conclusions: We demonstrate the importance of analyzing incidence in the population at risk for a disease. HB is an urgent public health issue in the Arab population in Israel, mandating an immediate and long-term eradication and control program.

Background: Human brucellosis is common in southern Israel among the semi-nomadic Bedouin, a population that consumes unpasteurized dairy products. Though camel milk ingestion is a known mechanism for brucellosis acquisition, only a few reports of sporadic cases have been published in the medical literature.

Objectives: To describe a local brucellosis outbreak in 15 extended Bedouin family members, following ingestion of infected camel milk.

Methods: Data regarding patient’s clinical manifestations, laboratory findings, treatment and outcome were collected from the hospital and the health fund clinics’ computerized database. Camel’s blood and milk were tested for Brucella serology and culture. Cases were defined by positive Rose Bengal test, symptoms correlating with brucellosis, and consumption of infected camel milk.

Results: Fifteen patients were diagnosed with acute brucellosis from March to June 2011. Sixty percent of cases had serum agglutination test titers of 1:160 or higher and 4/8 (50%) had positive blood culture for Brucella melitensis. Arthralgia and fever were the most consistent clinical manifestations. Blood and milk serology and milk culture taken from the female camel were positive for Brucella melitensis.

Conclusions: The treating physicians must consider the possibility of infected camel milk ingestion as the mode of infection, both in sporadic cases and in outbreaks of brucellosis.

Background: The majority of human brucellosis cases in Israel are caused by the ingestion of unpasteurized dairy foods produced from unlicensed family-owned flocks whose products are sold door-to-door at low prices. Exposure to infected farm animals is another major cause of infection.

Objectives: To determine, by examining recent incidence data and brucellosis control programs, whether a reduction in the incidence of human brucellosis in Israel can be sustained.

Methods: Case information is reported to the Health Ministry and national data are compiled and analyzed by the Division of Epidemiology. The current study focuses on data from 1998 through 2009 and discusses several of the major prevention and health education programs that have been implemented.

Results: An incidence decline of almost 70% during the period 1998–2002 was followed by a return to previously existing levels, although the incidence has remained consistently lower than in past decades. The disease is mostly limited to certain sectors of the rural Arab population. In 2009 the incidence rate per 100,000 population was 7.0 among Arabs compared with 0.2 among Jews. Between 1998 and 2009, 63% of cases were from the Beer Sheva and Acre health districts, which together comprise 15.5% of the Israeli population. Control programs - including efforts to combat brucellosis in animals and to discourage the sale of unpasteurized homemade dairy products - have met with partial success.

Conclusions: Without routine vaccination of all family-owned flocks, more effective restraints on the market for unpasteurized dairy foods and improved regional cooperation, human brucellosis will continue to be a contained, but persistent, health problem in Israel due to cultural behavior, socioeconomic factors, and the regional political environment.
