Sister chromatid exchange (SCE) was measured in peripheral lymphocytes of 90 workers from 14 hospital pathology departments in Israel who were occupationally exposed to formaldehyde (FA) and of 52 unexposed workers from the administrative section of the same hospitals. The mean exposure period to FA was 15.4 years (range 1-39). The results of SCEs are(More)
The appearance of "new" infectious diseases, the reemergence of "old" infectious diseases, and the deliberate introduction of infectious diseases through bioterrorism has highlighted the need for improved and innovative infectious disease surveillance systems. Traditional current surveillance systems are generally based on the recognition of a clear(More)
We studied the 2-year death rate of 246 adults discharged from hospital after experiencing acute West Nile Virus infection in Israel during 2000. The age- and sex-adjusted death rates were significantly higher than in the general population. This excess was greater for men. Significant adverse prognostic factors were age, male sex, diabetes mellitus, and(More)
Located along the migratory route of birds traveling between Africa and Europe, Israel is endemic for West Nile fever (WNF). Since the first recognized outbreak in 1951 [1, 2], further WNF outbreaks have been reported in Israel in 1952, 1953, 1957 and 1980, and from July to September 2000 a large outbreak of WNF swept through central and northern Israel,(More)
BACKGROUND In a previous study, we found a relatively low compliance with influenza vaccination among the elderly (65 years and over) in both 1998/1999 and 1999/2000 winters. Prior to the 2000/2001 winter season, a campaign was conducted by the Israeli Ministry of Health and the local health maintanance organizations for improving compliance with influenza(More)
BACKGROUND Because they are rarely associated with actual infections, Bacillus species are usually defined as contaminants. However, when isolated, they require precise laboratory identification and may influence treatment. METHODS Our aims were to examine the seasonality of Bacillus spp isolates cultured from clinical blood specimens. Blood culture(More)
BACKGROUND Although influenza is usually a mild self-limiting disease it can cause serious complications in high risk groups. The economic costs of influenza are large due to the burden on the health system and absenteeism from work. There is evidence that the vaccine is underused in groups targeted for vaccination. OBJECTIVES To estimate: a) the(More)
In this paper we report the use of the open source Spatiotemporal Epidemiological Modeler (STEM, to compare three basic models for seasonal influenza transmission. The models are designed to test for possible differences between the seasonal transmission of influenza A and B. Model 1 assumes that the seasonality and magnitude of(More)
RATIONALE Although cancer is a main cause of human morbidity worldwide, relatively small numbers of new cancer cases are recorded annually in single urban areas. This makes the association between cancer morbidity and environmental risk factors, such as ambient air pollution, difficult to detect using traditional methods of analysis based on age(More)
West Nile Virus (WNV) is endemic in Israel, affecting yearly 40-160 individuals. Israel is located on a central migratory path between Africa and Eurasia and most West Nile Fever (WNF) cases reported in recent years were among residents of the coastal plain. The aim of the study was to evaluate the seroprevalence of WNV among the Israeli population and to(More)
