West Nile fever (WNF) is endemic in Israel. In 1999, country-wide adult mosquito surveys were initiated and intensified after the 2000 country-wide outbreak of WNF in humans. In 8 consecutive yr, groups of male and female specimens of different species and from different locations were tested for infection with West Nile virus (WNV). Three species made up >87% of the total catch: Culex pipiens L. (52%), with an infection rate (IR) of 0.5; Cx. perexiguus Theobald (20%), with an IR of 2.7; and Aedes caspius Pallas (15%), with an IR of 0.6. The geographical and temporal distribution of WNV-infected mosquitoes was similar but was not parallel to the seasonal abundance of the populations. The seasonal occurrence of human cases is in correlation with the finding of WNV-positive mosquito specimens reaching a peak 1 mo later than the mosquito peak. The relative importance of the mosquito species in the epidemiology of WNF is discussed. Cx. perexiguus is considered the major vector of WNF in Israel.

Objective-Speed at the time of a bicycle crash is an important determinant of the amount of energy transmitted. Controlling for speed is thus important in the evaluation of outcomes and effectiveness of intervention strategies. This study was conducted to evaluate the accuracy of self reported speed in a population of recreational cyclists. Methods-Children's and adults' bicycle speeds were measured with a radar gun as they rode along a closed road at weekend recreational events. Cyclists were then stopped and asked to estimate their speed. Measured speed, cyclist's estimate oftheir speed, age, and sex were documented. Parents were also asked to estimate their child's speed. Results-One hundred and fifty two cyclists from 4 to 80 years of age participated. Seventy per cent were children 13 years of age or younger. The mean (SD) speed of this group was 8.9 (2.5) mph. Cyclists age 14 and older were traveling at a mean speed of9.7 (2.87) mph. Estimated speeds were significantly higher than measured speeds for this older group, but there was no significant difference between mean measured and estimated speeds for the younger riders. There was also no significant difference between measured and estimated speed for males and females. Parents estimated their child's speed quite accurately. Conclusions-Self reported speeds for children were in close agreement with measured speeds and, thus, are sufficiently accurate to be a useful measure of crash severity in evaluating heimet effectiveness.

This study examined the prevalence, willingness to report, and treatment preferences for suicidal ideation among state prison inmates. The Beck Scale for Suicide Ideation (BSS) and a novel questionnaire were completed by 67 inmate-patients. The BSS score was in the high range for 15% of general population (GP) and 40% of Intermediate Care Program (ICP) patients, with 19% of ICP inmates reporting a "moderate to strong" desire to commit suicide. A majority (64% GP, 86% ICP) had prior suicide attempt(s). Forty-two percent of GP and 31% of ICP inmate-patients were unlikely to tell mental health staff about suicidal thoughts. Family contact and talking with mental health staff were preferred interventions. ICP inmates preferred staff visits and observation in their own cells, but GP inmates did not. Only a small minority (14% GP, 21% ICP) favored transfer to a crisis observation cell, but the least desired option was talking to a corrections officer. While many inmate-patients reported experiencing suicidal thoughts, they preferred not to inform staff. Almost 80% did not favor the current primary intervention: the observation cell. Alternative or supplementary options should be considered.
