Outbreaks of cercarialdermatitis which occurred in recreational lakes in the Netherlands were studied and a method for direct rapid detection of the parasite Trichobilharzia in water samples was developed. A standardized questionnaire with questions on health complaints and exposure was distributed to individuals who developed symptoms of cercarialdermatitis after visiting fresh water lakes. Snails from the suspected lakes were examined for the presence of Trichobilharzia by microscopy and PCR. Water samples were concentrated by filtration and examined by PCR. Water quality was tested according to European Bathing Water Directive 76/160/EEG. Trichobilharzia was detected in snails and water samples from lakes which met European bathing water standards. Despite a response of 25.5%, epidemiological data suggested that longer and more frequent exposure to the water resulted in increased reporting of symptoms of cercarialdermatitis and confirmed the importance of exposure as a risk factor. A novel method for direct detection of Trichobilharzia, which includes concentration of water samples by filtration and detection of the parasite by PCR proved to be a valuable and simple tool for confirmation of presumptive outbreaks, particularly when snails could not be found in the suspected water and public health protecting measures were necessary.

The Impact

An assessment of the impact of the new microbial water quality standards of the proposed EU Bathing Water Directive on the classification of designated Irish coastal bathing areas is presented. The new standards are applied retrospectively to the microbial water quality results for the bathing seasons of 1999, 2000 and 2001, and the outcome is compared with that recorded under the present Bathing Water Directive. A Microsoft EXCEL application was developed to generate the retrospective bathing area classifications according to the proposed Directive (Excellent, Good, Poor). It was found that the number of Irish coastal bathing areas not attaining ‘Excellent’ classification (as would be required at present for the Blue Flag award) was trebled; the number attaining ‘Good’ classification was increased by about 50%, and the number attracting ‘Poor’ classification (equivalent to ‘Fail’ under the present Directive) was increased nine-fold. Some of the shortcomings of the proposed Directive and suggestions for its revision are discussed.

There is a growing belief that IT can improve public management in general. The Dutch policy and services with regard to the elderly are no exception. Obviously, IT opportunities in the healthcare domain play a central role in this, since the main objective of policies is to sustain the independent functioning of the elderly in everyday social life. In this research four IT opportunities for elderly policy in The Netherlands are explored through discussion meetings with elderly, and consultation of experts in the field of elderly policy and services. The IT opportunities are designed to align the different levels of motivation and skills of elderly to use IT. Four IT pilot projects are defined, which take into account the costs and benefits of these opportunities to improve the elderly policy chain in The Netherlands.

ABSTRACT The water in the canals and some recreational lakes in Amsterdam is microbiologically contaminated through the discharge of raw sewage from houseboats, sewage effluent, and dog and bird feces. Exposure to these waters may have negative health effects. During two successive 1-year study periods, the water quality in two canals (2003 to 2004) and five recreational lakes (2004 to 2005) in Amsterdam was tested with regard to the presence of fecal indicators and waterborne pathogens. According to Bathing Water Directive 2006/7/EC, based on Escherichia coli and intestinal enterococcus counts, water quality in the canals was poor but was classified as excellent in the recreational lakes. Campylobacter, Salmonella, Cryptosporidium, and Giardia were detected in the canals, as was rotavirus, norovirus, and enterovirus RNA. Low numbers of Cryptosporidium oocysts and Giardia cysts were detected in the recreational lakes, despite compliance with European bathing water legislation. The estimated risk of infection with Cryptosporidium and Giardia per exposure event ranged from 0.0002 to 0.007% and 0.04 to 0.2%, respectively, for occupational divers professionally exposed to canal water. The estimated risk of infection at exposure to incidental peak concentrations of Cryptosporidium and Giardia may be up to 0.01% and 1%, respectively, for people who accidentally swallow larger volumes of the canal water than the divers. Low levels of viable waterborne pathogens, such as Cryptosporidium and Giardia, pose a possible health risk from occupational, accidental, and recreational exposure to surface waters in Amsterdam.

It is commonly argued that the decision to introduce a new vaccine is properly based on objective and measurable criteria, including disease burden and efficacy of the vaccine. Moreover, new vaccines are to be introduced rapidly and globally: delay is difficult to justify. Historical studies of new vaccine introductions paint a rather different and more complex picture. The few studies comparing new vaccine introduction in different countries suggest that ‘evidence’ for the efficacy of a vaccine was commonly subjected to varying interpretations. This paper, based on analysis of the introduction of the measles–mumps–rubella (MMR) vaccine in Denmark and the Netherlands, takes this argument further. Though both countries are – and were – small welfare states with well-organised national immunisation programmes, both adopted MMR a full decade after its introduction in the USA. The paper suggests that the reasons for delaying, in each case, are a reasonable reflection of each country’s concerns, perceptions of the three diseases, and technological approaches already adopted. There were differences in each of these respects. The decision to adopt MMR, which each country eventually took, was significantly influenced by the political and ideological changes taking place in the 1980s, including a growing emphasis on costs and benefits, as well as the growing influence of the international context.

One of the major problems in trying to design wastewater treatment schemes to protect bathing water for coastal communities with combined sewerage systems, is to ensure that discharges of storm water do not prejudice compliance with the requirements of the EC Bathing Water Directive. In order to develop an appropriate storm water management strategy for the Fylde coast it was necessary to integrate a number of mathematical models simulating the hydraulic behaviour of the sewerage system and the dispersion of discharges in the receiving waters. From the sewerage system modelling it was apparent that frequent discharges of storm water to the bathing waters could only be avoided by the provision of considerable additional storage in the system. By means of a suitably calibrated simplified sewer model it was possible to investigate the volumes of storm water generated by a 15 year record of local rainfall when different amounts of extra storage and different pumping regimes were employed. The results from these investigations were used to determine the probable concentrations of faecal bacteria in the coastal waters for each of the 15 bathing seasons and determine the percentage of time for which faecal coliform concentrations exceeded the Bathing Water directive standards for the model grid cells representing the identified bathing waters. As a result of the extensive integrated modelling programme for the Fylde coast it has been possible to design a base flow and storm water management system which should maximize the flow passed forward for treatment whilst also ensuring that there is just sufficient storage to ensure protection of the towns from flooding and the compliance of the beaches with the Bathing Water Directive standards.
