In a retrospective study (1984-1992), new cases of human echinococcosis were registered in Switzerland based on information obtained from (a) questionnaires sent to 294 of the 300 acute hospitals in all parts of the country and to 17 institutes of pathology (268 answers form hospitals: 91%), and (b) from tracing back cases reported under the official notification system since 1 January 1988 by laboratories to the Federal Health Office or recorded at the Institute of Parasitology in Zurich. Cases were regarded as verified if the diagnosis was documented by unequivocal findings (by radiology, ultrasonography, pathomorphology etc. and often by additional detection of anti-Echinococcus antibodies). Patients with antibodies but without reports on further findings were classified as suspected cases. ⋯ Based on a total population (Swiss nationals and foreigners) of 6.62 million in 1988 and the case numbers of 1984-1992, the following average annual incidence rates per 100,000 inhabitants were calculated: 0.51 for all new cases, 0.38 for CE, 0.11 for AE and 0.01 for NSE. In the 37 years since 1956 there has been steady increase in new cases of CE due to the importation of such cases by foreigners, whereas the case numbers of AE have remained nearly constant with a range between 7 and 10 new cases per year. In our study 258 suspected seropositive patients were registered but not added to the total number of cases, due to the lack of further findings.

The health care market is a very particular one that is mainly characterized by the absence of information and transparency at every level, particularly between the physician-supplier and the patient-consumer. On this market it is up to the physician to evaluate and define the patient's needs and to decide which are the most effective goods for the patient. ⋯ Professional uncertainty inherent in the practice of a stochastic art such as medicine will "always" give an ethical justification for supplier-induced demand or for the pursuit of "maximal" and/or "defensive" care when market competition is perceived by the physician as a threat to his/her income or employment. Time is ripe for consumers and physicians empowerment in the aim to promote better self-management of health and more thoughtful access to care (for consumers) and more evidences based medicine for physicians.
