The quality of travel clinics in the Netherlands.

Background: In 1996, the Dutch National Coordination Center for Travelers' Health Advice (LCR) was established to improve uniformity in health advice to travelers and in the quality of national vaccination centers. In this study, we evaluate the influence of LCR guidelines on the quality of travel clinics in the Netherlands.

Methods: In 1997 and 2001, questionnaires regarding implementation of LCR quality criteria were sent to the Dutch travel clinics where most travel advice is given.

Typhoid fever in group travelers: opportunity for studying vaccine efficacy.

Background: Typhoid fever (TF) is a rare disease among travelers to endemic areas, and little is known about its travel-related epidemiology. In addition, efficacy data on TF vaccines in travelers is scanty. During 3 months of 1994/95, six cases of TF were reported in The Netherlands among participants of four package tours to Indonesia provided by the same operator.

The HIV epidemic and its effect on the tuberculosis situation in The Netherlands.

To determine the influence of the HIV (human immunodeficiency virus) epidemic on the tuberculosis situation in the Netherlands, we made a retrospective analysis of all reported tuberculosis cases from 1984 through 1990. We studied the course of the tuberculosis incidence in the Netherlands among the group at highest risk for HIV infection (Dutch males, 25-49 years of age, in Amsterdam). This was compared with the course among same-age Dutch males in areas with lower risk for HIV infection and among other-age Dutch males in Amsterdam.
