Prevalence of hepatitis A virus risk factors in a very low endemic country, Switzerland


Mohler-Kuo, Meichun; Steffen, Robert; Bopp, Matthias; Jacobs, R; Mütsch, Margot (2007). Prevalence of hepatitis A virus risk factors in a very low endemic country, Switzerland. Vaccine, 25(52):8718-8725.

Abstract

We aimed to estimate the population-based lifetime exposure to guidelines-based hepatitis A virus (HAV) risk factors in a country model with very low HAV endemicity. A cross-sectional survey among randomly selected residents of Switzerland aged 20-60 years was performed assessing the HAV exposure risk according to the U.S. and the Swiss guidelines. The adjusted prevalence of lifetime exposure to HAV-associated risk exceeded 80% with travel being the most important risk factor. In addition, not only the HAV vaccination coverage was low but also lack of awareness was widespread. As projections indicate a further increase in travel volume resulting imported HAV infections with subsequent transmission among the resident population are a public health concern and a universal HAV vaccination strategy for HAV should be evaluated.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
