I was thinking about the Swiss Tropical and Public Health Institute and assumed most western countries have something like that. The German Wikipedia article about "Tropeninstitut" mentions the KIT for the Netherlands [0] altough that article sounds way less about medicine than the Swiss one or the German Bernhard Nocht Institute for Tropical Medicine or the Belgian one you mentioned.
