Why are there several health networks in Belgium?

In Belgium there are four health networks;

  • the Brussels Health Network,
  • the Walloon Health Network
  • two local networks in Flanders:
    • Cozo (region of Ghent and Antwerp)
    • VZN (Leuven region).

They all communicate with each other through the federal eHealth portal project (Project Hub Métahub). The reason for these multiple health networks is historic.
