Moroccan variant of the measles virus found in Brussels sewage water
A Moroccan variant of the measles virus, genotype B3, has been detected in high concentrations in Brussels sewage, researchers from KU Leuven reported. The virus, linked to an ongoing outbreak in Morocco, has been on the rise across Europe, with cases already reported in the Netherlands, Spain, and France.
