European Commission Vice President for promoting the European Way of Life Margaritis Schinas tested positive for COVID-19 and is self-isolating.
"I have just learned that my regular scheduled COVID19 test ... came back positive. I am now self-isolating as required," Schinas said on Twitter.
The Belgian capital, the headquarters city of the main EU institutions, has one of the highest COVID-19 infection rates in the world, as a second wave of the virus breaks over Europe.
An EU summit was disrupted this month when three leaders had to stay away to self-isolate after coming into contact with a carrier, and two foreign ministers and a prime minister have tested positive.
