The EU chief was in Lisbon last week, for meetings with top Portuguese officials during which she came into contact with a person who tested positive for Covid-19.

Ursula von der Leyen tweeted, on 5 October, “I’ve been informed that I participated in a meeting last Tuesday attended by a person who yesterday tested positive for COVID-19. In accordance with regulations in force, I’m therefore self-isolating until tomorrow morning. I’ve tested negative on Thursday & am tested again today”.

According to euronews, she is not experiencing any virus symptoms for the moment, but she will not be able to attend the European Parliament plenary.
