Prime Minister Jean Castex, who has been fully vaccinated, tested positive for the virus after returning to France from a visit with ministers in Brussels, his office confirmed to CNN.
On his return from Belgium, Castex learned that his 11-year-old daughter had tested positive for the coronavirus, according to CNN affiliate BFMTV. The prime minister then also tested positive and is self-isolating.
His Belgian counterpart, Prime Minister Alexander de Croo, is now in self-isolation along with four other ministers after their meeting, according to the Belgian public broadcaster RTBF.
Castex has no symptoms and was feeling fine when the positive test came back Monday night, BFMTV reported.
Despite being a “contact case” – a person who had contact with someone else with the coronavirus several times before – and his wife contracted the disease, Castex had never contracted the disease herself until now.
