Prime minister Xavier Bettel was admitted to hospital on Sunday for follow-up tests and analysis of his covid-19 infection. Bettel had been in isolation since 27 June when he tested positive for coronavirus--he had self-tested and self-isolated before getting a medical test that confirmed the positive result.
He had shown some mild symptoms of the infection, including a fever and headaches, but was initially said to be carrying out his normal duties from his isolation.
Bettel was waiting for his second shot of the AstraZeneca vaccine, having received his first dose on 6 May.
