NATO has confirmed that a member of its staff at its Brussels headquarters has tested positive for coronavirus.
The employee had returned from a holiday in northern Italy when they began to feel unwell at the end of last week, a statement said.
The staff member is currently at home in self-isolation, while other colleagues are also self-isolating.
A NATO spokesperson said: "All NATO headquarters staff have also been informed of the confirmed case.
"NATO continues to monitor the situation on an ongoing basis and to take all necessary measures."
NATO previously announced there were three confirmed cases of COVID-19 within its "wider SHAPE [Supreme Headquarters Allied Powers Europe] community".
However, it said the affected individuals had not entered the SHAPE headquarters in Mons, west Belgium, after returning home from "foreign travel".
Meanwhile, in the UK, Aldershot Garrison Sports Centre in Hampshire has closed after a visitor tested positive for Coronavirus.
The UK has 280 confirmed cases of COVID-19 and three people have died in UK hospitals.
