Coronavirus has hit the European Union institutions.

On Wednesday, two cases of the virus were confirmed by authorities in Brussels, one at the European Defence Agency and another at the Council of the European Union.

According to a statement from the European Defence Agency, a staff member “tested positive and is currently at home in self isolation since symptoms appeared on Saturday evening ... The individual has reported very light symptoms and not returned to the Agency since."

It said the individual had returned to Brussels from a visit to Italy on February 23.

The agency said it had “informed the few staff members who were in close contact with the colleague concerned four days prior to the appearance of symptoms” and told them to "self-isolate themselves for 14 days as a precaution."

Meetings due to be held at the EDA's premises on Rue des Drapiers in Brussels or organized by the agency elsewhere until March 13 have been canceled.

The Council of the European Union said one of its staff members had tested positive for the virus, but pledged not to cancel meetings.

"A colleague from the Information Security Unit of ORG 5 is infected with novel coronavirus COVID-19 following local transmission in Belgium," William Shapcott, the Council's director general for organizational development and services, wrote to Council staff in an email seen by POLITICO.

"The colleague was at work in the GSC [general secretariat] prior to falling ill, so we are taking the necessary measures to limit the risks of transmission of COVID-19 to others," Shapcott wrote, adding, "This means that we are identifying the people with whom the colleague has been in close contact in the workplace since 4 days before the onset of symptoms."

The Council's press office confirmed the case, saying that the virus had been transmitted from another person in Belgium.

A spokesperson said that "due to the nature of his work," the staff member had "limited or almost no direct contact with external delegations or visitors."

The spokesperson added that the Council is not planning to cancel any meetings because of the case.

EU interior ministers are meeting on Wednesday afternoon for an extraordinary discussion on the migration crisis at the Greek-Turkish border.
