The Chilean health ministry said that 2,660 new cases of novel coronavirus were recorded by authorities inside the country on Wednesday — the highest number in a single day since the pandemic began.

A total of 34,381 people have been infected by the virus in Chile, 346 of whom have died, according to the ministry.

Chilean health minister Jaime Mañalich said that the spike prompted authorities to place the capital of Santiago and some of its surrounding areas under a seven-day mandatory quarantine, which President Sebastian Piñera said will start Friday.

Additionally, all press staff assigned to the Presidential palace of La Moneda will be completing a preventive 14-day stay-at-home order, after a member of the media tested positive for coronavirus, Piñera’s office said on Wednesday.
