Antarctica had been free of COVID-19 until now. The continent has no permanent residents, but about 1,000 people, including scientists and other workers, stayed there this past winter, The Guardian reported.

Just a few days before the Antarctic outbreak emerged, three cases of COVID-19 were reported on a Chilean navy ship that had brought supplies to the research base, according to the BBC.
