New Antarctica Teams Take Extra Measures to Keep Coronavirus Out

（单词翻译）

America's first flight to Antarctica after the southern winter arrived with crews taking extra safety measures to keep the coronavirus out.

The U.S. Air Force flight arrived Monday from Christchurch, New Zealand. The flight carried 106 passengers and crew, said Tony German. He is a representative for the U.S. Antarctic¹ Program. The program carries out U.S. scientific research activities.

Antarctica is the driest, coldest and windiest place on Earth. It is the world's only continent with no recorded cases of the coronavirus. A worldwide effort aims to make sure incoming scientists and workers do not bring the virus with them.

German told The Associated Press the new arrivals will start getting ready for Antarctica's upcoming summer season. The team will replace much smaller crews that spent the Southern Hemisphere's winter in Antarctica.

Monday's flight was delayed for three weeks by big storms. That meant the passengers had an extended², six-week quarantine. German said the crews were first isolated⁴ in San Francisco for four days. They then spent five weeks isolated in New Zealand, where they received several coronavirus tests during their stay.

On their arrival at McMurdo Station - the main U.S. base in Antarctica – all crew members will still be required to wear face coverings for two weeks. "We are being meticulous⁵ to ensure nothing happens," German said.

If the virus does enter the station, German said measures have been established to test and isolate³ any infected individuals.

Still, the flight delays over recent weeks showed how difficult it can be to quickly remove people from Antarctica. German said it took more than a week for winter crews at McMurdo to remove snow from the storms and clear the runway.

The Boeing C-17 Globemaster that landed Monday afternoon was the first U.S. flight to arrive on the continent since early May.

Officials say unusual teamwork involving the U.S., China, Russia and other countries took place this year in an effort to keep the virus out. All countries are planning to reduce numbers at their stations for the summer. The number of people at McMurdo is set to reach 450 this summer. That is about one-third of the usual level.

Some planned research and building projects will be delayed. German said the main goals are to keep the stations running and prepare for next year's winter, while trying to do some science along the way. "The show must go on," he said.
