BEIJING (AP) — For a country determined to keep out the virus that first emerged within its borders, bringing in more than 15,000 people from all corners of the world was a serious gamble. It appears to be working.

One week into the 17-day event, China seems to be meeting its formidable COVID-19 Olympic challenge with a so-called “bubble” that allows Beijing Games participants to skip quarantine but tightly restricts their movement so they don't come in contact with the general population. There have been 490 confirmed cases — many of them positive tests on symptomless visitors — and no reports of any leaking out to date.
