News that an arriving foreigner had been quarantined Monday spread quickly, and some travelers and greeters at Tokyo's Haneda airport were on edge. However, the place was running smoothly on Tuesday morning.

"I did hear that Ebola is not transmitted in the air, but still, I was scared until I found the man had tested negative," said a 54-year-old woman from Yokohama traveling with three friends to South Korea.

Some remained on edge. Sumiko Ito, 60, who was waiting to greet her daughter and grandchildren from a flight, was wearing a surgical mask. She said she had decided to take the precaution after hearing that the Canadian journalist had been tested for Ebola.
