Two Japanese who had been subject to home quarantine in South Korea for Middle East respiratory syndrome were back in Japan as of Monday, a source close to Japan-South Korea relations said.
They are believed to be among 20 to 30 foreign nationals who senior South Korean health ministry official Kwon Jun-wook said have been subject to home quarantine. None showed symptoms and all have tested negative for the virus, according to the South Korean official.
It remains unknown why the two Japanese could be repatriated when South Korea has banned people under quarantine to leave the country. The pair may have left before they were notified of the quarantine measure.
