US Forces Korea said Sunday it has instituted a 14-day self-quarantine for US service personnel who visited China recently as the new coronavirus outbreak continues to spread.

The quarantine measures, effective as of Sunday, are for US service members returning from China to South Korea on or after Jan. 19, "out of an abundance of caution to mitigate risk to the USFK population," the military said.

The implementation applies only to US soldiers who reside on or off USFK installations, and the 14-day quarantine, which equals the incubation period for the novel virus, begins from the date an individual returns to South Korea regardless if they display symptoms or not, according to the USFK.

The imposition is in line with the US Health and Human services' announcement of a US public health emergency related to the pneumonia-like illness, as well as the South Korean military's actions of isolating recent returnees from China, it added.

"USFK does not have any personnel who have returned from Wuhan or Hubei province, the epicenter of the novel coronavirus outbreak since Jan. 19," the military said in a release.

As of noon on Sunday, South Korea had reported 15 confirmed cases of the deadly virus. No suspected or confirmed cases have been reported among South Korean and US soldiers, according to officials. (Yonhap)
