TAIPEI -- Taiwan's disease control authorities said on Saturday that a 19-year-old man is suspected of being infected with the Ebola virus.

The man has developed symptoms of vomiting and diarrhea since he returned from Nigeria, where he had contact with animals, the authorities said.

He is now isolated in a hospital in Kaohsiung City, southern Taiwan. Samples have been sent to Taipei for examination, and authorities will announce the result this afternoon.

The authorities called on people to stay calm and have a check-up after returning from West Africa.
