A Canadian man hospitalized earlier this week because he was at risk of having the deadly Ebola virus was discharged from a Tokyo hospital Thursday with a clean bill of health, the health ministry said.

The man, identified as a journalist who had spent two months in Liberia since Aug. 18, tested negative for the virus in two tests, the second of which was conducted on Wednesday, and is in good condition, the Health, Labor and Welfare Ministry said.

After arriving with a fever Monday at Tokyo's Haneda airport from London, the man was taken to the National Center for Global Health and Medicine in Shinjuku Ward for testing after concerns rose about his risky travel history, which he declared at the airport's quarantine station.

He was found to have a fever of 37.8 degrees, versus the average normal temperature of around 36.8.

On Tuesday, the ministry said the man tested negative and that his body temperature returned to normal, although he remained hospitalized for further observation.

There is no cure or effective treatment for the Ebola virus, which has a fatality rate above 50 percent. The virus has been running rampant in West Africa and in an unrelated outbreak in the Democratic Republic of Congo, in central Africa.
