BEIJING, Aug. 26 -- China's health authorities confirmed on Tuesday that a returnee who was hospitalized as "an observation case of Ebola" has been confirmed not infected.

The National Health and Family Planning Commission told Xinhua the returnee, a translator who arrived in Beijing on Sunday from Libya, developed symptoms of vomiting and fever, and was sent to the hospital as a precaution.

The patient has since been cleared as not infected with Ebola. China currently reports no case of the disease.

According to the commission, people whose body temperature exceeds 37.3 degree centigrade and have had contact with patients or animals with Ebola symptoms in affected areas within 21 days should be isolated and treated early.

The commission, together with the Ministry of Public Security, the General Administration of Customs, the General Administration of Quality Supervision, Inspection and Quarantine, the Civil Aviation Administration and State Administration of Traditional Chinese Medicine, have set up five supervision groups.

They have been sent to Beijing, Shanghai and provinces of Jiangsu, Zhejiang, and Guangdong to carry out supervision and inspection in key areas for precaution.
