No confirmed Ebola infection cases have entered the Chinese mainland as of Tuesday, China's top inspection and quarantine authority announced on Wednesday.

Inspection and quarantine authorities at entry ports across the country inspected 26,235 people coming from Ebola-affected areas between Aug 4 and Tuesday. The authorities identified 88 people displaying symptoms of fever, but no cases of Ebola infection was found, the General Administration of Quality Supervision, Inspection and Quarantine said on Wednesday.

The authorities also inspected and quarantined more than 1,400 flights and 6,126 batches of goods coming from the areas during the same period.

The administration has ordered its offices at various levels in China to intensify efforts to prevent the deadly disease from spreading to China. Recently, the virus has spread to parts of the United States and Europe.

Measures taken include requesting governments in affected West African countries to intensify quarantines for outbound travelers and requesting China-bound international flights to broadcast videos of Ebola prevention that the administration produced, the administration said.
