One of five prisoners receiving treatment for a suspected case of Ebola virus in Uganda escaped overnight Friday from the hospital at the center of the outbreak, a health official said.

"Should his results come back and he is positive, that causes us a lot of worry. So right now, we have resolved that the remaining prisoners will be cuffed on the beds for fear that they might also escape," said Dr. Jackson Amune, commissioner at the Ministry of Health.

The five inmates from Kibaale prison are among 30 people at Kagadi hospital with suspected cases of the virus. Two additional patients have confirmed cases, according to Doctors Without Borders.
