Liberia said it plans to prosecute Thomas Eric Duncan, who brought Ebola to the U.S., for allegedly lying on a health form, stating he hadn't come into contact with anyone suffering from the highly contagious virus, the BBC reported Thursday. Duncan was diagnosed with Ebola on Tuesday at a Dallas hospital.

There was no further information about Liberia’s plans to put Duncan through its justice system. The Liberian man was in serious but stable condition at Texas Health Presbyterian Hospital in Dallas as of Thursday morning local time, according to the hospital.

 “We are making sure that the caregivers and other critical functions that enable us to care for patients safely are being fully supported by Texas Health Resources,” hospital officials said. “The safety of patients, employees, physicians, volunteers, visitors and community is our top priority.”

So far, there's no indication that Ebola in the U.S. has spread from Duncan to others, although health officials estimated he came in contact with about 100 people. Duncan flew to Dallas from Liberia with a layover in Brussels.

Duncan’s family in Texas has been ordered to remain in their home by the Texas Department of State Health Services. The family already disobeyed the order, Reuters reported.
