A woman who has been confined to her Dallas apartment under armed guard after a man infected with Ebola stayed at her home, said she never imagined this could happen to her so far from disease-ravaged West Africa.

Louise Troh said on Thursday that she is tired of being locked up and wants federal health authorities to decontaminate her home.

Authorities say the circle of people in the United States possibly exposed to Ebola widened after the man, who arrived from Liberia last month, was discharged from a hospital without being tested for the deadly virus.
