Thomas Duncan, a 42-year-old Liberian citizen, is in serious condition with Ebola in a Dallas hospital. His partner Louise is confined to the Dallas apartment where Duncan became very sick from the virus. Texas health officials have placed her, one of her children, and two nephews in their 20s, under quarantine. This means they have been ordered, under threat of prosecution, by the county not to leave their home or have any contact with outsiders for 21 days. Any exception requires the approval of the local or Texas state health department.
