Two passengers who spoke to News4 say the woman got onto the bus around 9:10 a.m. and got sick in the bathroom. She then got off the bus and vomited in the south parking lot in the area of lanes 17-19.  The woman allegedly indicated to a passenger that she had recently traveled to West Africa, according to a statement released by the Pentagon. The woman was initially taken to Virginia Hospital Center but did not leave the ambulance there. She was then transported to Fairfax Inova Hospital.More
