Dallas County Health and Human Services Director Zachary Thompson said that these people are not being watched or monitored and are not showing any symptoms of the illness. Only the immediate family members of the victim are being regularly monitored for Ebola symptoms; they've been ordered to stay at home and avoid contact with others.
On Wednesday, Texas officials initially said that they believed the man had contact with 12 to 18 people, including five children who attended four different schools in the Dallas area.
"Now the number has increased in terms of number of contacts," Thompson said in a phone interview. "The only [people] closely monitored at this point are the family members."
On Wednesday night, Duncan's family members received an order requiring them to stay home and comply with blood tests for the duration of the virus's potential 21-day incubation period.
Thompson said that the control order was necessary "to ensure compliance."
