According to this link, he may have come into
contact with 80 people.
Hospital sent Ebola-infected patient home
......."On Thursday Zach Thompson with Dallas County Health and Human Services told News 8 that the man may have come into contact with 80 people. Four to five people are being closely monitored and they have been put under a "control order" to stay inside their home. All of them are close family members."...............
Thank you. The one thing, though, is that Zachary might walk back this statement. He spoke out of turn yesterday, then everyone denied what he said (he said there was a person they thought had Ebola that they were watching)
