Monning was transported to a hospital where it was determined that he did not have the virus.
Patients at the practice in Braintree, about 12 miles south of Boston, were also held briefly on Oct. 12 while the man who had been to West Africa was taken to a hospital, where it was determined he did not have Ebola. The car that he drove to the office was decontaminated by crews in hazmat suits.
CDC Director Tom Frieden said the agency is bolstering training nationwide on how to respond to an Ebola case.
U.S. health care has become more complex with retail clinics, urgent care centers, work-site clinics and even online clinics, so ensuring that everyone strictly follows protocol is going to continue to be a challenge.
But that’s not necessarily a bad thing, said Dr. Tom Zweng of Novant Health, a four-state system based in Winston-Salem, North Carolina.
"This is not an exercise in futility," he said of the measures being taken to protect against Ebola. "This is preparing staff in safe practices. It may be Ebola today, but tomorrow there may be another communicable disease that we don’t even know about. This is about taking health care in this country to the next level."
