"If you, your child, a member of the household or a close personal contact have traveled to an impacted country the child must remain out of the child care center or school for a period of 21 days from the date they departed the affected country," the notice said.
Robert Wheeler, chief medical officer of On Call International, said he agrees with Bright Horizons' decision.
"This is a reasonable public health directive and is consistent with the CDC guidance for people with potential Ebola virus exposure," Wheeler said. "Early symptoms in young children may not be detected in a timely fashion, allowing for the potential exposure of other children" to the Ebola virus.
He said all travelers returning from countries affected by the current Ebola epidemic should self-monitor themselves for symptoms for three weeks, which is the extent of the incubation period—the time from infection with the virus to the onset of symptoms.

Ebola has sickened more than 7,000 people and killed over 3,300 people in West Africa.
The Centers for Disease Control and Prevention confirmed that the first case of Ebola, which spreads through direct contact with an infected individual's body fluid or organs, was diagnosed in the U.S. on Tuesday.
The patient, who arrived in Dallas from Liberia, came in contact with multiple school-age children in the state who are currently being monitored for symptoms, according to Texas Gov. Rick Perry.
Bright Horizons operates several child care and education facilities in the Dallas area.
