Health official: Ohio quarantine numbers could grow

Officials have now identified 16 people, up from 12, who came into close contact with Ebola patient Amber Vinson. The person at highest risk is her stepfather, who is now under strict quarantine.

Vinson traveled from Dallas to Cleveland and back last week on Frontier airlines.

Frontier has finished notifying some 800 passengers who flew on either of her two flights, as well as those who traveled on those same planes, about Vinson's diagnosis.
