Health officials in Ohio are monitoring more than 100 people following the visit by a Dallas nurse who tested positive for Ebola shortly after returning to Texas from the Cleveland area.

Officials said Saturday that none of those being monitored are sick.

State officials previously said 16 people Amber Vinson had contact with were being monitored. Officials say the sharp increase is a result of the identification of airline passengers who flew with Vinson between Dallas and Cleveland and the identification of people who also visited the dress shop where her bridesmaids were trying on dresses.

Vinson's stepfather is quarantined in his home in the Akron suburb of Tallmadge. That is where Vinson stayed during her visit.

The stepfather is the only person in the state under such a restriction.
