The federal government is ramping up its response to the Ebola crisis after a second Dallas nurse became ill and was diagnosed with the virus after flying from Cleveland to Dallas.
Ebola patients are not considered contagious until they have symptoms. The virus is spread through direct contact with bodily fluid.
Still, the revelation of another Ebola infection has raised alarms, and many of them right here in Northeast Ohio.
The biggest question on people's minds -- why was this woman allowed to fly?
She had direct contact with Thomas Eric Duncan, the Liberian man who died in Dallas.
The nurse, Amber Vinson, 29, flew from Dallas/Fort Worth to Cleveland on Oct. 10, just two days after Duncan died. Vinson had taken intimate care of him.
A government source now says Vinson called the CDC before her return trip to report an elevated temperature of 99.5 degrees.
The CDC doesn't consider a fever a symptom of Ebola until it hits 100.4.
Vinson then made the return flight on Oct. 13, still with that low grade fever.
She was diagnosed with the disease on Wednesday.
Health officials are reminding people the risk of contracting the virus in Ohio is very small.
Still, out of an abundance of caution, they want to talk to anyone who was on Vinson's Frontier Airlines flight 1143 on Monday to Dallas. Passengers should call 1-800-CDC-INFO.
Frontier Airlines placed six crew members on paid leave for 21 days out as a precautionary measure.
