AKIPRESS.COM - A Cleveland area school has taken a series of precautions after learning that one of its teachers may have come in contact with a nurse from Dallas who has since been diagnosed with Ebola.

In written statement, the Cleveland Metropolitan School District (CMSD) said it was informed late Wednesday night that "a teacher who works at Cranwood School may have come in contact with a person diagnosed with the Ebola virus."

While the statement did not confirm the Ebola patient's identity, officials confirmed early Wednesday morning that a nurse from Dallas, Texas tested positive for the disease not long after returning from the Cleveland area, where she visited family members. No other known Ebola cases have been reported in the Cleveland area since the current outbreak of the disease this summer in West Africa. So far, the outbreak has claimed about 4,500 lives -- almost all of them in Liberia, Sierra Leone and Guinea.

Dallas nurse Amber Vinson -- the second health care worker at Texas Health Presbyterian Hospital to contract the disease while treating a Liberian man who died at the facility after traveling to West Africa -- flew home to Dallas from Cleveland's Hopkins International Airport on Oct. 13 before she began exhibiting clear symptoms of the deadly virus.

However, as CBS News' Jon LaPook reported Wednesday evening, Vinson called the Centers for Disease Control and Prevention (CDC) several times before flying, saying that she had a fever with a temperature of 99.5 degrees. But because her fever wasn't 100.4 degrees or higher, she didn't officially fall into the group of "high risk" and was allowed to fly.

One health official told CBS News that, put bluntly, "somebody dropped the ball" in telling Vinson it was safe to travel.

The statement from the CMSD did not explain how or when Vinson might have come into contact with a teacher from the Cranwood School, a feeder school for 9th graders heading into the larger JFK High School, southeast of central Cleveland.

The school district said Cleveland health department officials had assured them "our students, families and staff are not at risk," but added that some precautions were taken regardless, "to allay any concerns about safety at Cranwood School."
