Three schools in Texas and two in Ohio have opted to shut down to be disinfected after learning that their students or staff were either on the same Cleveland-to-Dallas flight or aircraft as Amber Joy Vinson, the nurse who tested positive for Ebola yesterday.

Belton Independent School District Superintendent Susan Kincannon announced today that a student at Sparta Elementary School and a student at North Belton Middle School were on the same flight as Vinson and attended classes Tuesday and Wednesday.

Both schools and the district's Belton Early Childhood School will be closed to be properly cleaned. The parents of the students who flew with Vinson on Frontier Airlines have decided to keep them home from school for 21 days (the maximum incubation period for Ebola), the New York Times reports.

Although Vinson's fellow passengers have been deemed by CDC director Dr. Thomas R. Frieden as having an "extremely low" chance of contracting the virus, school districts choosing to close schools have said they are doing so as purely precautionary measures. "The health and safety of our students is my first priority," Kincannon said in the statement.

Solon Middle School and Parkside Elementary School in Solon, Ohio will be closed Thursday as "a willing precaution" after the district learned that a staffer at the middle school flew on the same aircraft, but not the same flight, as Vinson.

In addition to the school closures, a number of hospitals in Ohio have placed members of their staff who flew with Vinson on her initial flight from Cleveland to Dallas on paid leave. From the Times:

And officials of two major health systems in Cleveland — the Cleveland Clinic and MetroHealth — said that a group of nurses had been placed on leave because they were aboard Ms. Vinson's first flight, from Dallas to Ohio, on Friday.

"The decision to put those nurses on paid leave really has to do with decreasing anxiety," Dr. Jennifer Hanrahan, the chairwoman of MetroHealth's infectious disease control committee, said at a news conference. "It's not because of any perceived risk to them or to anyone."

Aultman Hospital in Canton, which had five nurses aboard the flight, said it would also place employees on leave. "As a further precaution, we have reviewed the assignments of those five nurses and identified the patients in their direct care," the hospital said in a statement. "We are in the process of contacting those patients to make sure they are fully informed."

Vinson was among the staff at Texas Health Presbyterian Hospital to treat Ebola-stricken Liberian citizen Thomas Eric Duncan, who died from the virus last week.
