They've started rejecting Nigerian students admission because of Ebola?

Despite being an Ebola-free country, some universities in the US are now rejecting Nigerian students admission. Twitter user @Idrisayobello shared one of those rejection letters on twitter and wrote, "Ironic that NavarroCollege only 31 miles away from Dallas with an active #Ebola case is denying admission to Nigerians who are ebola-free!". This is ridiculous!
