Students sit on the ground after being cordoned off by police and barrier tape following an Ebola scare at Southwestern College in Chula Vista, California October 16, 2014. The abundance of caution had officials keeping students from leaving a section of the school after one of them reported her sister
became sick after returning from a trip. The school later released a statement saying the student's family had travelled to the Midwest, and that a nurse had examined the student and found no symptoms resembling Ebola.
