Dean of the College Rakesh Khurana wrote in an email Monday that there have not been any confirmed cases of the Ebola virus on campus or in the region, just hours after Boston medical workers initiated a second quarantine in as many days for individuals suspected of exhibiting Ebola-like symptoms.

“I have been moved by the loss of life and by the courage of those who have selflessly offered their help,” wrote Khurana, recommending that students call University Health Services if they have concerned about their health.

On Sunday, officials quarantined a medical facility in Braintree for hours before doctors cleared a man feared to have been infected by the deadly virus. Workers in hazmat suits at Logan International Airport escorted five passengers exhibiting flu-like symptoms off an Emirates flight, just a day later. The Ebola outbreak, the largest in history, has affected more than 8,000 people in West Africa since March, with more than 4,000 people dead from the disease.
