A patient is being tested for the Ebola virus at the University of Pennsylvania Hospital in Philadelphia.
"Conclusive testing has confirmed that the patient under evaluation at the Hospital University of Pennsylvania is not infected with Ebola virus", Greg Richter, a senior communications officer for the medical centre, said in a written statement.
P.J. Brennan, MD, Penn Medicine's CMO, said preliminary testing found the patient has another condition.

The tests have not yet shown Ebola, he said.
It's unclear whether the patient had traveled to a place that is now experiencing an outbreak of the disease, like the Democratic Republic of Congo, or came into contact with someone who is infected. "This can occur when a person touches the infected body fluids (or objects that are contaminated with them), and the virus gets in through broken skin or mucous membranes in the eyes, nose, or mouth".More news: 68mn girls at risk of genital mutilation by 2030 says WHO
