An Italian doctor, who contracted Ebola in West Africa, has returned to Rome and is receiving treatment with an experimental drug.

According to the Associated Press, the drug being administered is the same one that the U.S. and other European countries have used to treat patients with in the past.

Bloomberg News noted that the doctor, whose name has not been released, was admitted to the Lazzaro Spallanzani National Institute for Infectious Diseases. There, he will be treated by a team of about 30 volunteer doctors and nurses.

As previously reported, he was infected with Ebola while working abroad in Sierra Leone with the humanitarian group Emergency.

The often-fatal virus has killed upwards of 5,400 people, mostly in the West African countries of Sierra Leone, Liberia and Guinea, since March. It is the worst outbreak in history.

The disease is spread through direct contact with blood and body fluids of an infected party.

The doctor is the first confirmed case of Ebola in Italy.
