A Nigerian tourist was quarantined at the Shaare Zedek Medical Center in Jerusalem Friday after doctors suspected she may have contracted the deadly Ebola virus, which is believed to have claimed hundreds of lives since the disease’s most recent outbreak in February.

The tourist, who arrived in Israel on Wednesday, admitted herself to the hospital after suffering from high fever. The medical team at the site decide to place her in a quarantined department after discovering that she had worked in Nigeria’s public health system and had come in contact with patients at local hospitals, Walla reported.

The Ebola epidemic, which emerged in Guinea at the start of the year before spreading to Liberia, Sierra Leone and Nigeria, is the worst outbreak since the hemorrhagic fever was first identified in 1976. More than 3,000 people appear to have been infected, and 1,552 have died, according to the latest World Health Organization figures.

Last month, the Foreign Ministry published a warning urging Israelis against travel to Liberia, Guinea and Sierra Leone.
