MADRID, Oct. 17 (UPI) —

An Air France passenger hospitalized with Ebola-like symptoms after his plane arrived in Madrid tested negative for the Ebola virus, Spain’s Deputy Prime Minister announced Friday.




The unidentified man, a Nigerian citizen, traveled from Lagos, Nigeria to Paris and then to Madrid Thursday, and left the plane with shivering and fever.




Three other suspected Ebola cases in Spain — a health care worker who traveled in an ambulance with nurse Teresa Romero, who contracted the disease; a Spanish cleric who recently returned from missionary work in Liberia; and a Red Cross nurse who worked in Sierra Leone — were declared virus-free after a preliminary test.




"All the patients that checked in on Thursday have tested negative," Deputy Prime Minister Soraya Sà ¡enz de Santamarà ­a said Friday.




All four patients will remain hospitalized until a second test, 72 hours after the first, confirms they are without the virus.




Spain has 21 people currently quarantined, many of whom are health care workers who treated Romero.
