Three people have been admitted to hospital in Madrid, and another one in Tenerife, all suffering symptoms of Ebola.
All four have high fevers and have been in at risk areas.
Of the Madrid three, one is a friend of nurse Theresa, who is recovering from Ebola in hospital; one is a man who arrived from Paris today, having recently been in Africa and who has a high fever; and the third is a missionary who has just returned from Sierra Leon.
And the Tenerife man is a Red Cross worker who has returned from Sierra Leon. Tenerife has activated its Ebola protocol, and has isolated the mans wife and son, although so far they do not have any symptoms.
