Investigations are under way at a hospital in Madrid after a Spanish nurse became the first person known to have contracted the deadly Ebola virus outside west Africa.
The nurse had treated two Spanish missionaries who died of the disease after being flown home from the region.
The 40-year-old nurse was part of the Madrid team that treated Spanish priests Manuel Garcia Viejo and Miguel Pajares, who both died of the virus, Spanish officials say.
The hospital Carlos III de Madrid where the priests were treated is reported to have had extreme protective measures in place including two sets of overalls, gloves and goggles.
The nurse is in a stable condition and has been moved from the Alcorcon hospital to a specialised unit at the Carlos III hospital.
The other members of the medical team are being monitored.
Manuel Garcia Viejo, 69, died on 25 September after catching Ebola in Sierra Leone.
Miguel Pajares, 75, died in August after contracting the virus in Liberia.
The nurse began to feel unwell on 30 September, but only sought medical advice on Sunday.
