[11][12] On 7 October, Madrid's regional government got a court order to euthanize Romero's pet dog, Excalibur, concerned that it posed a risk as a reservoir host.

Ramos' quarantined husband, Javier, called on a veterinarian radio show host, and recorded a video appeal, for help to save his dog.

According to one report, the improvement may be attributed to Romero's having received the experimental drug ZMab which is similar to ZMapp, which has been used to treat several Ebola patients.

However, according to information released by Spain's Centre for Health and Emergency Alerts, the nurse did not receive ZMab due to concerns over possible side-effects.

On November 1, it was announced that she was Ebola-free, and had been moved out of the isolation ward into a normal hospital bed to finish the process of recuperation from her illness.
