The person with Europe’s first confirmed case of Ebola is on the mend.

Teresa Romero, the Spanish nurse that contracted Ebola, has tested negative for the virus, according to multiple reports. Further tests will be necessary to determine whether Romero is indeed cured, but the news is another positive sign after she responded well to treatment.

Romero caught the virus while treating Spanish missionaries who had been working in West Africa. The nurse said she made a mistake in removing her protective suit, and touching her face with her gloves still on, which could have caused her to contract Ebola.

“I think the error was the removal of the suit,” Romero said, according to Spanish newspaper El País. “I can see the moment it may have happened, but I’m not sure about it.

Romero’s husband was quarantined and her dog euthanized as precautions against spreading the disease.

The news follows other positive indications that Ebola cases in the developed world are under control. The city of Dallas noted earlier on Sunday that it had not seen any new cases among those on its watch list.

U.S. President Barack Obama also rejected calls for a travel ban to West Africa, and urged people to remain calm. “This is a serious disease, but we can’t give in to hysteria or fear because that only makes it harder to get people the accurate information they need,” he said in his weekly address.
