MADRID (AP) — Madrid’s regional government says it’s going to kill the pet dog of a Spanish woman who became infected with Ebola.

Authorities said in a statement Tuesday that available scientific knowledge indicates there’s a risk the dog could transmit the deadly virus to humans.

The Spanish nursing assistant became the first case of Ebola being transmitted outside of West Africa after she cared for a Spanish priest in Madrid who died of Ebola last month. She and her husband are now in quarantine.
