Ebola's victims may soon include a dog. Officials in Madrid want to euthanize the dog of a Spanish nursing assistant with Ebola because of the chance the animal could spread the disease.
At least one major study suggests that dogs can be infected with the deadly virus without having symptoms. But whether or how likely they are to spread it to people is less clear.
Lab experiments on other animals suggest their saliva or excretions might contain the virus. The head of the Centers for Disease Control and Prevention says it's important to look at all possibilities.
The Spanish nursing assistant and her husband have been in isolation since she tested positive for Ebola earlier this week.
