(CNN) -- A nurse's aide in Spain catches Ebola; her dog is taken away and put to death. A nurse in Texas catches Ebola; her dog is fed, taken away and put into quarantine. The stark difference in treatment illustrates the lack of solid protocol on what to do with Ebola victims' pets -- and highlights what little is known about the risk. Why are we even talking about this? Focusing on the cases of two dogs can seem trivial compared to the 4,000 people in West Africa who have died from Ebola this year. But CNN's Anderson Cooper notes that concern about animals can have a broader impact on human health.
