Nurses at the Dallas hospital that treated the Liberian man, Thomas Eric Duncan, who died from Ebola last week say there were no protocols in place, according to an article on the CNN website. The nurses' union said guidelines were constantly changing on how to deal with the virus. 

Two healthcare workers have been infected at Texas Health Presbyterian Hospital.

"The protocols that should have been in place in Dallas were not in place, and that those protocols are not in place anywhere in the United States as far as we can tell," National Nurses United Executive Director RoseAnn DeMoro said in the article. 

Union officials did not specify how many nurses they had spoken with at Texas Health Presbyterian. The nurses at the hospital are not members of a union, officials said.

The nurses' alleged, among other things, that Duncan wasn't immediately isolated and at one point during his care, hazardous waste piled up.

"There was no one to pick up hazardous waste as it piled to the ceiling," union co-president Deborah Burger said. "They did not have access to proper supplies."
