ABC News chief health and medical editor Dr. Richard Besser called the case concerning, adding that public health officials will need to investigate how the exposure occurred. While the CDC has said that any hospital is capable of safely treating Ebola, Besser said health care workers need training and practice using protective equipment to do so successfully. "I would never have gone into an Ebola ward in Africa without being dressed and decontaminated by experts," he said. "Health care workers here should expect no less."
About the underlined part, does it mean that Besser had gone into an Ebola ward in Africa without being dressed and decontaminated by experts before,and if he had known the case earlier, he would not have done that?
No, it simply means that he would not have gone into an Ebloa ward in Africa without being dressed and decontaminated by experts in the past. He wouldn't then and he wouldn't now. If he had said "I would have gone into an Ebloa ward...", that would mean that he would have gone, but with the never, he is saying that it is something which he wouldn't do.
