Physicians in training are taught to recognize these viruses even though they had not been a big problem for years.
Dr. Steven Herrine, vice dean for academic affairs and undergraduate medical education at Thomas Jefferson University, says that's why doctors are taught the skills to find that last piece of the puzzle.
"We also need to train students to think and to be able to problem solve. It's not so difficult now to look up information everybody has in their pocket, a computer that can look up information easily. The question is what is the quality of that information and how is it applied to medical problems and taking care of patients and populations," Herrine said.
He says students must also be taught the skills to listen to a patient's concerns about vaccines and then address the issues.
