I recommend without hesitation Gloria Rivera's webinar, The Medical History. It is so good to be respected and taken seriously as a professional medical interpreter. We don't have to be doctors or nurses, but as medical interpreters we need familiarity and facility with medical terminology in both languages, as well as a solid understanding of the human body, its functions, and common illnesses. Be alert and take good notes! There is much more to the medical history than just running down a list of questions; this course helps you dig into the details.
