Topics and Outlines     (NOTE!  * = Required reading)
 Note: The lecture outlines and required readings will be available for purchase as CLASS NOTES at the UA Bookstore

Each topic outline below can be used to follow along with the lecture. The outlines contain the topics, mostly in order, that are covered in class. In addition, each outline has study questions and a case history for review.You should be able to answer these questions and fully understand the case history. The questions and some of the cases will not be specifically covered in class, but you can bring up the questions in class if you wish. Available here are the case histories from all the outlines, all of the questions from the outlines, and brief answers.  In addition, you may find the study guide questions, drawn from previous exams, very useful.
You are expected to read the 1-2 items with an "*" before the lecture, either from the on-line version or the printed version, available as a class packet at the bookstore. Other items listed below are optional (and not included in the printed packet) and interesting. If you are curious about the virus that is presented in class you can learn more about that group of viruses by clicking on the virus family name. The exam questions will be derived from the lecture and required reading only.
