This introductory virology course emphasizes the common reactions that must be completed by all viruses for successful reproduction within a host cell and survival and spread within a host population. The molecular basis of alternative reproductive cycles are presented with examples drawn from a set of representative animal and human viruses, although selected bacterial viruses will be discussed.

This offering has been a top-ten iTunes U Course in sciences pretty much since its release in 2012, with over 80,000 subscriptions. The course will be ported to the Coursera platform in two parts and will allow interested online students to take the course as a cohort for the first time.

John completed this course, spending 3 hours a week on it and found the course difficulty to be hard.
This is an amazing course taught by a leading virologist who is clearly very passionate about viruses, and his passion is contagious. I didn't realize how interesting and varied viruses were until I took this class (I also recommend virology II, how viruses cause disease), and I'm now quite fond of them. Having said that, this is a challenging course. Because it involves molecular biology, there are a number of genes, acronyms, and molecules that you are required to know. Expect a little bit of frustration from that, but the class more than makes up for it.
