Infectious Diseases Blog

In outbreaks and other situations, there is a need for reliable rapid communications and for the ability to tap into relevant expertise. This need is not well served by peer-reviewed publications because of the slow turn-around time. At UNSW, we are well placed to provide such a service, as infectious diseases epidemiology is a major area of research strength. We teach major courses and degrees in infectious diseases, and are involved in leading international research in this field. I have started this blog for rapid, topical information on infectious diseases, with a focus on outbreaks, emerging infections, epidemiology, vaccines and vaccine-preventable diseases. I am committed to responsible blogging, which means all posts are by people qualified to write about the particular topic, or that blogs will be reviewed by relevant experts where required. All contributions are welcome, and will be reviewed/moderated. Comments on blogs are moderated.
