New sites I refer to include:

The Just-in-time Swine influenza lecture
As a result, here it is: “Just-in-Time Lecture: Swine influenza A (H1N1) Outbreak in US & Mexico: Potential for a Pandemic,” by Rashid A. Chotani. Uniformed Services University of the Health Sciences (USUHS). Updated daily. The html and powerpoint versions are available at this Supercourse site at the WHO Collaborating Center, University of Pittsburgh.
