Derek Wong is a medical virologist in Hong Kong who worked in the lab that discovered the first-ever human avian influenza infection (H5N1), and he has studied SARS as well. Putting his credentials to work, Derek created Wong's Virology, a web site full of information about viruses, directed largely toward undergraduate and post-graduate students. The site includes practice exams aimed at students of multiple levels. Best of all, Wong's Virology provides excellent summaries of virus information in an easy to access fashion.
