Somehow I stumbled across Chikungunya Virus Net the other day, and thought it was useful enough to include in the News Gatherers list. At once I found it was providing the most (and most recent) news; most of my chikungunya posts for the last couple of days have come from it.
Belatedly I started exploring the site a few minutes ago and discovered it's run by Dr. D. A. Beleijs in the Netherlands. He's also the creator of Dengue Virus Net and Influenza Virus Net, both of which are now in the News Gatherers list also. (He also runs Gene Therapy Net, which is a bit outside my bailiwick.)
The moral of this story: When you discover an interesting site, explore its links. Poke around in its closets and snoop in its medicine chest and desk drawers. You may find some extremely useful resources.
