Now that you've started research on your disease topic, here are some resources that you might find helpful. These sites should provide you with solid background information for your disease, beyond the basic web "consumer" sites.
Centers for Disease Control and Prevention
National Institutes of Health
World Health Organization
Once you get beyond the basics, you'll need to look online for newspaper and magazine sources. Some places to check:
NCCS Library page for Database searches
iCONN Library search
New Canaan Library research page: you'll need to enter your library card number to access this. Or use your local library's resources. If you don't have a library card, get one.
