What Is Parrot Fever? Parrot fever, also called parrot disease and psittacosis, is very rare. According to the Centers for Disease Control and Prevention, there have been fewer than 50 confirmed cases per year in the United States since 1996, although many cases may have gone undiagnosed or unreported (CDC).
There are more than 7000 diagnosed rare diseases and many more undiagnosed diseases. About 1 in 12 people (nearly three million Canadians) have a rare disease. Most known rare disorders are severe and chronic, with many being degenerative and life threatening.
