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).
In the UK, a single rare disease may affect up to about 30,000 people. The vast majority of rare diseases will affect far fewer than this â some will affect only a handful, or even a single person in the whole of the UK. 80% of rare diseases have a genetic component. Often rare diseases are chronic and life-threatening.
