Prevalence and Incidence of Psittacosis
Psittacosis: Rare Disease
Psittacosis is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Psittacosis, or a subtype of Psittacosis,
affects less than 200,000 people in the US population.
Incidence (annual) of Psittacosis:
16 annual cases notified in USA 1999 (MMWR 1999) ... see also overview of Psittacosis.
approx 1 in 17,000,000 or 0.00% or 16 people in USA [Source statistic for calcuation: "16 annual cases notified in USA 1999 (MMWR 1999)" -- see also general information about data sources]

Prevalance of Psittacosis:
Since 1996, fewer than 50 confirmed
cases were reported in the United States each year. Many more
cases may occur that are not correctly diagnosed or reported. (Source: excerpt from Psittacosis: DBMD)
Incidence statistics for Psittacosis:
The following statistics relate to the incidence of Psittacosis:
- 1.0 new cases of ornithosis per 100,000 population was notified in Australia 2002 (Yohannes K, Roche P, Blumer C et al. 2004, Australia’s Health 2004, AIHW)

About prevalence and incidence statistics:
The term 'prevalence' of Psittacosis usually refers to the estimated population
of people who are managing Psittacosis at any given time.
The term 'incidence' of Psittacosis refers to the annual diagnosis rate,
or the number of new cases of Psittacosis diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
