Prevalence and Incidence of Leptospirosis

Leptospirosis: Rare Disease

Leptospirosis is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Leptospirosis, or a subtype of Leptospirosis, affects less than 200,000 people in the US population.

Ophanet, who are a consortium of European partners, currently defines a condition rare when if affects 1 person per 2,000. They list Leptospirosis as a "rare disease". More information about Leptospirosis is available from Orphanet

Incidence (annual) of Leptospirosis:

100-200 cases annually in USA (DBMD) ... see also overview of Leptospirosis.

Incidence Rate:

approx 1 in 2,720,000 or 0.00% or 100 people in USA [Source statistic for calcuation: "100-200 cases annually in USA (DBMD)" -- see also general information about data sources]

Incidence extrapolations for USA for Leptospirosis:

99 per year, 8 per month, 1 per week, 0 per day, 0 per hour, 0 per minute, 0 per second. [Source statistic for calculation: "100-200 cases annually in USA (DBMD)" -- see also general information about data sources]

Prevalance of Leptospirosis:

It is estimated that 100-200 cases are identified annually in the United States with about 50% of cases occurring in Hawaii. (Source: excerpt from Leptospirosis: DBMD)

Incidence statistics for Leptospirosis:

The following statistics relate to the incidence of Leptospirosis:

  • 0.8 new cases of leptospirosis per 100,000 population was notified in Australia 2002 (Yohannes K, Roche P, Blumer C et al. 2004, Australia’s Health 2004, AIHW)
  • 155 new cases of leptospirosis 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 Leptospirosis usually refers to the estimated population of people who are managing Leptospirosis at any given time. The term 'incidence' of Leptospirosis refers to the annual diagnosis rate, or the number of new cases of Leptospirosis 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. For more information see about prevalence and incidence statistics.
