The following statistics relate to the prevalence of Tuberculosis:
The following statistics relate to the incidence of Tuberculosis:
The following statistics relate to deaths and Tuberculosis:
The term 'prevalence' of Tuberculosis usually refers to the estimated population
of people who are managing Tuberculosis at any given time.
The term 'incidence' of Tuberculosis refers to the annual diagnosis rate,
or the number of new cases of Tuberculosis 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.
