ARI (Annual Risk of Tuberculosis Infection)
New smear +ve estimated case = ARI x 50 x Defined Population/100,000
ARI would be occure in different areas
(For example FY 2065/2066)
Urban = 3.16
Terai = 2.16
Hill = 1.16
Mountain = 0.76
National = 1.51
Example :
District : Rupandehi
Population (1995) : 622576
Incidence of sputum +ve according to the formula
ARI x 50 x Defined Population/100,000
2.16 x 50 x 622576 /100,000 = 1093 (total estimated case)
New smear +ve estimated case = ARI x 50 x Defined Population/100,000
