A district health officer in Maharashtra is evaluating the burden of pulmonary tuberculosis (TB) in a district with a population of 200,000. On 1 April 2024, a prevalence survey identified 400 individuals with active TB (both newly detected and previously known). By 31 March 2025, the same population was re-surveyed and 420 individuals had active TB. During the 1-year period, 80 new cases of TB were diagnosed and 60 individuals with TB died. Assuming no migration, what is the incidence of TB per 100,000 population during the 1-year period (1 April 2024 to 31 March 2025)?
