A district health officer in Uttar Pradesh receives data from a tuberculosis (TB) surveillance program showing 120 new TB cases diagnosed in a population of 100,000 during the year 2023. The same district has 280 total TB cases (new and old) identified in the same population at the end of 2023. The officer needs to assess whether TB control efforts are reducing the disease burden. What is the most appropriate next step to interpret these findings and guide TB control strategy?
