Abbreviations: anti-HCV, antibodies against hepatitis C virus; HCV, hepatitis C virus; IR, incidence rate; NCDC, National Center for Disease Control; PY, person-year; TB, tuberculosis.

The high incidence rate of TB in 2020 is likely caused by the pandemic-related lockdowns in the first half of the year (March–May). Anti-HCV testing was lower in early months of 2020 and increased in summer, which caused the number of people included in the analysis for 2020 to increase but their contribution to person-time was very short and resulted in a small denominator, increasing the rate.
