Objectives Although evidence is growing on the overall impact of the COVID-19 pandemic on tuberculosis (TB) services, global studies based on national data are needed to better quantify the extent of the impact and the countries’ preparedness to tackle the two diseases. The aim of this study was to compare the number of people with new diagnoses or recurrence of TB disease, the number of drug-resistant (DR)-TB, and the number of TB deaths in 2020 vs 2019 in 11 countries in Europe, Northern America, and Australia. Methods TB managers or directors of national reference centers of the selected countries provided the agreed-upon variables through a validated questionnaire on a monthly basis. A descriptive analysis compared the incidence of TB and DR-TB and mortality of the pre-COVID-19 year (2019) vs the first year of the COVID-19 pandemic (2020). Results Comparing 2020 vs 2019, lower number of TB cases (new diagnosis or recurrence) was notified in all countries (except USA-Virginia and Australia), and fewer DR-TB notifications (apart from France, Portugal, and Spain). The deaths among TB cases were higher in 2020 compared to 2019 in most countries with three countries (France, The Netherlands, USA-Virginia) reporting minimal TB-related mortality. Conclusions A comprehensive evaluation of medium-term impact of COVID-19 on TB services would benefit from similar studies in multiple settings and from global availability of treatment outcome data from TB/COVID-19 co-infected patients.
