Introduction: Tuberculosis is one of the major public health problems. The COVID 19 pandemic has impacted the health system globally and nationally. Faced with this situation, it was deemed necessary to study the continuity of services related to tuberculosis in Senegal during the COVID 19 pandemic period between March 2020 and February 2021. Methodology: A cross-sectional study for analytical purposes was conducted between March 2020 and February 2021 The study population was represented by all tuberculosis patients seen in consultation between March 2020 and February 2021 and who reside in Senegal. A multistage survey was carried out at the level of each district. Univariate and multivariate analyzes were performed using Epi Info 3.3.2 and R 3.4.4 software. Results: The average age of respondents was 41.43 years with extremes 13 and 81 years. Possession of a television was significantly associated with the impact of COVID 19 on the continuity of tuberculosis services. Patients sensitized before Senegal recorded its first case (ORaj 0.09 [0.02-0.43]) were less likely to continue their health care compared to those who received it after the first case. The request for follow-up consultation service was significantly associated with the impact of COVID 19 on the continuity of services related to tuberculosis. Patients who were in the attack phase (ORaj 107.69 [5.94-1951.97]) and maintenance phase (ORaj 50.06 [7.32-342.07]) were more likely to continue their health care compared to those who did not know what phase they were in. Conclusions: The Results of this work suggest to the health authorities to reorganize the health system and to adopt a policy based on the community approach and to the populations to overcome the "fear of COVID 19".
