It was found that the surveillance system in the Republic of Tajikistan is flexible. It quickly adapted to the conditions of the pandemic. From August 21 to March 27, only for 19 of the 36 observed weeks (53%), all 7 objects provided report on time. Overall, weekly timely reporting was 92% (range 71-100% for 36 weeks). 706 cases were registered, 662 correctly met the definition, which led to a specificity of 94% (662/706). 46 more cases were not reported, which led to sensitivity of 88% (662/(662+46)).Conclusion.
