  As the number of confirmed cases of coronavirus disease 2019 (COVID-19) surged after the emergence of the Omicron variant in December 2021, the possibility of reinfection surfaced. Therefore, 16,130,920 cumulative confirmed cases from January 2020 to April, 2022, were investigated for presumptive COVID-19 reinfection. The results revealed that there were 55,906 presumptive reinfection cases, with a reinfection incidence rate of 0.35%. The number of COVID-19 reinfection cases increased by approximately three times from January to April 2022, which is the period after the Omicron variant outbreak, compared with that noted before the Omicron variant outbreak. The occurrence of presumptive COVID-19 reinfection cases shows an increasing trend because the number of confirmed cases surged after to the Omicron variant outbreak and individuals with a positive rapid antigen test result were also recognized as confirmed cases.

  To improve the success rate of tuberculosis (TB) treatment by TB patients treated by the private sector, the Korean government has been promoting a national public-private mix (PPM) TB control project with the Korean Academy of Tuberculosis and Respiratory Diseases since 2011. This study analyzed the indicators for TB management reported by medical institutions participating in the 2020 PPM TB control project (164 hospital) and compared them with analysis data for the previous three years (2017-2019). The final treatment results were confirmed through five-quarter observation by dividing the reported date by quarters.
  In 2020 the number of reported patients of the PPM project, the ‘sputum smear test rate’ and ‘sputum culture test rate’ were 95.2% and 94.8%, respectively. These numbers, have continued to increase since 2017. However, the ‘drug sensitivity test (DST) implementation rate’ was 93.5%, which was similar to the previous years, and the ‘rapid DST implementation rate’, which was added in 2020, was 66.5%.
  In 2020, the ‘compliance rate of the initial standard treatment regimen’ was 93.4%. However, the ‘treatment completion among smear positive patients’ decreased from 86.8% in 2018 before the COVID-19 pandemic to 84.7% and 84.0% in 2019 and 2020, respectively. In 2020, the ‘Treatment completion within 12 months’ was 76.2%, the ‘mortality rate’ was 13.3% and ‘still on treatment’ was 8.5%. The number of ‘treatment stopped’ was 2.0% and ‘treatment failed’ was 0.03%. The ‘contact investigation rate’ and the ‘initiated latent tuberculosis infection (LTBI) treatment rate’ have steadily increased in both adults and children.
  In 2020, the COVID-19 pandemic adversely affected the medical system. However, the TB management indicators were maintained or improved in comparison to the previous year, since the PPM project, which began in 2011, played a crucial role. To end TB, the PPM project is essential, and patient-centered case management is important.
