TB positive cases go up in ongoing COVID-19 pandemic.
•
More female patients got infected with TB in 2020 (January–October 2020).
•
The information on COVID-TB co-infection is limited.
•
Thorough understanding of COVID-TB co-infection is crucial in managing COVID-19.
Abstract
The whole world is wrestling against SARS-CoV-2 infection (COVID-19). COVID-19-TB co-infection is also reported but there are limited number of studies which analyze the impact of COVID-19 pandemic in TB diagnosis and management. In this retrospective study, we observed that the TB diagnosis was reduced in pandemic time. Before COVID-19 pandemic (March–December 2019), there were 644 TB tests out of which 127 were TB positive. In ongoing COVID-19 pandemic (January–October 2020), 484 TB tests were performed and 146 patients were TB positive. Male accounted for 64%/57% of TB cases in 2019/2020 whereas female patients were 35%/42% in 2019/2020. Increase in female TB positive cases was a noticeable feature. The newly diagnosed with TB cases in 2019/2020 were 112/130 respectively. Though, we have seen only 7 COVID-TB co-infection cases, we could not establish the causal relationship in COVID-TB co-infection. The increase in the number of TB positive cases during COVID-19 pandemic clearly showed how adversely COVID-19 has affected TB diagnosis and management. Anticipating the increase in TB cases in future, we emphasize the need to ensure continuous TB testing and treatment despite the pandemic burden. Further study on the COVID-TB co-infection in high TB-burden countries like India, is required to enable analyses of interactions, risk factors in COVID-19-TB co-infection.
