We read with interest the article by Nikolayevskyy et al.  reporting significant disruption to clinical tuberculosis (TB) services during the coronavirus disease 2019 (COVID-19) pandemic. Reductions in TB diagnoses during the pandemic have been reported worldwide [1–4]. These findings have been attributed to a reduction in admissions due to lockdown, the spillover effect of public health measures against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on other respiratory infectious diseases, and diversion of resources towards the COVID-19 response [1–4]. During the pandemic, healthcare systems grappling with a surge in COVID-19 cases encountered sustained disruptions to TB services , potentially delaying diagnosis. Delayed detection of TB amongst hospitalised patients increases risk of nosocomial transmission . In centres that were not overwhelmed, however, increased vigilance for respiratory symptoms may potentially translate into increased detection of active pulmonary tuberculosis (pTB) amongst hospitalised patients.
This study shows an increase in the rate of pulmonary tuberculosis (TB) detected amongst hospitalisations during the COVID-19 pandemic, while detection of extrapulmonary TB remained unchanged; due to improved surveillance and chest imaging utilisation https://bit.ly/3fhVaMG
