The COVID-19 pandemic has significantly disrupted the global tuberculosis (TB) control efforts. The mobilisation of healthcare resources and personnel to combat the pandemic, and the nationwide lockdown measures resulted in an accumulation of large number of undiagnosed TB cases. Exacerbating the situation, recent meta-analyses showed COVID-19 induced diabetes (DM) is on the rise. DM is an established risk factor for TB disease and worsen outcomes. Patients with concurrent DM and TB had more lung cavitary lesions, and are more likely to fail TB treatment and suffering disease relapse. This may pose a significant challenge to TB control in low- and middle-income countries where high TB burden are found. There is a need to step up the efforts to end the TB epidemic, which include increased screening for DM among TB patients, optimise glycaemic control among TB-DM patients and intensify TB-DM research to improve TB-DM patient treatment outcome.
