Tuberculosis is associated with a 2.1-fold increased risk of a severe COVID-19 disease, the health ministry said, recommending that all newly-diagnosed tuberculosis patients or those currently on treatment should be tested for COVID-19 and vice versa. The prevalence of tuberculosis among COVID-19 patients has been found to be 0.37 to 4.47 per cent in different studies, the ministry said and highlighted that there has been an overall decline in tuberculosis notification by 26 per cent during January to June, as compared to the previous year, due to the coronavirus pandemic.

In its “Guidance note on Bi-directional TB-COVID screening and screening of TB among ILI/SARI cases” issued on Wednesday, the ministry said studies have shown that a history of active as well as latent tuberculosis is an important risk factor for the SARS-CoV-2 infection.

“This not only results in increased susceptibility, but also rapid and severe symptom development and disease progression with poor outcomes. Tuberculosis is associated with a 2.1-fold increased risk of severe COVID-19 disease,” the document said.
