Pulmonary tuberculosis and nCovid 19 share many common risk factors. nCovid19 may increase the risk to develop pulmonary tuberculosis. Pulmonary tuberculosis may precede, co-exist or follow nCovid19. Careful evaluation of chest radiography is useful to differentiate tuberculosis from nCovid19 bronchopneumonia. Symptoms of tuberculosis may be mistaken for long covid. A normal chest x ray in the absence of sputum production may help to rule out tuberculosis in such cases. All patients with nCovid19 bronchopneumonia should undergo a careful chest x ray evaluation for any lesions suggestive of tuberculosis. All patients with chest radiological abnormality should undergo sputum examination to rule tuberculosis as atypical radiological manifestations may be more common in patients with nCovid19. Symptoms, signs, clinical features and chest radiographic features of Pulmonary tuberculosis and nCovid19 bronchopneumonia may overlap in some cases. Correlation of chest radiographic findings with epidemiologic history, clinical presentation, and RT-PCR test results or in later stages antibody titres will help in confirming or excluding the diagnosis in suspected cases of nCovid19. In pulmonary tuberculosis definitive diagnosis should be established by bacteriological confirmation. Molecular diagnostic tools should be used to confirm or exclude tuberculosis in suspect cases as the results are rapid, accurate and reliable.
