Introduction Tuberculosis (TB) is the 13th leading cause of death and the second leading infectious disease, following Coronavirus disease 2019 (COVID-19). Co-infection with COVID-19 and tuberculosis has been documented in various parts of the world, and this condition is of interest to many medical professionals.

She was initially examined by a gastroenterologist, and pulmonary illness was suspected after further evaluation by an expert ear, nose, and throat (ENT). Computed tomography (CT) of the chest revealed postprimary tuberculosis (PTB). The woman was given antituberculous medications, tranexamic acid, glucocorticoids, low molecular weight heparin (LMWH) in prophylactic doses after the bleeding stopped, and vitamins. Conclusion Co-infection with COVID-19 and tuberculosis is a severe illness, especially in older people with comorbidities, and can lead to disease progression and even death.
