[[CASE OF TUBERCULOSIS COMPLICATIONS DURING PREGNANCY LEADING TO AN INFECTION OUTBREAK].]

A 31-year-old woman developed a constant cough during the 8th week of pregnancy and was diagnosed with bronchial asthma. She was prescribed prednisolone and inhaled corticosteroids. At 28 weeks of pregnancy, she showed worsening weight loss, fever, night sweats, hoarseness, and coughs. At 31 weeks of pregnancy, a scatter shadow and cavitary lesions were detected on the chest radiograph. Acid- fast bacilli smear test and tuberculosis (TB) polymerase chain reaction tests yielded positive results (G-8), and she was diagnosed with TB. Contact tracing and screening indicated 3 patients with TB onset and 18 patients with latent TB infec- tion attributed to the initial patient, who infected a total of 36 people. In the present case, physicians were reluctant to order a chest radiograph for fear of harming the fetus and did not order sputum or interferon gamma release (IGRA) assay tests either. The diagnosis was delayed by 152 days, which was considered as a factor that caused the outbreak. The diag- nosis of TB in a pregnant patient may be very challenging because symptoms may initially be ascribed to the pregnan- cy, and delayed diagnosis and treatment of military TB can lead to the death of the mother and fetus. Consequently, to ensure early diagnosis and treatment, chest radiography and sputum and IGRA tests are recommended for pregnant women who have TB symptoms or are at high risk for TB.
