Delayed diagnosis of pulmonary tuberculosis (TB) in a pregnant patient led to a significant outbreak, infecting 15 individuals across hospital wards. This highlights the critical need for prompt TB detection in healthcare settings.

Area of Science:

  • Infectious Diseases
  • Public Health
  • Epidemiology

Context:

  • A pregnant patient admitted for threatened abortion was later diagnosed with smear-positive pulmonary tuberculosis (TB) with cavity.
  • The diagnosis was delayed, occurring during her second hospital admission in a perinatal ward.

Purpose:

  • To investigate a TB outbreak originating from a delayed diagnosis in a hospital setting.
  • To identify the transmission routes and extent of the TB spread.

Summary:

  • A 22-year-old pregnant woman, initially admitted for threatened abortion, was diagnosed with pulmonary TB two months later during her delivery admission.
  • This led to a subsequent outbreak of 15 new TB cases, including patients on obstetric and perinatal wards, visitors, and family members.
  • RFLP analysis confirmed the transmission of a unique Mycobacterium TB strain, with seven cases linked to the obstetric ward.

Impact:

  • The outbreak underscores the substantial risk of TB transmission in obstetric and perinatal wards.
  • Highlights the critical importance of timely diagnosis and isolation of smear-positive pulmonary TB patients to prevent nosocomial spread.
  • Emphasizes the need for enhanced surveillance and infection control measures in healthcare facilities, particularly for vulnerable populations.
