 The study found that 14.7% of the healthcare workers at Ayatollah Rahani Hospital Babel had latent tuberculosis. The majority of those infected, 71.7%, were female, and the average age was 32.7 years old. Additionally, the incidence of latent tuberculosis was higher among technicians, 8.8%, and nurses, 6.6%, compared to other occupations such as services, 2.5%, or administration, 0%. Furthermore, 17 out of the 18 individuals who tested positive for latent tuberculosis had a history of exposure to a patient with active tuberculosis. Based on these findings, it can be concluded that the incidence of latent tuberculosis in this hospital is relatively high, and that the most important risk factor is long-term work experience. Therefore, healthcare personnel training and infection control programs should be implemented to reduce the risk of transmission.
