Abstract
|
|
|
Tuberculosis (TB) is caused by Mycobacterium tuberculosis and is transmitted through air. Transmission depends on
proximity and exposure time. In October 2021, this facility reported by two residents with TB, and 188 people, such as staff
who contacted patients with TB and other residents were tested for TB. Two additional patients with TB were identified along with 59 cases of latent tuberculosis infection (LTBI). Generally, proximity and exposure time increases the rate of infection in vulnerable groups such as the homeless population. People in this population share their living spaces and have frequent contact with each other. This circumstance resulted in high rates of TB infection or LTBI. This study investigated TB in homeless shelters. We attempted to determine a method for early detection and additional transmission in contact with patients with TB. We also provide a method for the detection and treatment of LTBI. In conclusion, we aimed to prevent and manage TB in this vulnerable group through education. Thus, residents and workers in shelters should be educated on TB information in the community
