TB and People Experiencing Homelessness
People experiencing homelessness are at an increased risk of becoming infected with TB germs compared to the general population. The increased risk of infection with TB germs is due to several factors, including substance use, HIV infection, and the homeless shelter environment such as crowding and the state of the ventilation system. This combination of factors is favorable for spreading TB. In addition, people experiencing homelessness often lack ready access to the medical care required to make an early diagnosis of TB disease.
Among persons aged 15 years of age or older with TB in 2021, 341 (4.5%) reported experiencing homelessness within the 12 months preceding TB diagnosis. This compares with 290 (4.3%) of TB cases in 2020 among persons aged 15 years of age or older with reported homelessness in the United States.
To address TB among people experiencing homelessness, CDC is:
- Collaborating with other national and public health organizations to improve screening, diagnosis, and treatment for people experiencing homelessness;
- Working to improve TB control activities in partnership with healthcare agencies addressing the needs of people experiencing homelessness.
People experiencing homelessness are an important group at increased risk of TB. To achieve TB elimination, ongoing efforts are needed to address the disproportionate number of TB cases among this population.
