The Cabell-Huntington Health Department is making contact with more than 100 people as it investigates two confirmed cases of tuberculosis.
The agency issued a health advisory Friday regarding both cases, which were confirmed late last week in the Huntington area.
The department estimates the two infected patients might have exposed 150 people.
While federal privacy laws restrict the agency from releasing the patients' identities and other specifics, officials say they'll be making contact with anyone who had been exposed.
Agency spokeswoman Elizabeth Ayers says the additional tests were precautionary steps and should not cause widespread concern.
Tuberculosis is a bacterial disease that's spread through the air attacks the lungs but can also affect other parts of the body, such as the kidney, spine and brain.
