Officials investigate active TB cluster in N.D.

Officials with the North Dakota Department of Health, Altru Health System and Grand Forks Public Health Department are looking into a cluster of active tuberculosis cases in Grand Forks County.

The state health department recently confirmed three active TB cases in the county in three men - one in his 20s and the two others in their 40s, KSJBam.com reports.

The officials are using contact investigations to determine if anyone was exposed to the active cases. People considered to be at risk will be contacted and given information about testing procedures.

Groups that could be contacted include roommates, friends, coworkers and family members.

Each of the three cases indicated they are staying with family or friends and have no permanent address. None of them indicated that they have stayed in a shelter, KSJBam.com reports.

The three cases may be connected to cases that were previously confirmed in the area.

TB is a disease that can spread through the air when someone with active TB disease coughs or sneezes into the air. TB exposure is typically the result of prolonged or frequent exposure.

Individuals at the most risk of complications from TB include people with compromised immune systems.
