Health officials in Kalamazoo are trying to ease parents’ concerns over a recent case of tuberculosis. A high school student tested positive for the bacterial infection last week.

“It sounds scary, but it’s not that scary,” said Linda Vail, director of the Kalamazoo County Health Department.

A Detroit health care worker may have inadvertently exposed 560 people to tuberculosis.

TB is a highly contagious but treatable disease that often infects the lungs.

The Michigan Department of Community Health says the infected worker came into contact with 560 patients who had dental work performed between August and December of 2013 at four Detroit hospitals: Detroit Medical Center, Henry Ford, St. John's, and University of Detroit Mercy Dentistry School.

The situation came to light after the worker developed symptoms and got tested.

Michigan cows are making national headlines. Last week, NPR’s Morning Edition covered a story by Dan Charles on the cattle tracking program in Michigan.

The state of Michigan requires cattle to have electronic ear tags. In fact, it is the only state that requires the tags.

This mattered little to the general public until now. Some farmers are looking at how the tags could help consumers learn more about where meat is from and how it was raised.

Michigan Radio’s Mary Jo Wagner first reported on the tracking system back in 2001. Originally, Michigan started the electronic tracking system in order to monitor cattle for tuberculosis, mad cow disease, and foot-and-mouth disease.

Now, the local food movement and recent exposés on cruelty in the meat industry have given the tags a new use.

Health officials have confirmed a case of  tuberculosis at a high school in suburban Detroit.

WXYZ-TV reports that a student at Northville High School was diagnosed with an active case of the disease and local health officials are working to determine the extent of possible exposure.

From WXYZ:

Parents were notified Monday by a letter from Principal Robert E. Watson, “The protocol followed by the Health Department is to identify other individuals who may be at higher risk of exposure to Tuberculosis during the infectious time period… and to provide an opportunity for testing the identified individuals. ” The infectious time period in this case was January 2012 through April 2012.

Active TB, unlike the latent form of the disease, causes symptoms, is transmittable, and can be fatal if untreated.

According to the Centers for Disease Control, TB bacteria are primarily spread through the air from person to person (e.g. through coughing or sneezing and inhaling bacteria) but not through physical contact like shaking hands.

Data from the CDC show Michigan as having a relatively low incidence rate of TB - 184 cases in 2010 (or 1.9 per 100,000 people). That compares to 11,182 cases nationwide (or 3.6 per 100,00o).

U.S. rates, which have declined steadily for the past 20 years, are dwarfed by the roughly 9 million global cases  in 2010 estimated by the World Health Organization.
