Officials: Patient at Royal Oak Beaumont diagnosed with Legionnaires'

Detroit News staff and wire reports

A patient treated at Beaumont Hospital in Royal Oak has been diagnosed with Legionnaires’ disease, representatives announced Friday.

Beaumont Health, which has eight hospitals in its system, did not release further details about the patient but said officials were following Centers for Disease Control and Prevention guidelines and "taking appropriate action, such as providing bottled water and continuing the water sampling tests we routinely conduct."

The Beaumont hospital system has "a robust water safety plan," officials said Friday.

According to the CDC, Legionnaires’ is a serious type of pneumonia caused by bacteria that can sicken people when they breathe in mist or accidentally swallow water containing it.

"The safety of our patients, families and staff is our top priority," Beaumont officials said Friday. "We have a robust water safety plan that includes regular monitoring and testing. In our ongoing testing, temperature, pH and chlorine levels have all been within appropriate ranges."

Legionnaires' can thrive in buildings with large water systems.

Symptoms include shortness of breath, muscle aches, headache and fever. Symptoms usually appear two to 10 days after exposure.

About 20 outbreaks are reported each year, including recent ones at an Atlanta hotel and a hospital near Chicago. An outbreak killed 12 people and sickened dozens of others in Genesee County in 2014-15.

In a recent report, experts said annual cases of Legionnaires' jumped more than five-fold from 2000 to 2017, and that as many as 70,000 Americans get the disease every year.
