Department of Health Services Investigating an Outbreak in Southern Wisconsin

Wisconsin Department of Health Services is investigating the death of 18 senior citizens who have died in southern Wisconsin after having a bacteria infecting their bloodstreams.

 “The Elizabethkingia infection has been detected in 44 patients located in southeastern and southern Wisconsin. The majority of patients are over the age of 65 years, and all have serious underlying health conditions,” said State Health Officer Karen McKeown. “As soon as we were notified of the potential outbreak, Wisconsin’s disease detectives began working immediately to identify the source.” 

Illness associated with Elizabethkingia typically affects people with compromised immune systems or serious underlying health conditions, and can lead to death.

While 18 patients who tested positive for the Elizabethkingiainfection in this outbreak have died, it has not been determined if the cause is the bacterial infection, or the patients’ other serious health conditions, or both.

DPH was first notified of six potential cases between December 29, 2015 and January 4, 2016 and set up statewide surveillance on January 5, 2016.  DPH then alerted health care providers, infection preventionists, and laboratories statewide of the presence of the Elizabethkingia bacteria, and provided information as well as treatment guidance, which has led to a rapid identification of cases, and appropriate treatment.

“Determining the source of the bacteria affecting patients in Wisconsin is a complex process,” McKeown added. “While we recognize there will be many questions we cannot yet answer, we feel it is important to share the limited information we have about the presence of the bacteria, as we continue our work to determine the source.”
