An outbreak of infections in Wisconsin caused by Elizabethkingia  anophelis bacteria may be associated with 18 recent deaths in the state. The exact cause of the outbreak is currently unknown, and was first recognized by the Division of Public Health in Wisconsin in late December, 2015.

The Centers for Disease Control and Prevention (CDC) has sent 5 employees to investigate the outbreak, who will join their Wisconsin Department of Health Services (DHS) and Division of Public Health (DPH) counterparts who are already working to pinpoint the source of the outbreak.
