Strangles cases confirmed in Washington and Wisconsin horses

Recent reports have confirmed cases of strangles, an infection caused by Streptococcus equi subspecies equi, in horses located in Washington and Wisconsin.

In Whatcom County, Washington, a horse recently transported from Texas tested positive for the infection. The animal is currently recovering under veterinary care, while two other horses exposed at the private farm have been placed under quarantine.

In Dane County, Wisconsin, a 13-year-old Quarter Horse gelding at a boarding facility also tested positive. The horse exhibited symptoms including fever, cough, and nasal discharge and is currently in recovery.

Strangles is spread through direct contact with other equids or contaminated surfaces. Symptoms can include fever, swollen lymph nodes, nasal discharge, and coughing. While most horses make a full recovery within three to four weeks, the bacteria can be harbored by asymptomatic horses, potentially leading to long-term outbreaks.
