The other premises was quarantined on 2/13/2020 and has one clinical horse (confirmed). All horses are alive and being treated by a veterinarian.

The highly contagious upper respiratory disease of equids, known as Strangles, is caused by the gram-positive β-hemolytic bacterium Streptococcus equi ssp. equi.

The incubation period typically ranges between two and six days but may last up to 14 days.

Classic symptoms may include fever (103 degrees F or higher), mucopurulent nasal discharge, lymphadenopathy (+/- abscessation), general malaise, pharyngitis, dysphagia, upper airway stridor and respiratory distress.

Clinical signs are often age-related, with older horses exhibiting milder symptoms of shorter duration.
