Transmission & Treatment

Virtually every horse will be exposed to equine influenza at some time. The virus is highly contagious and is passed from horse to horse via respiratory secretions. When infected horses cough, share feeders, waterers, tack and equipment, or come into physical contact with healthy horses, the infection spreads rapidly.

The best treatment for equine influenza is complete rest while the illness runs its course. One week of rest for each day of fever is recommended; this typically equates to 30 to 60 days out of training and competition. In addition, horses should be isolated and monitored closely during this time for signs of secondary bacterial infections.
