EqStim Immunostimulant

 EqStim is used in the treatment of Equine Respiratory Disease Complex. Respiratory disease is most commonly caused by Equine Herpes Virus (EVH-1 and EVH-4). These viruses cause an upper respiratory tract infection in susceptible horses,
causing disease that is very similar to a head cold or the flu in people.Horses usually breathe in sneezed droplets from another infected horse; this is one way your horse can become infected. They can also become infected through contact with contaminated dust or feed. Once infected, the virus has an incubation period of 3-4 days. Infected horses usually carry the virus for around 7 days, though it can persist in nasal secretions for up to 20 days.

Common causes of ERDC include: 

Equine Herpes Virus    
Equine Influenza Virus        
Equine Arteritis Virus      
Equine Adenovirus
