West Nile Virus Antibody: Take Control of the West Nile Virus
GREENSBORO, NC (Sept. 15, 2004) –

When it comes to caring for horses that have the West Nile Virus, veterinarians’ options have been limited. However, a product is available to help against this threatening mosquito-borne virus.

The West Nile Virus Antibody, manufactured by Novartis Animal Health, is available under a conditional license by the USDA for use in yearling or older horses as an aid in the control of disease caused by the West Nile Virus.

According to Richard Harland, DVM, director of research and development for Novartis
Animal Health, the product potentially can save the lives of horses who have contracted
the virus and are exhibiting clinical signs of the disease.

West Nile Virus Antibody is a prescription product, administered intravenously by a licensed veterinarian. It increases the antibody level in the circulatory system, thus enhancing an animal’s ability to neutralize virus present in the blood. Cornell University conducted a neutralizing index study that demonstrated the ability of the West Nile Virus Antibody to neutralize the West Nile Virus. In addition, field safety trials demonstrated West Nile Virus Antibody is safe when used according to label directions.

“Veterinarians can prescribe the product with confidence, knowing it is a safe choice that targets the West Nile Virus,” Harland says. Harland advises horse owners to keep a close eye on horses and watch for clinical signs of the West Nile Virus.

“If an owner observes any clinical signs – such as ataxia, depression, weakness of limbs, partial paralysis and muscle twitching – they should contact their veterinarian immediately,” Harland explains. “An early diagnosis and prompt veterinary care will improve the chances of recovery.”
