Georgia is Among Top Ten States in the Nation for Heartworm Infection

American Heartworm Society urges Peach State pet owners to stay vigilant

WILMINGTON, Del.--()--The good news for Georgia’s pets: the Peach State has improved its position in the battle against one of the deadliest diseases threatening dogs and cats. The bad news: according to the American Heartworm Society (AHS), which conducts a nationwide incidence survey every three years, Georgia remains in the top ten states for heartworm disease diagnosis.

The latest AHS survey is based on testing data from the 2013 calendar year. More than 4,500 veterinary practices and shelters in the nation participated, contributing data from an estimated 3.5 million patients. Results of the survey are being released to help pet owners better understand the threat of heartworm disease, both nationwide and in their area.

The state-by-state breakout of the findings shows that Georgia came in ninth place behind Alabama, Louisiana, Mississippi, Texas, Arkansas, South Carolina, North Carolina and Tennessee, with Oklahoma in tenth place. Three years ago, Georgia was in fifth place.

“We commend Georgia veterinarians and pet owners for taking a step in the right direction,” states AHS president Stephen Jones, DVM. “At the same time, these numbers indicate that Georgia pet owners need to be vigilant about heartworm protection.”

The American Heartworm Society bases their rankings on the average number of heartworm-positive dogs per clinic. During the 2013 calendar year, Georgia veterinary practices reported an average of 23 heartworm-positive dogs per clinic; this compares to 37 in 2010.

Heartworm disease affects pets nationwide
Heartworm disease has been diagnosed in all 50 states, and states in the southeast quadrant of the U.S. historically have led the nation in heartworm incidence. Heartworm disease is spread via mosquitoes, and warm-weather states with high mosquito populations face significant disease risk. High local populations of infected dogs and wildlife (coyotes and foxes carry heartworm) also increase the risk of heartworm to unprotected pets.

Treatment for heartworm infection in dogs is available, but is costly and requires strict supervision by both veterinarians and owners, as well as several months of cage confinement. Dr. Jones notes that while dogs with heartworm disease can be successfully treated, the infection can cause permanent damage to a pet’s organs and circulatory system. Meanwhile, there is no approved treatment medication for heartworm disease in cats.

The annual cost of prevention typically runs less than ten percent of the cost of treatment. In addition, a number of heartworm preventives also protect pets against intestinal parasites and fleas as well as heartworms.

“Heartworm disease is a deadly—but preventable—disease,” Dr. Jones concludes. “That’s why the American Heartworm Society recommends that pets be tested for heartworm each year and that dogs and cats be put on preventive medicine for heartworm year-round.”
