Q. I’m a big believer in heartworm prevention, but I find myself repeating my “heartworm 101” lecture over and over to clients. Is it worth it?
by Charles Thomas (Tom) Nelson, DVM
A. In a 2014 American Heartworm Society survey, veterinarians were asked if the incidence of heartworm disease in their area had increased over the past three years, decreased or stayed the same.

Q. Why is melarsomine recommended by the American Heartworm Society (AHS), given the potential for complications during adulticide treatment?
by John McCall, MS, PHD
A. Heartworm disease is considered the most important vector-borne disease of dogs in the U.S. and many other parts of the world. Targeting vectors as part of a preventive approach to controlling mosquito-borne human diseases has been critically important for decades, but has received much less attention in companion animal disease prevention.

Feline heartworm disease (HWD) has a low index of suspicion and is significantly under-diagnosed. Knowing when to test cats for HWD—and whether to test them—is important. The challenge boils down to this: no single test can accurately detect heartworms at all stages in cats. Thoroughly understanding the limitations of antigen and antibody tests is necessary to utilizing these assays with confidence.
MARTHA SMITH-BLACKMORE, DVM
Heartworm disease (HWD), caused by the mosquito-borne nematode Dirofilaria immitis, is endemic in most areas of the United States, including urban areas where most of the U.S. population (about 80%) lives.

The American Heartworm Society (AHS) guidelines for heartworm prevention, diagnosis and treatment are much more than reference documents. They equip veterinarians like me to make life-saving differences in my patients’ lives.
CHRISTOPHER J. REHM, DVM
The American Heartworm Society (AHS) has developed almost 30 pages of guidelines for the prevention, diagnosis and treatment of heartworm disease in dogs and cats.1 But the AHS’ two basic precepts are summed up in just 12 words: test every 12 months and prevent heartworm disease 12 months a year. While this sounds simple, achieving compliance can be challenging.
