Every three years, the American Heartworm Society (AHS) gathers data on heartworm testing to understand the impact heartworm is having nationwide, as well as in specific regions. Testing data from thousands of veterinary practices and shelters is used to create a detailed map showing the average number of heartworm-positive cases per clinic.

The new map, which reflects data from the 2013 calendar year, shows that heartworm is widespread in many areas of the country. Download it today and check out the incidence of heartworm in your practice area. You can also compare the 2013 map to past maps from 2001-2010.

A Picture is Worth a Thousand Words About Heartworm.

A clear understanding of the heartworm life cycle is vital in getting clients on board with year-round prevention, and pet owners who understand the rationale for your heartworm prevention and treatment recommendations are more likely to comply. Understanding, however, may require more than a verbal explanation of how heartworms are transmitted and develop.

It's spring, and your schedule is booked with patients getting their annual exams, heartworm tests and heartworm prescription renewals.

And because April is also Heartworm Awareness Month, it's a prime opportunity to promote the importance of year-round protection for both dogs and cats. A new series of posters from the American Heartworm Society (AHS) uses compelling images and messages to remind pet owners that providing heartworm prevention is one of the most important—and most loving—things they can do for their pets.

Adulticide supplies are available for heartworm-positive dogs.

Reports about supplies of melarsomine have been in the news recently, which may be raising questions about whether supplies of the product are adequate. The news reports were triggered by a bulletin from the U.S. Food and Drug Administration (FDA) that announced their decision to approve a supply of product from Europe for use in the U.S. This was done to help ensure product availability until a supply of U.S.-made product is available.

An overview of the highlights from the revised American Heartworm Society's canine and feline guidelines by Stephen Jones, DVM.

"As a veterinarian practicing in the Lowcountry of South Carolina, I deal with heartworm-positive patients nearly every day. Consequently, I've taken a special interest in the long-term effects of heartworm disease. Over the past six years, I have studied necropsy results from dozens of canine and feline patients that either had an active heartworm infection at the time of death or had been treated for heartworm disease during their lifetime..."

An increased emphasis on the importance of heartworm prevention, as well as new scientific information about heartworm resistance, testing and treatment, have prompted the American Heartworm Society (AHS) to revise its guidelines for dogs and cats. The updates to the guidelines were announced during the AHS’s half-day symposium at the North American Veterinary Conference earlier this week.

In certain areas of the United States, most notably the Mississippi Delta region, an inordinate number of dogs have become infected with heartworms while reportedly taking preventive medication. Practitioners diagnosing these unexpected heartworm infections have begun to question the effectiveness of macrocyclic lactones.
