History of Heartworm Awareness Month
The history of heartworm awareness traces back to 1856 when heartworm infections were first discovered in dogs. It wasn’t until 1921 that similar infections were identified in cats. The growing concern over heartworm disease led to the founding of the American Heartworm Society during the Heartworm Symposium in 1974, marking a significant step in raising awareness. By August 2020, the disease had become increasingly prevalent, prompting industry leaders to emphasize the importance of a national awareness month, which continues to highlight the risks and prevention of heartworm in pets.
Heartworm is caused by the parasitic worm Dirofilaria immitis, which is transmitted through the bite of an infected mosquito. Once inside a pet’s body, these worms migrate to the heart, lungs, and blood vessels, where they can live for years, causing significant damage to the animal’s cardiovascular and respiratory systems. It’s important to note that heartworm disease is not contagious between pets; it can only be spread through mosquito bites, which makes preventive care critical. The signs of heartworm infection vary between species, with dogs often exhibiting a persistent cough, fatigue, and weight loss, while cats may show symptoms like coughing, vomiting, and decreased appetite.
Given the long-term impact heartworm can have on an animal’s health and quality of life, it is imperative for pet owners to remain vigilant. Following the recommendations of the American Heartworm Society, regular screenings and year-round heartworm preventative medication are essential steps in protecting pets from this insidious disease. National Heartworm Awareness Month serves as a crucial reminder for pet owners to take proactive measures in safeguarding their beloved companions from the dangers of heartworm disease.
