Why Don't Humans Get Heartworm? (Spoiler: We Do)

Heartworm disease is a serious condition caused by parasitic worms transmitted by mosquitoes, primarily affecting dogs. In dogs, the worms can cause severe health issues, including heart failure. Preventative medications are crucial for reducing infection risk. Humans can also be infected, but cases are rare and less severe due to the human immune system's ability to combat the worms. The bacteria Wolbachia, living inside the worms, play a role in the infection process by manipulating the host's immune response. Understanding the disease's impact on dogs and the importance of prevention is vital for pet owners.
