Hookworms are a common, more serious intestinal parasite of dogs, cats, and other animals. Hookworms are transmitted when the eggs are passed out with the stool and then an animal eats the eggs or larvae, penetration of the skin or footpads by larvae, or spread of the larvae from the mother while the fetus is still in the uterus. Adult hookworms attach to the lining of the small intestines and such the animal’s blood. This can cause anemia (low red blood cells), weight loss, diarrhea, and tarry or bloody stool. In young or weak animals hookworms can cause sudden collapse and death. An animal is diagnosed with hookworms by identifying the eggs during microscopic examination of the stool. Hookworm infections are treated with the appropriate medication. Monthly use of some heartworm preventions helps treat and control hookworm infections.
Public Health Concern
As in animals, hookworm larvae can penetrate the human skin and cause a skin disorder known as “coetaneous larval migrans”. The condition is uncommon, however f a red rash develops on the skin please consult a physician.
