The Los Angeles County Department of Public Health (Public Health) is investigating two human infections with Baylisascaris procyonis, commonly known as raccoon roundworm. Both individuals are currently hospitalized and receiving treatment. Raccoon roundworm is a parasitic roundworm that can infect humans through contact with contaminated soil or water, or by ingesting food or water contaminated with raccoon feces. The human infections were first reported to Public Health on July 28, 2023. The two individuals who tested positive for raccoon roundworm live in different parts of Los Angeles County and have no known connection to each other. "These cases are a reminder that raccoon roundworm is a potential threat to public health in Los Angeles County," said Muntu Davis, MD, MPH, Los Angeles County health officer. "To protect yourself and your family from infection, it is important to take precautions when coming into contact with raccoons and their feces." Symptoms of raccoon roundworm infection can include: - Abdominal pain - Diarrhea - Vomiting - Nausea - Fever - Fatigue - Weight loss In severe cases, raccoon roundworm infection can lead to liver damage, blindness, and even death. Treatment for raccoon roundworm infection typically involves antiparasitic medication. Public Health is working with the California Department of Public Health and the Centers for Disease Control and Prevention (CDC) to investigate the source of the infection. Public Health is also conducting environmental sampling to identify areas where raccoons may be shedding the parasite.
