Governor Green has declared January 2023 as Hawai’i One Health Month! #OneHealth represents the intersection of human health, animal health, and environmental health, and helps us address complex health problems in Hawaii and beyond. See the proclamation here.
Awareness of the One Health approach helps to inform our decision-making, particularly for policy makers and leaders seeking to comprehensively address current issues such as climate change and emerging infectious diseases like COVID-19 or avian influenza. Thinking about how human health is inextricably related to animal health and environmental health also informs our individual everyday decisions: our food choices, the products we buy, appropriate use of antibiotics or other medications, how we care for the native species and habitats we live near, etc.
SARS-CoV-2, the virus that causes COVID-19, is a recent example of a zoonotic disease that can pass from humans to animals and vice versa, causing illness and death in multiple species. The more humans encroach on wild habitats and interact with non-domesticated animal species, the more opportunities there are for viruses or other infectious organisms to spread and mutate into forms that can cause global pandemics. But zoonotic disease spread is just one example of the interplay between human, animal, and environmental health. Other important examples include how the use of pesticides has decimated bee populations, which in turn decreased pollination, crop yields, and human food supply; or how medication prescribed in human and veterinary medicine can pass through their patients to enter the environment and cause developmental deformities in wildlife and drug-resistant infections; or how lead shot used in hunting has resulted in lead toxicity in scavenging animals such as birds of prey and humans alike.
One Health concepts have been a part of many veterinary curricula and may seem obvious to veterinarians, but many of our colleagues in other health and science disciplines were not trained to think outside of their specific fields. Keep the One Health perspective in mind, and encourage others to do the same!
