Zoonotic disease specialists investigate pathogens shared between humans and animals, assess transmission risks, and develop mitigation strategies. They work across wildlife health, livestock systems, public health agencies, and environmental organisations. Their responsibilities include surveillance of emerging diseases, analysing ecological drivers, coordinating One Health initiatives, and responding to outbreaks. With climate change, habitat shifts, and global mobility, zoonotic threats are rising, making this role increasingly important for global health security. Strong interdisciplinary skills and ecological awareness are essential.
