Francois Meslin explains why animal illnesses are serious threats to human wellbeing:
[E]ffective control and prevention often needs to be targeted at the animal reservoir rather than the people, while the budgets for such diseases (if there is a budget at all) rests with the human health services. Human health protection thus must include or even depend on the veterinary sector, which is itself relatively underfunded (budgets for human health promotion usually end up in Ministries of Health). Thus, these problems often fall between the cracks of responsibility.
