Zoonotic Diseases Statistics: Zoonotic diseases, also known as zoonoses, are infectious diseases that can be transmitted between animals and humans.
These diseases are caused by bacteria, viruses, parasites, fungi, or prions and can affect a wide range of species, including wildlife, domestic animals, and humans.
Zoonotic diseases have been a part of human history for centuries, with notable examples like the bubonic plague, but they continue to pose significant threats to public health today.

FAQs
According to the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO), about 60% of all infectious diseases in humans are zoonotic. In the case of emerging infectious diseases, that percentage is even higher, at around 75%.
Low- and middle-income countries are often more severely affected due to lack of sanitation, close living quarters between humans and animals, and limited healthcare infrastructure. However, zoonotic diseases can and do occur everywhere, including high-income countries. For example, Lyme disease is prevalent in the United States and some parts of Europe.
Common examples include rabies, Lyme disease, West Nile virus, Salmonella, and E. coli infections, among many others.
The economic impact can be enormous, affecting not just healthcare systems but also industries like agriculture, tourism, and trade. For instance, the 2003 SARS outbreak is estimated to have cost the global economy around $30 to $50 billion.
