What is Zoonosis?

Zoonosis is an infectious disease that transfers from non-human animals to humans. These pathogens may be viral, bacterial or parasitic. They spread to humans through direct contact, water, food and environment.


The guidelines issued were in line with the concept of “One Health”. This term was first used in 2003-2004. It was associated with the emergence of SARS and Avian Influenza H5N1. SARS is Severe Acute Respiratory Disease. According to One-Health, the health of human beings is associated with the health of environment and animals.
