Zoonotic Diseases | One Health | CDC# A zoonosis is an infectious disease that has jumped from a non-human animal to humans. 

# Zoonotic pathogens may be bacterial, viral or parasitic, or may involve unconventional agents and can spread to humans through direct contact or through food, water or the environment. 

# Some diseases, such as HIV, begin as a zoonosis but later mutate into human-only strains. 

# Other zoonoses can cause recurring disease outbreaks, such as Ebola virus disease and salmonellosis. 

# Still others, such as the novel coronavirus that causes COVID-19, have the potential to cause global pandemics. 

# Antimicrobial resistance is a complicating factor in the control and prevention of zoonoses

# Zoonotic pathogens can spread to humans through any contact point with domestic, agricultural or wild animals. 

# Markets selling the meat or by-products of wild animals are particularly high risk due to the large number of new or undocumented pathogens known to exist in some wild animal populations.

# Agricultural workers in areas with a high use of antibiotics for farm animals may be at increased risk of pathogens resistant to current antimicrobial drugs.
