A contagious illness called zoonosis can transmit between species, from animals to people or the other way around. Zoonotic pathogens can spread to people by direct contact, food, drink, or the environment. They can also be bacterial, viral, parasitic, or involve other unconventional agents, according to the World Health Organisation. Due to our strong contact with animals in agriculture, as companions, and in the natural environment, they constitute a significant public health issue globally.
Ticks and mosquito bites are two ways that zoonotic infections can spread. Zoonoses make up a significant portion of both newly discovered infectious diseases and many already known ones. Some illnesses, like HIV, start as zoonotic strains before evolving into human-only varieties. Salmonellosis and the Ebola virus illness are two examples of zoonoses that can repeatedly cause disease outbreaks. The World Health Organisation stated that still other viruses, including the new coronavirus that causes COVID-19, have the potential to spread globally and produce pandemics. The first vaccine against the diseases is commemorated on World Zoonoses Day 2023, and people are asked to raise their level of awareness of the illnesses.
