Zoonoses are infectious diseases that have been transmitted between animals and humans or in an advanced stage from humans to humans. It can also be transmitted from humans to animals, when this happens it is called reverse zoonosis. Emerging zoonoses are newly recognized or newly evolved infectious diseases, while re-emerging zoonoses have occurred previously but have more recently shown an increase in incidence or expansion into a new geographic, host, or vector range . The concept of “emerging zoonotic diseases” developed as health scientists documented and attempted to explain the apparent sharp increase in the number of new and important infectious diseases over the past two decades (Bengis et al. , 2004). Zoonoses are widely transmitted from wildlife to domestic animals and livestock and can be transmitted in different ways: 1) Viral, some of the best known are: HIV, Ebola virus, Hantavirus, rabies, Hendra, Nipah virus, Menangle virus. West Nile virus infection, severe acute respiratory syndrome, avian influenza and Monkeypoxvirus infection. 2) Bacterial: Lyme borreliosis, Ehrlichiosis, Bovine tuberculosis (Mycobacterium bovis), Brucella spp., Tularemia, Plague and Leptospirosis. 3) Parasite: Cysticercosis/Teniasis, Rematodosis, Echinococcosis/Hydatidosis, Toxoplasmosis and Trichinellosis. 4) Fungi: dermatophytosis and sporotrichosis. Zoonosis poses an unknown threat to humanity since ancient times, when sanitation was not a concern and bushmeat consumption was widespread. Zoonoses began to become a real social problem with the beginning of agriculture. Because people lived in small groups and rarely had contact with different tribes. Everything changed when the disease appeared in the middle of paper (Leeflang et al., 2008). Zoonotic infectious diseases have always been a threat to the world's population, both animal and human. When it is not fatal, it causes serious injuries generally costing society large sums of money. While some countries manage zoonotic diseases quite well, others (especially developing countries) struggle with them. Although no nation is 100% safe from emerging and re-emerging zoonotic diseases, with all the different forms existing acting differently in different places. Zoonotic diseases have always affected humanity, but thanks to observations, research and studies on new emerging and re-emerging pathogens, the situation has improved significantly over the past 20 years. The best way to prevent it is good hygiene habits, early diagnosis through technical advancements in diagnosis and also cooperation between countries for a better global solution..
