These are infectious diseases that is transmitted between species from animals to humans (or from humans to animals).
Zoonoses can be caused by a range of disease pathogens such as viruses, bacteria, fungi and parasites; of 1,415 pathogens known to infect humans, 61% were zoonotic. Some examples of zoonoses.
Every year millions of people get sick because of foodborne zoonoses such as Salmonellosis and Campylobacteriosis which cause fever, diarrhoea, abdominal pain, malaise and nausea. Other bacterial zoonoses are anthrax, brucellosis, infection by verotoxigenic Escherichia coli, leptospirosis, plague, Q fever, shigellosis and tularaemia.
Parasites: Cysticercosis/Taeniasis is caused by a parasite which infects swine and can cause seizures, headache and many other symptoms in humans. In Latin America for example, 100 out of 100 000 inhabitants suffer from this disease (estimation). Other parasitic zoonoses are trematodosis, echinococcosis/hydatidosis, toxoplasmosis and trichinellosis
Rabies: Rabies is a disease of carnivores and bats mainly transmissible to humans by bites. Almost all persons infected by rabid animals will die if not treated. An estimated number of 55 000 persons, mainly children, die of this disease in the world every year. Dogs are responsible for most human deaths. Other viral zoonoses are avian influenza, Crimean-Congo hemorrhagic fever, Ebola and Rift Valley fever.
Fungi: Dermatophytoses are superficial mycoses that may be acquired from infected animals and affect the skin, hair and nails of humans, causing itching, redness, scaling and hair loss. Another mycotic infection that can be zoonotic is sporotrichosis.
