Diseases in Nature Communicable to humans

Diseases in Nature Communicable to Humans are known as zoonotic diseases—infections that are naturally transmitted between animals and humans. These diseases originate in wildlife, livestock, or domestic animals and can spread to humans through direct contact, bites, contaminated food or water, vectors such as mosquitoes and ticks, or environmental exposure. Common examples include rabies, avian influenza, Ebola, COVID-19, brucellosis, and Lyme disease. Environmental changes such as deforestation, climate change, urbanization, and wildlife trade increase human–animal interactions, raising the risk of zoonotic spillover. From a public health perspective, preventing zoonotic diseases requires a One Health approach that integrates human, animal, and environmental health. Strategies include disease surveillance, vaccination of animals, vector control, food safety measures, and public education. Understanding diseases in nature communicable to humans is essential for outbreak prevention, global health security, and reducing future pandemic risks.
