What Are Zoonotic Diseases?
Zoonotic diseases (or zoonoses) are infections that spread from animals to humans. These may be caused by bacteria, viruses, parasites, or fungi. Some zoonotic infections cause mild illness, while others lead to global pandemics.
According to the World Health Organization (WHO), over 200 types of zoonotic diseases are identified, and 60–75% of new emerging infectious diseases in humans are zoonotic in origin.
Examples
Viral: COVID-19, Rabies, Nipah, Avian Flu
Bacterial: Plague, Anthrax, Salmonella
Parasitic: Toxoplasmosis, Malaria
Why rising?
Deforestation & habitat loss → more human–wildlife contact
Climate change → wider mosquito/tick spread
Industrial farming → outbreaks in livestock
Wildlife trade & wet markets → new viruses
Global travel → rapid worldwide spread
Impact
Health: Millions infected & killed yearly
Economy: COVID-19 caused trillions in losses
Society: Burden on healthcare, food, and livelihoods
Prevention (One Health approach)
Surveillance & early detection
Vaccination of animals & humans
Safe farming & hygiene practices
Protect forests & regulate wildlife trade
Public awareness & education
Bottom Line
Zoonoses are not only health issues but also environmental and social. Protecting nature and animals is key to preventing the next pandemic. 
Question: Should governments focus more on building hospitals or on preventing zoonotic diseases through environmental protection?
