“The One Health approach is important to control zoonotic diseases”


“With the emergence of several new zoonotic diseases, the ‘One Health Approach’, which recognizes the interconnection between people, animals, plants and the environment, has become more important. Collaborative and multidisciplinary efforts spanning human, animal and environmental health are needed to understand the ecology of emerging zoonotic diseases, ”said Thrissur District Chief Medical Officer Dr KJ Reena.

“We see many types of zoonoses on a daily basis. They include rabies, leptospirosis, bird flu, Nipah, salmonella and many more. We have taken an interdisciplinary approach to dealing with them, ”said the DMO.

“One approach to health involves experts from medicine, animal health, epidemiology, wildlife, agriculture, ecology and more to understand how the disease spreads and how to control them. . “

“One of the key aspects of the One Health approach is that animals can serve as early warning signs of human illness. Thus, tracking animal health issues can help check for potential epidemics in humans. “

“Among contagious diseases, more than 65% are zoonoses. Studies indicate that even COVID 19 originated from the Wuhan animal market in China. One Health has become the one-stop-shop for controlling zoonoses and other contagious diseases, ”noted Sethu Madhavan, former director of entrepreneurship at Kerala Veterinary and Animal Sciences University.

“Along with environmental and demographic changes such as deforestation, climate change, intensive agriculture and illegal wildlife trade, global travel has also increased the risk of disease transmission,” he said. note.

“Some of the strategic options of the One Health approach include protection against zoonotic diseases; ensure food safety and security; protection of animal health and protection of trade. Compromised food safety can lead to foodborne infections and subsequent mortality. Food safety has become an important global issue due to the implications of international trade and public health, ”noted Dr Sethu Madhavan.

According to estimates by the World Health Organization, 3 to 5 billion cases of diarrhea occur worldwide each year due to food security concerns. More than 1.8 million deaths occur in children under the age of five and the bulk of these results are due to food consumption. Five lakh children under five die each year from diarrhea in India. The indiscriminate use of pesticides and antibiotic residues in the food chain will create many public health problems.
