What percentage of emerging infectious diseases are zoonotic

It is difficult to provide an exact percentage of emerging infectious diseases that are zoonotic as data might vary depending on the study or region being considered. However, zoonotic diseases are estimated to account for a significant proportion of emerging infectious diseases globally. According to the Union Health Secretary, the cautionary percentage of emerging infectious diseases that are zoonotic is around 75%. This suggests that three-quarters of newly appearing diseases that affect humans have origins in animals.

• Zoonotic diseases are caused by pathogens such as bacteria, viruses, parasites, and fungi that can be transmitted between animals and humans.
• These diseases typically arise when humans come into contact with infected animals or their environment, either directly or indirectly.
• Zoonotic diseases can have serious public health implications, leading to outbreaks and even pandemics, as seen with diseases like Ebola, COVID-19, Zika, and Avian influenza.
• The transmission of zoonotic diseases can occur through various routes, including direct contact with animals or their bodily fluids, consumption of contaminated food, or exposure to environments where animals and humans interact.
• Factors such as increased urbanization, deforestation, wildlife trade, and changes in agriculture and food production practices can contribute to the emergence and spread of zoonotic diseases.

It is crucial to pay attention to zoonotic diseases and take measures to prevent their transmission in order to safeguard public health globally.
