Zoonoses, or zoonotic diseases, are infections that jump the species barrier, transmitting from animals to humans. These diseases are responsible for over 60% of all human infectious diseases and nearly 75% of newly emerging infections. Common zoonoses include rabies, Ebola, avian influenza, brucellosis, and more recently, COVID-19.
As global travel, urbanisation, and deforestation expand, human-animal interactions are increasing, raising the risk of spillover events. Wild animals, domestic pets, livestock, and even insects can act as reservoirs and vectors for dangerous pathogens. World Zoonoses Day is dedicated to highlighting these risks and promoting action to curb the spread of zoonotic diseases.
Significance of July 6: Honouring a Scientific Milestone
World Zoonoses Day commemorates a historic breakthrough in preventive medicine, the successful administration of the first rabies vaccine by Louis Pasteur on July 6, 1885. Pasteur’s achievement laid the foundation for modern immunology and preventive medicine, making this day a symbol of hope and scientific progress against zoonotic threats.
Beyond the scientific legacy, the day has evolved into a platform to raise awareness about the global impact of zoonotic diseases and the importance of coordinated efforts to prevent them.
Theme 2025: “One World, One Health – Prevent Zoonoses”
The 2025 theme highlights an integrated approach to disease prevention that links the health of people, animals, and ecosystems. The One Health concept is endorsed by organizations like the World Health Organization (WHO), the Food and Agriculture Organization (FAO), and the World Organisation for Animal Health (WOAH).
This holistic framework encourages collaboration among doctors, veterinarians, ecologists, and policymakers to address the root causes of zoonotic diseases. It emphasizes breaking the chain of transmission by improving sanitation, regulating animal trade, reducing habitat destruction, and strengthening early warning systems.
ISID’s Role in Global Health Security
The International Society for Infectious Diseases (ISID) is at the forefront of fostering international cooperation in tackling infectious diseases. On the occasion of World Zoonoses Day 2025, ISID reiterates its commitment to scientific exchange, education, and partnerships that bridge human, animal, and plant health sectors.
Through initiatives like the ProMED-mail alert system, global conferences, and collaborative research, ISID supports the real-time sharing of outbreak information and contributes to building a resilient global health infrastructure
Importance of Surveillance and Early Detection
Preventing zoonoses requires robust surveillance systems that monitor animal populations for unusual patterns of illness. Countries must invest in laboratory infrastructure, veterinary field services, and data-sharing platforms to detect outbreaks before they spill over into human populations.
Cross-sector training, community education, and local capacity-building are also essential. Farmers, animal handlers, and rural health workers must be equipped with the knowledge and tools to recognize early signs of zoonotic outbreaks and respond effectively.
Looking Ahead: A Call for Global Solidarity
As we observe World Zoonoses Day 2025, the message is clear: preventing zoonotic diseases is not the responsibility of one sector or nation, it requires global solidarity. The “One World, One Health” theme captures the essence of this collaborative spirit, reminding us that human well-being is deeply interlinked with that of animals and the environment.
By embracing this interconnected approach, investing in science and surveillance, and fostering global cooperation, we can prevent zoonoses and build a safer, healthier future for all.
World Zoonoses Day 2025 is more than a commemoration; it is a call to action. As the world reflects on past pandemics and braces for future challenges, the theme “One World, One Health: Prevent Zoonoses” inspires governments, scientists, and citizens to unite across boundaries. Together, through awareness, vigilance, and partnership, we can break the chain of zoonotic transmission and protect the health of generations to come.
