“We have always known that major epidemics often originate in the animal world”

For ten years, the United Nations (UN), through the World Health Organization (WHO), has been trying to impose the concept of “One Health”. This notion highlights the interdependence of human, animal and ecosystem health. Fleetingly popularized during the Covid-19 epidemic, it is struggling to establish itself in public policies and public opinion. However, all it takes is stagnant water – ideal for mosquitoes – and a malaria epidemic can develop. Deforestation, strong urbanization, and disturbed bats can contaminate mammals. Overuse of antibiotics and resistant viruses are emerging. Environment, health and society are closely linked. How can we advance the idea of ​​“One Health”? Brigitte Autran heads Covars, an independent scientific committee created at the end of the health emergency law, in support of the Minister of Health and Research and the Prime Minister, to help them anticipate health risks .

How did the notion of One Health emerge?

Covid has highlighted the fact that 75% to 80% of emerging infections in humans are of animal origin. To better anticipate this risk, it is necessary to have a joint and parallel analysis of the pathologies likely to emerge from the animal world and be transmitted to humans. Covid-19 was an illustration of this, since we know that the virus emerged in bats. The government therefore considered that it was very important to include this concept of “One Health” in the Covars missions.

The first interactions between man and animals are extremely old, and we have always known in the history of diseases that major epidemics often originate in the animal world. For example, plague epidemics as we have known them since Antiquity. This reality was highlighted at the beginning of the 21st^e century with several major epidemics such as SARS [syndrome respiratoire aigu sévère]in 2002-2004, MERS-CoV [coronavirus du syndrome respiratoire du Moyen-Orient]in 2012, pandemic episodes of influenza originating from birds or the animal world… This concept of One Health was gradually highlighted.

Has the Covid-19 crisis accelerated the consideration of these interactions?
