Health inequities, One Health and the fight against climate change: challenges in public health

Living conditions are responsible for health inequities that are systematic, unfair and avoidable between social, economic, demographic and geographic groups of the population. Thus, the groups with the worst health are those that are most socially disadvantaged. They are addressed through public policies focused on the axes of inequity. Moreover, the Covid pandemic has highlighted the intimate and fragile relationship between human health, animals and the environment. Emerging and re-emerging communicable diseases are currently affecting humans on a large scale and with diverse consequences, and although this is due to a multifactorial process, climate change is undoubtedly one of the most influential factors.
