The scientific community has issued a worrying warning about the growing risk of zoonotic diseases—those that jump between species. This phenomenon, which has already caused health crises such as the COVID-19 pandemic, threatens not only human health but also the survival of countless animal species.

Climate change, deforestation, and human expansion into wild habitats are creating an environment conducive to the transmission of pathogens between species. As animals lose their natural habitat, they are forced to interact more closely with humans and other animals, facilitating the spread of viruses, bacteria, and parasites.

An alarming example is the spread of the Nipah virus, transmitted from bats to humans through crop contamination. This virus has a high mortality rate, and there is no effective treatment. Another worrying case is avian influenza, which has shown the ability to infect humans with devastating consequences. Recent outbreaks of Rift Valley fever and Hendra virus have also been identified, both with epidemic potential.

The loss of biodiversity also plays a crucial role in this problem. As the number of species decreases, pathogens have fewer host options and become concentrated in a few, increasing the likelihood of them reaching humans. This situation is exacerbated by intensive agricultural practices and the illegal wildlife trade, which create points of direct contact between species that would not normally interact.

To mitigate these risks, experts recommend a multifaceted strategy that includes protecting natural habitats, stricter regulation of the animal trade, and investment in research and epidemiological surveillance. International collaboration is also essential, as zoonotic diseases know no borders and can spread rapidly in a globalized world.
