"The new, highly-contagious Delta variant — spread with the ease of chickenpox — is causing COVID-19 cases to skyrocket across the globe as health officials respond with alarm. “The war has changed,” said a recent internal U.S. Centers for Disease Control and Prevention (CDC) document.
Globally, numerous infectious diseases are being transmitted between wildlife, livestock and humans at escalating rates, including outbreaks of COVID-19, Ebola, dengue, HIV and others, as the threat of new emergent zoonotic diseases grows ever greater. The cost is huge in lives lost and ruined economies.
The driver: human activities, particularly intrusion into wild landscapes and eating and trading wild animals. Bringing people, domestic and wild animals into unnatural proximity exposes all to pathogens for which they lack immunity. International travel and a booming global wildlife trade quickly spread viruses.
Experts say that a “One Health” approach is urgently needed to prevent future pandemics — simultaneously addressing human, animal and ecosystem health, protecting humanity and nature, and incorporating disease risk into decision-making."
