A strain of bird flu that originally broke out in the spring of 2022 has continued to spread globally, affecting millions of chickens across the northern hemisphere and subsequently infiltrating regions typically resistant to the virus. The infection has been marked by its resilience to seasonal conditions and its ability to affect a wider range of wild birds, leading to concerns over its rapid transmission and impact on poultry farms. This worrying trend has escalated fears, especially with the virus's inroads into South America, including Brazil, the world's leading chicken exporter. The bird flu outbreak has disrupted poultry industries across Europe, Asia, and Africa, resulting in record high egg prices and significant poultry culls. The situation is further exacerbated by the virus's propensity to bypass standard preventive measures, raising alarm about its potential to cause widespread disruption to global poultry markets and food supplies, particularly impacting the poorer populations that rely on chicken as a primary source of protein.
