Second Bird Flu Strain Found in Dairy Cattle: Experts Warn of Pandemic Risk
The US Department of Agriculture’s recent detection of a second bird flu strain in dairy cattle is undeniably alarming. This development raises serious concerns about the potential for widespread infection and the emergence of novel, highly pathogenic strains. The situation is particularly concerning given the already circulating strain, 2.3.4.4b (B3.13), which, while displaying a preference for avian receptors, demonstrates the ability to infect mammals, including humans, albeit with relatively mild symptoms in most cases. This dual infection capability introduces a significant risk.
This newly detected strain, 2.3.4.4b (D1.1), presents a far more dangerous profile. Its presence in wild birds and now in cattle is worrying because it carries a substantially higher mortality risk compared to B3.13, as evidenced by previous cases showing severe illness and even death.… Continue reading
