Bird Flu Mutations Spark Pandemic Fears
A recent human death from avian influenza (H5N1) in Louisiana, linked to exposure from infected backyard chickens, highlights the virus’s increasing threat to humans. The virus has shown concerning mutations mirroring a similar case in British Columbia, increasing its potential for human-to-human transmission. Widespread influenza testing, while helpful for monitoring, also raises concerns about potential viral reassortment, creating a more dangerous strain. Sustained animal-to-animal transmission in mammals like ferrets and dairy cows further fuels this threat, emphasizing the need for increased surveillance and biosecurity measures within the dairy industry and other animal sectors.
