In the past two years, bird flu has caused significant devastation among wild and domestic bird populations worldwide. The virus has also affected various other animals, including seals, sea lions, minks, cats, dogs, skunks, foxes, and even a polar bear. Surprisingly, human cases have been relatively rare, prompting experts to delve into the reasons behind this phenomenon.

Researchers suggest that differences in how the virus infects various species, as well as variations in the microscopic receptors needed for viral replication, may explain the limited impact on humans. However, the uncertainty surrounding the potential for the virus to evolve and pose a greater threat remains a cause for concern.
