In an intriguing study, the NSP6 L260F mutation was found to be more prevalent in the lungs of mink infected in experiments. This shift might indicate a change in viral preference towards the lungs over the upper respiratory tract, possibly explaining why the revertant virus showed reduced severity in our research.

Fascinating discovery about the NSP6 L260F mutation indicating a potential shift in viral preference towards the lungs in mink. This could explain the reduced severity of the revertant virus. 🦠🔬
