Polish gulls harbor new coronavirus strains, spotlighting avian role in viral evolution

Researchers in Poland have identified five strains of gammacoronaviruses and deltacoronaviruses in black-headed and common gulls, shedding new light on the diversity and evolutionary potential of these viruses. The study highlights the need for ongoing research into animal reservoirs of coronaviruses, as they pose a risk for zoonotic transmission to humans.
