Influenza is the world's greatest pandemic threat based on research showing constant evolution and mutations. Each winter, influenza outbreaks occur, resembling 'little pandemics.' The strains are currently not virulent enough, but this may change in the future.
The second most likely cause of a pandemic after influenza is a yet unknown virus referred to as Disease X, according to 21% of experts. The next pandemic could arise from an unforeseen micro-organism, akin to the emergence of the Sars-CoV-2 virus.
