Will influenza A(H3N8) cause a major public health threat?

Since the start of the COVID-19 pandemic, influenza has recorded the lowest numbers in decades worldwide. Currently, two subtypes of influenza A (H1N1 and H3N2) and two influenza B lineages (Victoria and Yamagata) are circulating in the human population. H2N2 is another influenza subtype that circulated in humans between 1957 and 1968, causing the Asian flu pandemic. All three subtypes (H1, H2, and H3) originated from birds, resulting in three pandemics that claimed the lives of millions of people.
