SARS-CoV-2 added real-time genome dashboards. The public learned lineage names that influenza scientists had used more quietly for decades. A reassortant H2N2 subtype replaced H1N1 in humans — a classic antigenic-shift pandemic.
Another HA shift produced H3N2, still a major seasonal actor after decades of drift. Human cases of avian H5N1 raised zoonotic-shift fears; control focused on birds and exposure, not home experiments.

SARS-CoV-2 added real-time genome dashboards. The public learned lineage names that influenza scientists had used more quietly for decades. A reassortant H2N2 subtype replaced H1N1 in humans — a classic antigenic-shift pandemic.
Another HA shift produced H3N2, still a major seasonal actor after decades of drift. Human cases of avian H5N1 raised zoonotic-shift fears; control focused on birds and exposure, not home experiments.
A triple-reassortant H1N1 spread globally; seasonal H1N1 was displaced. Vaccines were updated the following season. WHO VOC labels marked lineages with different spread and immune-escape profiles in 2021–22.
A new name in the news usually means a cluster is rising in sequence databases and case curves, not that physics changed. Zoonotic subtypes are watched because shift historically involved animal reservoirs — observation, not a protocol.
This is education from the atlas. It does not diagnose and does not prescribe a dose. It does not replace the full topic page.
