よくある質問
よくある質問
What does the seasonal label show?
It identifies the subtype and year used for each selected strain.
Why use a chronogram?
A chronogram makes the time framing of a strain comparison explicit.
Is this surveillance evidence?
No. It is an illustrative example and does not replace a sourced surveillance analysis.
