這張圖裡有什麼
看懂背後的決策。
01Season labels
Include the strain subtype and season.
02Clades
Highlight H1N1 and H3N2 separately.
03Time scale
State the reference year on the chronogram.
Use this as an illustrative communication aid; surveillance conclusions need source data and analysis.
常見問題
常見問題
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.
