a
Numbers in parentheses indicate the number of isolates within the clusters.
b
One cluster containing several isolates was regarded as one pattern.
c
Proportion of isolates from China, Mongolia, Hong Kong, Korea, and the Philippines with eight or more copies, 95% ± 5%; proportion of isolates from Thailand, Malaysia, and Vietnam with eight or more copies, 60% ± 4%.
d
The eight countries could be divided into three groups by mode number of copies.
