The median genetic distance between the strain on top of the genotype or subgenotype and other strains in the same group is used as the median percentage of sequence similarity.
D-for-E substitution is shared by TW/69 and TW/95-3 in genotype III.
Residue E is retained in AE 232/1/96 of genotype VIIb.
Residue T is not retained in ZA-5/68 of genotype VIII or in TW/69 and TW/95-3 of genotype III.
Only one value was obtained, so no median or range is given.
e V-for-I substitution is shared by ZA-5/68 grouped in genotype VIII.
V-for-I substitution in genotype VII is shared by TW/69 and TW/95-3 in genotype III and AF2240 in genotype VIII.
No complete sequence of the F genes is available.
S-for-T substitution is shared by GB 1168/84 in genotype VIb.
I-for-M substitution is shared by Ch-F48E9/44 in genotype III.
—, genetic identity with the consensus.
