---|---|---|---|---|
A Definitions | ||||
Matching Code | MC |  | 1–8 digits, built by linking region codes | If 1 digit, then C1 = Endemic (genotype found in one macroregion only) If 2 digits, then C1 = Localized (genotype found in two macroregions) If ≥ 3 digits, go to Area section below for further interpretation |
Area | Ar |  | numeric, n° of countries in which a given SIT is found | If MC ≥ 3 digits and Areas ≤ 5; C1 = Localized If MC ≥ 3 digits and Areas ≥ 6; C1 = Ubiquitous (genotype found in more than three macroregions) |
Spreading Index | SI |  | numeric, mean indicator of spreading independent of geography SI = n/Ar where n is the absolute value for a given shared-type | If SI ≥ 25; C2 = Epidemic If 10 < SI < 24; C2 = Common If 3 < SI < 9; C2 = Recurrent If SI ≤ 2; C2 = Rare |
