Figure 2

Circulation of measles virus genotypes globally reported through virologic surveillance, 1970–2019.

Figure shows year of first and last detection of measles wild-type virus genotypes. The first and last years of documented circulation reported to the MeaNS database (or GenBank before 2005) for all 24 measles virus genotypes are shown. First year detection determined from earliest reported reference strain and does not necessarily indicate first year of circulation. The four currently circulating genotypes (detected in 2019) are indicated in red (B3, D4, D8, H1). Measles vaccines were derived from genotype A which is not shown.
