MVs/Gir Somnath.IND/42.16 D8 measles virus sequences identified in the United States, from 30 September 2018 to 31 December 2019 (n = 545). The numbers shown within individual squares indicate the total number of cases in which the named strain, MVs/Gir Somnath.IND/42.16, was identified, plotted based on the reported epidemiological week and year (columns) and the individual infection cluster (rows). Individual clusters are labeled using the reporting jurisdiction letter abbreviations, a chronological number per reporting jurisdiction, and the year in which the cluster started. Clusters with known sources (ie, in which an importation was identified) are shown in blue, and clusters with no known source are shown in gray. The red vertical dashed line represents the date of rash onset for the last case in New York State; the black vertical dashed line, the date that outbreak was declared to be over (ie, 42 days or 2 maximum incubation periods after the date of rash onset for the last case). Eight infection clusters were identified after the last case in the New York State outbreak; 3 did not have a known source (2 single cases and a 12-case multistate outbreak).
