Clusters of Neisseria gonorrhoeae isolates in Victoria, Australia, 2017. Isolates are classified according to whether they are single isolates (top box) or in a cluster of ≥2 isolates (bottom box). Each cluster contains all individuals with isolates related by ≤10 single nucleotide polymorphisms using hierarchical single-linkage clustering. Major clusters (comprising >30 individuals) are highlighted on the timeline in the bottom box. Each dot represents an isolate from an individual, and each cluster is plotted along a horizontal line, representing date of sample collection
