Fig. 2: Temporal distribution of clusters, pairs and singletons.

A Notifications of gonorrhoea infections in Victoria between January 2017 and June 2021 (inclusive). The proportion of genomes sequenced out of total notifications is shown. The dashed vertical line represents the date of the Australian international border closure (20th March 2020). The grey regions represent social restrictions within the state of Victoria. B Clusters of Neisseria gonorrhoeae genomes in Victoria, Australia, 2017. Genomes are classified according to whether they are single isolates, pairs (2 isolates) or in a cluster ( ≥ 3 isolates). Each pair or cluster contains all individuals with isolates related by ≤ 7 pairwise allelic differences using single-linkage hierarchical clustering. Each dot represents an isolate from an individual, and each cluster is plotted along a horizontal line, representing date of sample collection.
