Phylogenetic analysis of Plasmodium vivax strains from blood samples from malaria patients, Florida, USA, May–July 2023, suggesting Central/South America origin. A) Geographic distribution of 53 high-quality global strains selected from >1,000 global P. vivax collections. B) Florida P. vivax strains clustering with Central/South America strains. A phylogenetic tree was constructed by using the maximum-likelihood method, and 1,000 bootstrap replications were performed and shown next to the branches. The color coding of the geographic origin of the isolates matches the global map in panel A. The US and Central/South American cluster is shaded gray. Scale bar indicates nucleotide substitutions per site.
