Fig 5
Annual variation trend of keywords in plague research (2016-2025).
Among the top 20 keywords, 17 were common to both phases, 3 appeared only in the first phase (“Yersinia” “Mouse” “Protection”), and 3 appeared only in the second phase (“Phylogenetic Analysis” “Public Health” “Madagascar”). To more clearly demonstrate keyword changes over the decade, the 26 keywords are divided into two subfigures.
