Bubble plot† illustrating the distribution of clinical symptoms among patients infected with different dengue virus (DENV) serotypes in Karnataka, India (n = 23).
†Each bubble’s size corresponds to the number of patients exhibiting that symptom, with colour intensity further reflecting the count.

Evolutionary analysis by the Maximum Likelihood method*.
*Phylogenetic analysis was performed using the Maximum Likelihood method and the Tamura-Nei model in MEGA 11 software [13,14]. The tree incorporated 15 aligned nucleotide sequences (456 positions after pairwise deletion), with branch support evaluated using 1,000 bootstrap replicates. The Belagavi 2024 isolate (24062 Belagavi 2024) clustered closely with the Bhopal 2023 (OR888735) strain (bootstrap value = 63), indicating recent shared ancestry.

Heatmap infographic shows the distribution of DENV serotypes across different regions of Karnataka (2016-2024) *.
*The colour intensity reflects the proportion of each serotype, making it easy to visualise the dominance of specific serotypes in each region.
