Figure 1: mutation sites with amino acid substitution in spike protein found in Southeast Asia
Figure 2: The 10 most recurrent mutations identified from the randomly selected 60 strains in Southeast Asia with percentage of mutations compared with world-wide frequencies.
Figure 3: Phylogenetic relations of selected 60 SARS-CoV-2 strain sequences separated into four clusters
Figure 4: The cluster based time-plot of 187 complete genome sequences available in GISAID from January to May 2020. Bar charts indicate the frequency of mutants identified in first 15 days of the respective month. Line graph indicates the number of COVID-19 infections of the respective whole month.
Figure 5: A total of 78 non-synonymous mutations found in 60 sequences in Southeast Asia. Red marks in the heat map showing the countries having these mutations in high frequencies.
Figure 6: Transmission map constructed by Nextstrain with 329 sequences showing possible transmission routes into 6 Southeast Asian countries. This map is also separated the sequences of different clades.
