An investigation of spatial-temporal patterns and predictions of the coronavirus 2019 pandemic in Colombia, 2020–2021

Global Maximum Likelihood (ML) tree for SARS-CoV-2 genomic data analyzed in the paper.
The leaves of the tree are Colombian sequences of SARS-CoV-2 sampled between February 27, 2020, and April 5, 2020 (highlighted in red) and background sequences sampled from around the globe for genomic context. Colombian sequences are distributed among different lineages, indicating multiple virus introductions. The largest estimated intra-Colombian cluster (i.e., a monophyletic clade consisting solely of Colombian sequences) was analyzed using an exponential growth coalescent model to estimate the intra-country basic reproduction number.
