Several studies using mathematical modelling of the COVID-19 incidence and other coronavirus infections have suggested the effectiveness of disease control such as social distancing and city lockdown [6, 7] , but these methods seldom assess individual transmission It is evident in literature that genomic information of pathogens provide valuable empirical information about their transmission histories [2] , such as the identification of transmission chains through phylogenetic analysis of the genome sequences as illustrated in the work done by Lu et al. In addition to revealing the evolutionary process of the pathogen and acting as a proxy of disease transmission history, phylogenetic trees also serve as versatile frameworks for comparative analysis of virus genetics and phenotypes, disease epidemiology and clinical manifestations, and population demography and environment, thus facilitating identification of a possible interplay between these various aspects in disease dynamics ( Figure 1 ).	./cache/cord-342539-o004ggon.txt	./txt/cord-342539-o004ggon.txt
