There are several phylogenetic tree construction / D6 G3 O% \/ d9 U$ v1 b* f
methods that can be used to illustrate the spread of disease 0 u" E+ g' j0 w/ O) S
epidemics. One of the methods used is probability-based 7 K( r4 O& W6 y9 P
maximum likelihood. This paper explains how to identify the 4 G" d/ d2 r& e
spread of the SARS epidemic in the world using the formation of ; O- F# T% J; A P, E
phylogenetic trees using the maximum likelihood method. The 6 v* H3 ~3 a& q% t9 w$ [
