<unk>  is the study of immunology, epidemiology, and phylogenetics of<unk>  pathogens to better understand the evolutionary role of these pathogens.<unk> analysis includes analyzing genetic diversity, natural selection, and population dynamics of infectious disease pathogen phylogenies during pandemics and studying intra-host evolution of viruses.<unk>  combines the study of phylogenetic analysis, ecological, and evolutionary processes to better understand of the mechanisms that drive spatiotemportal incidence and phylogenetic patterns of<unk>  pathogens.<unk>  uses genome-wide single-nucleotide polymorphisms (SNP) in order to better understand the evolutionary mechanism of<unk>  pathogens. Many<unk> studies have been performed on viruses, specifically RNA viruses (see Viral<unk>  which have high mutation rates. The field of<unk>  has increased substantially due to the advancement of next-generation sequencing and the amount of data available.
