Infectious diseases impact public health on a global scale and come with a heavy personal burden for patients and a high economical burden. Detecting and controlling pathogen outbreaks early is key to protecting public health.
The role of bioinformatics: Modern bioinformatics can analyze and compare pathogen isolates at the level of whole genomes. Comparing genomic information of isolates in context of epidemiological metadata allows investigators to track a pathogen outbreak back to its source.
Whole genome analysis also serves the purpose of characterizing pathogens, for instance revealing genes contributing to antimicrobial resistance. Such information can be crucial for optimal outbreak control. Metagenomics enables early detection of pathogens in metagenomic samples.
Quality control of microbes that modulate microbiomes is another important task and requires a different type of genomics-based analytics: typing at strain- and gene level via whole genome analysis level becomes important.
