Since the outbreak of the new coronavirus has been spreading for more than a year, everyone is no stranger to gene sequencing. Through decoding and comparison, it is possible to find out whether the relationship between the cases comes from the same batch of infection sources. Huang, Yao-ting, a professor at the Department of Information Engineering at Chung Cheng University, has been studying the gene sequencing of infectious microorganisms for many years. Seeing the difficulties of clinical tracking of unknown causes of infection in hospitals, he has recently started to build a "Taiwan Pathogen Local Database", which is expected to allow Taiwan to face the next wave of infectious diseases. , can speed up the identification of infectious pathogens. How important is pathogen tracking? In addition to analyzing pathogens that cause disease and death, it can also find similar clusters and identify emerging variants.
