Design and implementation of SARS-CoV-2 variation spatio-temporal analysis system

Coronavirus disease 2019 (COVID-19) has now entered a global pandemic state, and outbreaks have occurred in many countries The latest research findings on the new crown published by the US Centers for Disease Control and Prevention (US CDC) journal "Emerging Infectious Diseases" show that the median number of SARS-Cov-2's basic reproduction number is as high as 5 7, which means that COVID-19 may be among the population in the future and continue to spread and mutate How to monitor the variation of the virus is of great significance for the research of coronavirus and drug development In this paper, based on the virus sequence data from GISAID, we designed and implemented a SARS-CoV-2 variationspatio-temporal analysis system The system can count the number of SARS-CoV-2 sequences from different countries and regions, analyze and visualize the variation of virus sequences at different times and in different spaces, and also supports the alignment of different virus sequences The system provides support for the research of COVID-19 and the decision-making of government disease control agencies
