Title : Selective forces driving the evolution and spread of SARS-Cov-2 genetic variants
Abstract:
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a highly infectious RNA virus that was first identified in December 2019 in Wuhan, China. It is the pathogen responsible for the present coronavirus disease 2019 (COVID-19) pandemic. A large number of genetic variants of the original Wuhan-Hu-1 strain of the virus have rapidly evolved and spread throughout the world. Selective forces driving genetic changes in SARS-CoV-2 differed between the early stages of the pandemic and later after widespread COVID-19 infection and vaccination. The different immunological and virological causes for the continuing evolution of SARS-CoV-2 variants and their rapid spread is analysed.
Audience takeaway:
• Appreciate molecular biology of RNA viruses, virus evolution and immunity to viruses
• Assist teaching of public health, epidemiology, immunology and virology
• Help develop research ideas to advance knowledge on immunity to COVID-19
• Establish and promote collaborative research links in the field
• Improve knowledge of the COVID-19 pandemic and help develop measures to mitigate its effects
