Abstract Coronavirus disease 2019 (COVID-19) has become a global pandemic disease. SARS-CoV-2 variants have aroused great concern and are expected to continue spreading. Although many countries have promoted roll-out vaccination, the immune barrier has not yet been fully established, indicating that...

From South Africa and Brazil to the UK, new variants of the SARS-CoV-2 virus are regularly being discovered, coinciding with an accelerating international vaccination program. Although this is a normal development, these latest variants are causing alarm. They are fast-spreading, i...
Co-infections with different variants of SARS-CoV-2 are a key precursor to recombination events that are likely to drive SARS-CoV-2 evolution. Rapid identification of such co-infections is required to determine their frequency in the community, particula
A large study from Ontario confirms that SARS-CoV-2 variants of concern (VOCs), especially the Delta variant, are more virulent than the native strain of the virus, increasing people's risk of hospitalization, admission to the intensive care unit (ICU) a
