B.1.351 may sound sweet to a molecular epidemiologist, but what is the alternative, other than stigmatizing geographical names? News piece at NY Times highlighting our work with WHO on a new nomenclature system for COVID-19 variants
A variant of concern first identified in Brazil has now been found in the UK. Public health officials are investigating the six cases and are deploying more testing to see if it has spread to more people. Some variants, like this one, appear to be more contagious and there are concerns vaccines may not work quite so well against them.
A new SARS-CoV-2 variant, which has dominated Covid-19 infections in Uganda and Rwanda, has been detected in South Africa. The announcement was made by Professor Tulio de Oliveira, director of the KRISP lab. However, de Oliveira told Health24 that is not a variant of concern, and that genome surveillance will monitor this and other variants
Scientists worldwide have been closely monitoring the emergence of coronavirus variants. Although there are a large number of variants, some of them have turned out to be more alarming. Professor Tulio de Oliveira provided an update on the spread of three of these, and said that two more have been placed on the WHO's watchlist.
South Africas pause of its rollout of the Oxford/AstraZeneca vaccine in response to concern about a local coronavirus variant sparked global debate and shone a spotlight on how the countrys science has become vital to understanding where the pandemic may go next.
Evidence that a variant of the coronavirus identified in South Africa might compromise immunity sparks concerns about vaccine effectiveness.
Efforts to track SARS-CoV-2 sequences have helped identify worrying variants - but researchers are blind to emerging mutations in some regions.

Genome Detective Coronavirus Typing Tool for rapid identification and characterization of novel coronavirus genomes
This is the first version of the Zika typing tool, which uses phylogenetic analysis to identify the species and genotype of the virus.
This is the first version of the Chikungunya typing tool, which uses phylogenetic analysis to identify the species and genotype of the virus.
This is the first version of the Yellow Fever typing tool, which uses phylogenetic analysis to identify the species and genotype of the virus.
This is the first version of our Arbovirus typing tool for Chikungunya, Dengue, Yellow Fever and Zika
Phylogenetic tool to identify the HIV-1 subtypes and recombinants. Query sequences are analysed for recombination using bootscanning methods. The version 3 contains new CRFs (CRF01_AE to CRF47_BF).
KRISP has been created by the coordinated effort of the University of KwaZulu-Natal (UKZN), the Technology Innovation Agency (TIA) and the South African Medical Research Countil (SAMRC).
