SARS-CoV-2 variants of concern

For information on Variants of Concern (VOC) please see Contact Tracing guidance here.

Viruses constantly change through mutation and many variants of the SARS-CoV-2 virus have been observed worldwide. Not all mutations have a significant impact on the spread of the virus, but some can provide the virus with selective advantages, such as increased transmissibility or the ability to evade immune responses.
