Over the past few weeks there has been widespread reporting on the emergence of new variants of SARS-CoV-2, the virus that causes COVID-19.
It is known that viruses can mutate and new variants frequently occur, however two relatively recent SARS-CoV-2 variants (one first seen in the UK and one in South Africa), have been shown to be more infectious than previous strains.
Current advice states that approved vaccines should provide protection against the variants. Public health measures including physical distancing, face masks, and limitations on large gatherings will also remain effective. However, control of a more transmissible variant may require enhanced adoption of these measures.
