The virus that causes COVID-19 is from a large family of viruses called coronavirus.
Coronaviruses are named for the crown-like spikes on their surfaces. Scientists monitor changes in the virus, including changes to the spikes on the surface of the virus.
Multiple COVID-19 variants are circulating globally.
The UK coronavirus variant spreads more easily and quickly than other variants, but there is no evidence that it causes more severe illness or increased risk of death.
The Brazil variant contains a set of additional mutations that may affect its ability to be recognized by antibodies.
The South Africa variant called 1.351 shares some mutations with the variant detected in the UK.
These variants seem to spread more easily and quickly than other variants, which may lead to more cases of COVID-19.
You need to continue physical distancing, use of masks, hand hygiene, and isolation and quarantine to limiting the spread of COVID 19.
Also, get vaccinated if you can!
