There's the UK Covid variant, the South African variant, the Brazilian variant and scientists in Los Angeles have found what they believe to be a Californian variant.
And a variant identified in Liverpool has been classed as a “variant under investigation”.
Experts are also studying the B.1.1.7 variant, first identified in the UK, and the 501.Y.V2 variant, first found in South Africa.
Then we’ll be ready to start testing in the challenge model with a variant virus, so we are able to respond very quickly to a variant.
At present, key variants of concern are the South African variant (501Y.V2), the Brazilian variant (P.1) and the Kent variant (B117).
The South African variant did not seem to have a distinct transmission advantage over the variant now dominant in the UK, first seen in Kent, he added.
The study authors said the variant "should likely be designated a variant of concern warranting urgent follow-up investigation," Science reported Tuesday.
The South African variant, like the new UK variant, contains a mutation known as N501Y which is believed to make the virus more contagious than older variants.
Hopkins said that if the reproduction number, R, is below 1, neither the South Africa variant nor the Kent variant with the E484K mutation should spread further.

Queensland premier Annastacia Palaszczuk announces a three-day lockdown of greater Brisbane after a hotel quarantine worker is infected with a concerning and more transmissible variant of Covid-19 known as the B117 variant.
In the UK, the Kent variant (B117), the South African variant (501Y.V2), and the Bristol variant (which is similar to B117 but has a mutation also seen in the South African variant) have been the focus of concerns.
The South African variant also contains mutations known as E484K and K417N, which appear to make the virus better able to evade neutralising antibodies produced by the body, suggesting current Covid vaccines will prove less effective against this variant.
"Positive tests will be sequenced to identify any further spread of the new variant first discovered in South Africa, enabling a better understanding of the variant and identifying if there are any more cases of this variant of the virus in the area", the council said.
The Centers for Disease Control and Prevention has called B.1.617 a variant of "interest" but hasn't gone so far as to label it a "variant of concern" yet, like the agency has done for the B.1.1.7 variant (first tracked in the UK), the B.1.351 variant (spotted in South Africa), and the P.1 variant (picked up in Brazil).
