DETROIT – Recently people have been asking about how many variants of COVID-19 actually exist.
The answer is that there is a huge number of variants, but internationally we are primarily focused on only three right now.
That is because the mutations that make them up have changed some important way the virus behaves, whether it is the ability to spread or the ability to evade immunity.
Within the US we are also concerned about and more closely following a variant that has been described in California.
Another frequently asked question is about how the new variants are being found.
The answer is that labs around the world are constantly doing gene sequencing on samples taken from infected patients.
Those viral sequences are compared to the original sequence and sequences that have been found since then.
When significant differences are found that gives rise to new variants. Finding new variants, especially ones that are spreading faster is dependent on running these sequences.
Finally, a viewer wants to know how similar the United Kingdom variant is to the South African variant.
The answer is that some of the mutations that make up the South African variant are also found in the United Kingdom variant, but there are some significant differences, enough so that the South African variant really deserves its own discussion.
