Yes of course it’s a worry. Everything about this pandemic is a worry right now.
A scientific paper said the new variant adds to the growing body of evidence that it is more transmissible than the old variant and that this is actually more worrying than an increase in the new variant's mortality - because of the exponential nature of spread, a more transmissible variant will lead to a lot more people getting Covid, and thus a lot more people dying.
But in answer to you MayBee my worrying about it won’t stop it. Let’s just pin our hopes on our very clever scientists and the fact that the government at the highest level here and world wide are aware of it and doing their best to deal with it. We can’t ask for more I guess.
