What are the India, Brazil, South Africa and UK variants?

Anxiety is growing about สมัครสล็อต a coronavirus variant, first identified in India, that appears to be spreading in the UK.

The concern is that certain new variants of the virus, like this one, may be able to spread more easily, make people sicker, or overpower vaccines.

What is happening with the India variant in the UK?
There are a few "India" variants, but one called B.1.617.2 appears to be spreading more quickly than the other two in the UK.

Sources say it is now being seen in lots of places, with few cases linked to travel, and numbers have been "grossly underestimated".

Surge testing is being used to identify these infections, but it may not be stopping the spread.

Over-18s can now book a Covid jab in parts of Lancashire after the Indian variant was found there.

What do we know about the different variants?
There are thousands of different variants of Covid circulating across the world.

Viruses mutate all the time and most changes are inconsequential. Some even harm the virus. But others can make the disease more infectious or threatening - and these mutations tend to dominate.

Are they more dangerous?
There is no evidence that any of them cause much more serious illness for the vast majority of people.

As with the original version, the risk remains highest for people who are elderly or have significant underlying health conditions.

But a virus being more infectious and equally dangerous will in itself lead to more deaths in an unvaccinated population.

Some research suggests the UK variant may be associated with a 30% higher risk of death in individuals, but the evidence is not conclusive.
