Covid: Which areas are being surge tested for variants?
Extra Covid tests are ดาวน์โหลด slotxo taking place across England and Scotland in areas where new variants have been found.
This is known as surge testing – its purpose is to stop the spread of new forms of Covid at the very earliest stage.
How does surge testing work?
Increased testing and enhanced contact tracing is carried out in very specific locations – local authority areas, postcodes or even individual streets.Some of this is carried out by health officials going door-to-door. It includes testing people who do not have Covid symptoms.

What are the new variants?
Scientists have identified a number of “variants of concern” – these are newly spotted versions of Covid, which could be more contagious.Also, because they’re newer, less is known about how they respond to current vaccines.
The Delta variant – first identified in India – is the latest to cause concern. Others include those first identified in Brazil, South Africa and the UK (Kent).
The variants were initially named after the place where they were first seen, but the World Health Organization (WHO) has announced a new naming system which uses Greek letters instead.
