SSI: Unlikely to spread new variant as the British


The South African corona variant, which has been proven for the first time in Denmark, is more contagious, but not more dangerous.

On Saturday, the first case of a South African variant of coronavirus was registered in Denmark.

In line with the British variant – B117 – which has spread in Denmark, it is more contagious than variants that have been in the country so far.

This is what Tyra Grove Krause, professional director of the Statens Serum Institut (SSI), says.

– It is characterized by an increased infectivity, and has been seen to have spread in South Africa, as the B117 variant has been seen to spread in England and Ireland.

– It does not seem to be more dangerous than the other variants we know, she says.

The British are 50-74 percent more contagious than the common variants, but no figures have been set on how much the South African is contagious.

But according to Tyra Grove Krause, it shows the same pace as the B117.

Although the variant is not in itself more dangerous, it may indirectly be because it infects more.

During November, December and January, an increasing number of cases of the British variant have been found in Denmark.

Within the coming months, it could potentially become the dominant virus variant in Denmark.

Tyra Grove Krause calls it unlikely that the South African variant will spread in the same way as one sees with the British.

– It can not be ruled out that it is starting to spread more widely in Denmark, but now we only have one case so far.

– The Danish Agency for Patient Safety is intensifying infection detection, so I think it will have a hard time outcompeting B117, which already has a good roof in Denmark, she says.

Tyra Grove Krause also does not consider that additional restrictions should be introduced that are directly targeted at the infectious variants.

– There are already a number of restrictions – both in relation to travel and testing – and an intensified contact tracking is being made for these variants, so I think we do what we can, she says.

The South African variant has been found because SSI analyzes a proportion of all the positive corona samples for which variant of coronavirus they originate from.

From the start of the new year, SSI can analyze all positive test results, but it takes about a week before there is an answer as to which variant it is.

This week, the Statens Serum Institut has introduced a new coronal test, which can capture whether a particular variant has been infected – for example the British one.

However, the new test has not been developed to be able to detect the South African variant.

Instead, SSI is developing another method – spike sequencing – which within a day will be able to detect whether you have been infected with the more infectious variants.

There is no time horizon for when that method can be put into use.
