Europe is currently primarily concerned about the British variant of the coronavirus. But he is not the only one that threatens us. In addition to the South African and Brazilian variants, scientists are also concerned about viruses from California and New York.
- New variants of the coronavirus are rampant in the United States
- So far, we have feared the UK variant of COVID-19 the most
- US strains are causing concern among scientists
- More current information can be found on the Onet homepage.
In California, the strain described as B.1.429 / CAL.20C has become the dominant variant of the coronavirus. In February, it was detected in over 50 percent. samples subjected to genetic analysis in this state. The California variant of SARS-CoV-2 has been spreading across the state since September 2020. According to scientists, it is more contagious and may also be more resistant to vaccines against COVID-19, reports the Los Angeles Times.

According to the GISAID website, which collects global data on the coronavirus genome, infections with a California-derived variant of the coronavirus have been reported not only in the US, but also in Mexico, Australia, Japan and several European countries. In the entire US in the last four weeks, B.1.429 was detected in nearly 20 percent. sequenced samples.
Variant B.1.526 is spreading in New York. The variety has, among others the E484K mutation, which is also present in the South African (B.1.351) and Brazil (P.1 / B.1.1.28) coronavirus variant, and researchers say may be more resistant to the COVID-19 vaccines in use today.
In 94 countries around the world, infections have been diagnosed with variant B.1.1.7., Which is the dominant form of the pathogen in Great Britain since December 2020. The variety spreads quickly almost all over Europe. In several countries, including Italy and the Czech Republic, it is already the most common form of the coronavirus.
According to the European Center for Disease Prevention and Control (ECDC), the variant is more contagious and possibly at risk of more severe COVID-19, including death. The available data do not suggest that the British variant is more resistant to vaccines. However, recently in the UK, a new version of the variant was discovered in single samples in which the E484K mutation is also present, which research shows that weakens the effect of some vaccines.
The variant 501.V2 / B.1.351, which was detected in South Africa, is already present in 48 countries around the world. In addition to African countries, the largest number of cases of infection with it was recorded in the United Kingdom, France, the Benelux countries and Turkey, according to GISAID. In the last month in South Africa, this variant was detected in 100%. samples tested, and in Botswana 80 percent. It is still not a widespread variety in the European Union; in France, it was recorded in 4,8 percent. of the tested samples, in Belgium – 4,6 percent. However, the GISAID database is based on data from samples tested in terms of the genetic sequence; Worldwide, this procedure covers only a small percentage of the material collected from coronavirus-infected patients.

According to research, the variant of SARS-CoV-2, originating from South Africa, may weaken the effect of some COVID-19 vaccines. ECDC cautions that this strain is also more contagious.
In 25 countries around the world, infections with the P.1 variant belonging to the larger group described as B.1.1.28 were found. The variety is spread mainly in Brazil, but isolated cases of infections have also been reported in many European countries. Due to the presence of the E484K mutation, the variant is considered to be more resistant to vaccines. The variety is also more contagious (PAP)
