Kovid-19 virus with new danger mutation, according to experts
According to experts, three different variants of the new type of coronavirus (Kovid-19) detected in Wuhan, China in December 2019, mutated and emerged in the UK, South Africa and Brazil threaten the world due to the high rate of spread. .
The emergence of mutations in the global Kovid-19 outbreak with the joint work of the Turkish Society of Clinical Microbiology and Infectious Diseases (KLİMİK), the Clinical Microbiology Specialist Association (KLİMUD), the Turkish Microbiology Association (TMC) and the Public Health Specialist Association (HASUDER) and an assessment of disease risk was made.
In the assessment, which pointed out that the main risk of mutated viruses (variant viruses) is the increase in contagiousness, it was warned that all three variants, which quickly became dominant in their first emergence, could spread all over the world in a short time.
- "The variant 'B.1.1.7' emerging in the UK may prevail in mid-February"
According to the information in the assessment, this variant, which attracted attention in the UK urban area in December 2020 and named as VOC (variant of concern) 202012/01, appeared in the second half of September 2020.
The variant in question quickly spread and became dominant despite the "tight closure" measures in the south of England, especially in December.
The data obtained from the investigations so far revealed that the transmission rate and mortality rate of the mutated virus is higher. Studies have shown that it affects all age groups and the likelihood of loss of effectiveness in immune responses acquired after vaccination and natural infections is also low.
Due to the increased rate of contagion and spread, the increasing number of cases has put pressure on the healthcare system by causing the number of serious illnesses and deaths to increase.
The mutated virus, which has spread to many countries, has increased its share in intra-community transmission, especially in Ireland and Portugal, as well as Switzerland and Denmark. In mid-February in the concern may become the dominant origin mutated virus, Turkey currently many foreign trips associated with 17 provinces, 114 including the UK variant was found in 128 people.
- "Variant seen in South Africa detected in 31 countries"
According to the evaluations, the second variant, named "B.1.351", was seen during the second wave in South Africa in December 2020, despite the summer months.
Initial studies showed that this variant may be resistant to neutralization by natural infection and post-vaccination antibodies, and these mutations were found to reduce the effectiveness of some antibodies used for therapeutic purposes.
The contagiousness of this variant, which is currently dominant in South Africa, has been determined to be increased, but h
