The UK Health Safety Agency (UKHSA) reported that the new omicron sub-variant BA.2 appears to have a significantly higher spreadability than the current dominant BA.1. Dr. Paweł Grzesiowski, an expert of the Supreme Medical Council on COVID-19, referred to this issue on TVN24. “We’ve been repeating it from the start of the pandemic, that the COVID-19 virus is mutating all the time, changing all the time,” he said. As he added, in the case of the new sub-option, “one person will infect 10-12 more people on average”.
New omicron sub-variant denoted by BA.2 appears to have a much higher spread than the currently dominant BA.1, the British Health Safety Agency (UKHSA) reported on Friday. ‘We now know BA.2 has an increased rate of growth, which is seen in all regions of England,’ said Dr Susan Hopkins, UKHSA’s chief medical advisor.
The agency added that there was no data on the severity of the disease for BA.2 compared to BA.1, but reiterated that, according to its preliminary assessment, no difference was found between the two omicron subtypes in terms of the vaccine’s effectiveness in preventing symptomatic disease. .
Doctor Paweł Grzesiowski about the new omicron sub-option
Dr. Paweł Grzesiowski, an expert of the Supreme Medical Council on COVID-19, referred to this issue on TVN24. – We repeat it from the beginning of the pandemic, that the COVID-19 virus is mutating all the time, changing all the time and also the omicron variant, by some people called the last one, which is supposed to end the pandemic, is still changing – he said.
As he explained, “the structure of the S protein, but also of other viral proteins is constantly changing.” – At the moment, as many as 85 changes have been counted in the entire gene set of the virus compared to the first variant of the omicron, where about fifty mutations were mentioned – said Grzesiowski.
– What does that mean for us? The virus acquires new features, perfecting its structure to infect even faster and more effectively – he added.
Grzesiowski: one person will infect 10-12 people on average
Dr. Grzesiowski said that “today, the new variant of the omicron is described as similar to the measles virus”. – So infectious at the level of 10-12 people on average by one sick person. This means, first of all, that there will be even more patients and that the virus will cause an increase in the number of cases even faster, he explained.
– We can expect even bigger problems, both in health care and in other areas of life – he added.
