The Rospotrebnadzor reported that patients infected with the “delta” variant of COVID-19 are more likely to get sick in moderate and severe forms, writes RIA News…
It is noted that the treatment for the “delta” option is more complex and lengthy. The department clarified that the most vulnerable to the new strain of COVID-19 are young people from 14 to 29 years old, since they often use public transport and have a large number of contacts.
On June 21, the Indian authorities announced the emergence of a new strain of COVID-19 “delta plus” (B.1.617.2.1). The new subspecies, according to epidemiologists, is distinguished by the presence of the K417N mutation in the spike protein. It is able to reduce the activity of antibodies of recovered and vaccinated people.
According to research results provided by the Indian Genomics Consortium SARS-CoV-2 (INSACOG), the new variant of the virus is “worrying” because it has a high spread rate and the ability to more damage lung cells. Scientists suggest that the “delta plus” may even “elude” the action of vaccines or antibodies.
Rospotrebnadzor stressed that the symptoms of the new strain of COVID-19 remain classic: fever, cough, loss of smell and taste. However, doctors also observe signs characteristic of acute respiratory viral infections and intestinal infections: runny nose, headaches, sore throat, diarrhea, less often nausea.
The head of Rospotrebnadzor, Anna Popova, said that in the last three weeks of July, among the detected cases of COVID-19, almost 70 percent fell on the “delta” strain. She noted that this is the largest figure in the entire history of observations.
The head of the department called the situation with COVID-19 in Russia tense. According to her, although the situation remains rather difficult, at the same time, there is a decrease in the weekly rate of increase in cases of coronavirus. Popova stressed that this indicates an emerging trend towards stabilization of the epidemic process.
Popova stressed that vaccines also protect against new variants of the virus. Even if a vaccinated person gets sick, the virus in his body will not begin to mutate, she added.
The representative of the World Health Organization (WHO) in Russia Melita Vujnovich, in turn, noted that the “delta” variant of the coronavirus is 50 percent more infectious than the “alpha” strain found in the UK.
Feng Zijian, a researcher at the China Center for Disease Control and Prevention, and Shao Yiming, an expert at the China Center for Disease Control and Prevention, noted that the protective effect of COVID-19 vaccines against this variant may be diminishing.
Rospotrebnadzor noted that it is impossible to determine which particular strain of coronavirus a person is infected by external signs, this can only be found by sequencing – decoding the genome of the virus or its fragment (S-protein gene) in laboratory conditions. This will allow you to determine the presence of key mutations – and then identify the strain itself.
