The new coronavirus strain could infect children more easily

Scientists have warned that a new mutant strain of coronavirus that is spreading rapidly in the UK and many other parts of the world could infect children more easily. Read also – Chinese Covid-19 vaccines are ready to fill the void, but will they work?

Informing reporters of the latest findings, scientists from the government’s New and Emerging Respiratory Virus Threats Advisory Group (NERVTAG) who are monitoring the variant said it has quickly become the dominant strain in southern Britain and could do the same across the UK. country.

The emergence of the mutated variant of SARS-CoV-2, which scientists say is up to 70% more transmissible than previous strains in the UK, has prompted some countries to close their borders with Britain and pushed large areas of the country to severe restrictions. the New Year period.

The new variety is dangerous for children

Early strains of the coronavirus found it harder to infect children than adults, with one explanation being that children have fewer gates called ACE2 receptors that the virus uses to enter cells in a human body.

Professor Wendy Barclay, of Nervtag and Imperial College London, said mutations in the virus appear to make it easier to break through those doors.

“Therefore children are equally susceptible, perhaps, to this virus as adults, and therefore, given their mixing patterns, one would expect to see more children infected,” he explained.

Experts don’t believe the new version is a greater threat to children’s health, and the scientist behind the world’s first approved COVID-19 vaccine said Pfizer / BioNTech shots will work against the strain, although further investigation remains in the course.

New Covid variety: what we know so far!

The mutated coronavirus strain spreading in the UK is 56% more transmissible than other strains, according to a study from the Center for Mathematical Modeling of Infectious Diseases at the London School of Hygiene and Tropical Medicine.

The variant was identified in genomic surveillance by COVID-19 Genomics UK (COG-UK), a consortium that analyzes genome sequencing data from the UK. COG-UK is the largest contributor to the global Covid-19 GISAID database.

The variant is the result of multiple mutations in the spike protein of the novel SARS-CoV-2 coronavirus, as well as mutations in other genomic regions of the RNA virus. Preliminary analysis suggests that it is more transmissible than previously circulating variants. COG-UK has identified one of these mutations as “N501Y”, in an area of ​​the spike protein that binds to a key protein in the human cell, the ACE2 receptor. This was an indication that the alterations could, in theory, lead the virus to become more contagious.

Symptoms of the new variant of the Covid virus

In addition to the three most common symptoms of COVID-19 such as fever, dry cough, and loss of smell and taste, 7 other symptoms have been associated with the new coronavirus strain. The following are the signs to watch out for.

– Tiredness

– Loss of appetite

– Headache

– Diarrhea

– Mental confusion

– Muscle aches
