The government is reportedly considering closing schools throughout January as it’s thought the new coronavirus strain could infect kids more easily, according to the Daily Telegraph. Scientific experts have said that a ‘significantly higher’ percentage of children have returned a positive Covid test in recent weeks, coinciding with the rise of the new strain.
Professor Neil Ferguson, a scientist on the Government’s New and Emerging Respiratory Virus Threats advisory group (NervTag), said at a press briefing: “There is a hint that it has a higher propensity to infect children that may perhaps explain some of the differences, but we haven’t established any sort of causality on that but we can see that in the data.”
He continued: “What we’ve seen is, during the lockdown in England we saw a general distribution of the virus towards children, and that was true in the variant and the non-variant, and it is what we would expect, given that we had locked down which reduced adult contact but schools were still open.
“But what we’ve seen over the course of a five or six-week period is consistently the proportion of pillar two cases for the variant in under-15s was statistically significantly higher than the non-variant virus.
“We are still investigating the significance of that.”

Professor Ferguson added: “This is a hypothesis at the moment – it’s not been proven. But if it were true, then this might explain a significant proportion, maybe even the majority, of the transmission increase seen.
“But a lot more work needs to be done to actually explore this in more detail.”
However, fellow NervTag member Professor Wendy Barclay, who is the head of the department of infectious disease at Imperial College London, urged people to be cautious in regards to what is said about the spread among kids. She said: “We are not saying that this is a virus which specifically attacks children. We know that SARS-CoV-2, as it emerged as a virus, was not as efficient in infecting children as it was adults, and there are many hypotheses about that.
“And again, if the (new) virus is having an easier time of finding an entrance cell then that would put children on a more level playing field.”
Professor Barclay added: “Therefore children are equally susceptible perhaps to this virus as adults, and therefore given their mixing patterns, you would expect to see more children being infected.
“It’s not just the viruses specifically targeting them, but it’s just that it’s now less inhibited, if you like, to get into the children.”

According to Professor Ferguson, the most current estimates found the virus might be somewhere between 50-70% more transmissible than the old strain, and he added that NervTag now had ‘high confidence’ there is a substantial increase in transmission. However, uncertainty around the numbers means the group has not attached a final number on it, although he confirmed the new variant of the virus has spread to other parts of the country – Susan Hopkins, from Public Health England, said they were investigating a hotspot in Cumbria.
The virus, both the original and new strain, will decline over the next two weeks, according to Professor Ferguson’s best assessment of the situation. He explained: “Contact rates tend to be lower over Christmas with the tightening of Christmas measures and Tier4 for in place in the highest areas. I would hope certainly to be seeing virus decrease.
“If we do that will give us some sense of the level of controls which need to be in place, the real question then is, how much are we able to relax measures in the new year, and still retain control.”
