Note that this says nothing about long term consequences, i.e. Long Covid, which we've only just started acknowledging when it comes to adults.<p>Polio was asymptomatic in 95% of cases and most of the symptomatic cases were unspecific and mild, but now we know that it can be followed by the much more severe Post-Polio Syndrome even 3-5 decades after the original infection, which may affect almost 30% of all cases, including the asymptomatic ones.<p>That children are unlikely to die or have severe complications from Covid doesn't mean it's safe to allow children to be infected, even if we ignore that this could make them asymptomatic carriers infecting at-risk family members who may not be able to get vaccinated for health reasons.<p>EDIT: If you find the time to downvote this comment, also check out nojito's link to the paper about Long Covid in children: <a href="https://news.ycombinator.com/item?id=27793752" rel="nofollow">https://news.ycombinator.com/item?id=27793752</a><p>If the lower estimate of 20% of Covid cases resulting in Long Covid are right and we lift hygiene restrictions for children because of their "low risk" for hospitalization, that means we could see Long Covid in up to 20% of the population under 12 (assuming vaccinations become available for ages 12 and over).<p>And that's assuming the data about "low risk" is interpreted correctly. The article states that 25 dead in 12 million children translates to a death rate of 2 per million (or 0.2 in 100,000 if we want to use the same scale used for numbers about the general population) but this wrongly assumes that all of the 12 million children have at some point been Covid positive, which seems impossibly pessimistic given that there have only been 5 million recorded infections in the UK across the entire population.<p>For comparison, the ONS report[1] estimates roughly 1% of children between age 2 and school year 6 (age 10-11) having been positive with no data on ages younger than 2. This would take the number from 0.2 in 100,000 to 20 in 100,000 -- compared to the total mortality of 228.6 in 100,000[2].<p>In other words, it looks like children are only 1/10 as likely to die as adults, not 1/1000 as likely.<p>Also, the article only considers the 25 children who directly died from Covid, not the 36 children who were tested positive but died from "other causes". I'm not sure if this has changed in the UK given that you often read about "deaths within 28 days of a positive test" now, but at least for most of 2020 these 36 children would have counted towards the total death count as I understand it. If we compare the 20 in 100,000 (or 20.8 in 100,000 if we want to be pedantic about rounding) number to the "deaths within 28 days of a positive test" number we actually get slightly more than 1/10 because that rate is 192.2 in 100,000.<p>[1]: <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/healthandsocialcare/conditionsanddiseases/bulletins/coronaviruscovid19infectionsurveypilot/latest" rel="nofollow">https://www.ons.gov.uk/peoplepopulationandcommunity/healthan...</a><p>[2]: <a href="https://coronavirus.data.gov.uk/details/deaths" rel="nofollow">https://coronavirus.data.gov.uk/details/deaths</a>
