Others may revisit these choices as the fall unfolds. Yet many parents also need to go with what their school systems offer.<\/p>\n<p>With over a year\u2019s worth of data on how SARS-CoV-2 infection and disease manifest in children and our experience from last year\u2019s school closures, we can at least answer some important questions about the risks of infection in unvaccinated children and the risks of missing in-person school.<\/p>\n<h4><strong>What are the risks of SARS-CoV-2 infection in unvaccinated children?<\/strong><\/h4>\n<p>Children infected with SARS-CoV-2 may be asymptomatic. A\u00a0<a href=\"https:\/\/www.pnas.org\/content\/118\/34\/e2109229118\">review of several studies<\/a>\u00a0found that roughly half of infected children did not show any symptoms. A study of children in Alberta found that\u00a0<a href=\"https:\/\/doi.org\/10.1503\/cmaj.202065\">one-third of those infected were asymptomatic<\/a>.<\/p>\n<p>Children with COVID-19 symptoms, in general, have a mild illness.<\/p>\n<p>A large study in the United Kingdom, that included data up to February 2021, showed that when children aged five to 11 have symptoms, these tend to last five days. In 3.1 per cent of this age group,\u00a0<a href=\"https:\/\/doi.org\/10.1016\/S2352-4642(21)00198-X\">symptoms last longer than<\/a>\u00a028 days. This duration can be compared with people aged 12 to 17, and adults: 5.1 per cent of the former had symptoms for longer than 28 days; 13.3 per cent of adults had symptoms one month after infection. Only six of 445 younger children (1.3 per cent) included in the U.K. study had symptoms that lasted longer than 56 days.<\/p>\n<p>In children, the risk of hospitalization, severe disease and death is low,\u00a0<a href=\"https:\/\/www.cdc.gov\/coronavirus\/2019-ncov\/covid-data\/investigations-discovery\/hospitalization-death-by-age.html\">relative to adults<\/a>.<\/p>\n<p><a href=\"https:\/\/www.aap.org\/en\/pages\/2019-novel-coronavirus-covid-19-infections\/children-and-covid-19-state-level-data-report\/\">In the United States<\/a>, 0.2 to 1.9 per cent of COVID-19 cases detected in children led to hospitalization, including children infected with the now-circulating Delta variant.<\/p>\n<p>In Belgium, hospitalization rates and admission to intensive care units for children with COVID-19 have been low, and\u00a0<a href=\"https:\/\/covid-19.sciensano.be\/sites\/default\/files\/Covid19\/COVID-19_Hospital_epidemiology_Part_1.pdf\">haven\u2019t changed while new variants have been circulating<\/a>.
