That is, the ability of children to pass the virus is about 63 percent compared to adults.<\/p>\n\n\n\n<p>Children are also less likely to produce positive PCR tests, which looks for genetic material of the virus, even when they have the virus.<\/p>\n\n\n\n<p>This could explain why kids have lower diagnosis rates across the globe.<\/p>\n\n\n\n<p>\u201cAfter monitoring the [COVID-19] pandemic for over a year, the data are clear,\u201d said Dr. Robert Hamilton, a pediatrician at Providence Saint John\u2019s Health Center, \u201cchildren have been spared the ravages of this illness.\u201d<\/p>\n\n\n\n<p>\u201cAround the world, study after study has shown that children and adolescents account for only 1 to 3 percent of all cases, and that even fewer ultimately required hospitalization,\u201d Hamilton said.<\/p>\n\n\n\n<p><strong>Why are kids less susceptible to COVID-19?<\/strong><\/p>\n\n\n\n<p>Dr. Amy Baxter, a clinical associate professor at the Medical College of Georgia at Augusta University, and CEO of PainCareLabs, suspects children are less affected by COVID-19 because of their underdeveloped sinuses.<\/p>\n\n\n\n<p>\u201cSARS-CoV-2 replicates in the nasopharynx, and children have extremely underdeveloped sinuses until about age 12,\u201d Baxter told Healthline.<\/p>\n\n\n\n<p>Baxter pointed out that even when children test positive for COVID-19, they may be less likely to transmit SARS-CoV-2.<\/p>\n\n\n\n<p>\u201cEven if the swab seems to show the same viral load, the tank size is so much different that kids\u2019 immune systems aren\u2019t triggered in the same way because they likely don\u2019t absorb nearly as many copies of [the] virus,\u201d Baxter said.<\/p>\n\n\n\n<p>SARS-CoV-2 is usually nasally inhaled before it develops into COVID-19. From there, it travels past the nose and into the nasal cavities where the virus latches onto certain receptors called ACE2 and makes copies of itself to create an infection.<\/p>\n\n\n\n<p>Dr. Kathleen Jordan, an infectious disease specialist and senior vice president of medical affairs at the women\u2019s health provider Tia, suspects the lower attack rate in kids has to do with the fact that children generally don\u2019t have as many health conditions or comorbidities as adults.<\/p>\n\n\n\n<p>The Centers for Disease Control and Prevention (CDC)<\/p>\n\n\n\n<p>lists obesity and type 2 diabetes as health conditions that can increase the risk of severe COVID-19.<\/p>\n\n\n\n<p>Jordan thinks it\u2019s a \u201ccombination of higher comorbidities in adults that increase their risk while some characteristics unique to children also protect them, such as immune characteristics and decreased propensity to clotting and inflammatory disorders in general.\u201d<\/p>\n\n\n\n<p>But there are many other theories scientists are looking into.<\/p>\n\n\n\n<p>Kids may have higher immunity from other seasonal coronaviruses<\/p>\n\n\n\n<p>that cause the common cold.<\/p>\n\n\n\n<p>\u201cImmunity to these coronavirus cousins of [SARS-CoV-2] viruses seems to confer some protection against [COVID-19] as well,\u201d Hamilton said.<\/p>\n\n\n\n<p>This crossover immunity may keep their immune systems sharp and ready to attack the novel coronavirus.<\/p>\n\n\n\n<p>\u201cIt may be that age is the best protection for COVID,\u201d Nachman noted.<\/p>\n\n\n\n<p>There may be differences in microbiota, vitamin D levels, and melatonin that provide some degree of protection.<\/p>\n\n\n\n<p>\u201cThese tempered pathways may play a role in why the disease is so much milder in children and less likely to cause symptoms or end organ damage as seen by these pathways in adults,\u201d Jordan said.<\/p>\n\n\n\n<p><strong>What this means for community transmission<\/strong><\/p>\n\n\n\n<p>More research is needed to better understand kids\u2019 role in transmitting the virus that causes COVID-19, specifically if and how schools and childcare centers fuel transmission.<\/p>\n\n\n\n<p>However, children are not thought to be key drivers of transmission in schools or their communities.<\/p>\n\n\n\n<p>A study from Ireland evaluating 40,000 people found that kids under 15 were half as likely to get and pass the coronavirus.<\/p>\n\n\n\n<p>Still, kids can contract SARS-CoV-2, and COVID-19 spreads wherever humans interact, schools and childcare facilities included.<\/p>\n\n\n\n<p>But given the growing evidence, Hamilton said many researchers and physicians feel the risks of keeping kids out of school \u2014 like depression and anxiety \u2014 are greater than the risk of contracting the new coronavirus in a school setting.<\/p>\n\n\n\n<p>Podding, physical distancing, and mask wearing are effective measures for mitigating transmission in schools, Jordan noted.<\/p>\n\n\n\n<p>\u201cWe have seen that school is the safest place for our children,\u201d Nachman said. \u201cIn pretty much each school that is open to in-person learning, and with masking and some part of social distancing, there is almost no transmission of virus.\u201d<\/p>\n\n\n\n<p><strong>The bottom line<\/strong><\/p>\n\n\n\n<p>A new model from researchers in Israel found that kids are half as susceptible to COVID-19 compared to adults.<\/p>\n\n\n\n<p>They\u2019re also less likely to transmit the illness and tend to produce negative PCR tests even when they have the virus.<\/p>\n\n\n\n<p>Infectious disease specialists say there\u2019s multiple factors that seem to protect children, such as immunity to seasonal coronaviruses, underdeveloped sinuses, and less comorbidities.<\/p>\n\n\n\n<p>Given the evidence, many health experts believe the benefits of in-school learning outweigh the risks of contracting the coronavirus in a school setting.<\/p>\n\n\n\n<p>Still, COVID-19 spreads wherever humans are, so mitigation measures such as face masking, physical distancing, and pod learning can help offset disease transmissions in childcare and learning facilities.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><a
