來源 https://reurl.cc/Njzg9e 原新聞 https://reurl.cc/ar6ggl 研究期刊 https://reurl.cc/vD922e https://reurl.cc/oLO66v ---- 原標題 New Evidence Suggests Young Children Spread Covid-19 More Efficiently Than Adults 新證據顯示幼兒傳播新冠肺炎的效率比成人更高 Two new studies, though from different parts of the world, have arrived at the same conclusion: that young children not only transmit SARS-CoV-2 efficiently, but may be major drivers of the pandemic as well. 兩個在不同國家的新研究得到了相同的結論-幼兒不僅可有效傳播新冠肺炎，而且也可能是大流行的主要驅動因素。 The Chicago study examines the concentration of the SARS-CoV-2 in the nasopharynx, or the upper region of the throat that connects to the nasal passages, of children and adults. According to the results, children 5 years and younger who develop mild to moderate Covid-19 symptoms have 10 to 100 times as much SARS-CoV-2 in the nasopharynx as older children and adults. 芝加哥的研究檢查了兒童和成人鼻咽或連接鼻道的喉嚨上部區域中病毒的濃度。結果顯示，出現輕度至中度症狀的5歲以下兒童的鼻咽中病毒的數量是較年長兒童和成人的10至100倍。 Whenever these young children cough, sneeze, or shout, they expel virus-laden droplets from the nasopharynx into the air. If they have as much as one hundred times the amount of virus in their throat and nasal passages as adults, it only makes sense that they would spread the virus more efficiently. 當這些幼兒咳嗽打噴嚏或大叫時，他們將病毒的飛沫從鼻咽噴到空中。如果他們的喉嚨和鼻腔中的病毒數量是成年人的一百倍，那麼他們可以更有效地傳播病毒。 The authors conclude it is likely that young children, while not as prone to suffering from Covid-19 infection, still drive its spread—just as they do with several other respiratory diseases. 作者的結論是，幼兒雖然較不易感染新冠肺炎，仍會像其他呼吸系統疾病一樣繼續傳播它。 The second manuscript reports the results of an extensive contact tracing study conducted in Trento, an autonomous region in Northern Italy. 第二份研究來自在義大利 The researchers found that although young children had a somewhat lower risk of infection than adults and were less likely to become ill, children age 14 and younger transmit the virus more efficiently to other children and adults than adults themselves. 研究人員發現，儘管年幼的兒童比成人的感染風險要低一些，而且患病的可能性較小，14歲以下的兒童比成人本身更有效地將病毒傳播給其他兒童和成人。 Their risk of transmitting Covid-19 was 22.4 percent—more than twice that of adults aged 30 to 49, whose rate of contagiousness was about 11 percent.你lthough childhood contacts were less likely to become cases,” they wrote, “children were more likely to infect household members.” 兒童傳播新冠肺炎的風險是22.4％，是30至49歲成年人（其傳染性約為11％）的兩倍多，兒童更容易感染家庭成員。 The younger the child, they noted, the higher the concentration of SARS-CoV-2 in their nasal passages—an observation consistent with the Chicago study. 研究者說孩子越小，鼻腔通道中病毒的濃度越高，這一觀察結果與芝加哥研究一致。 If children from ages 5 to 17 are as or possibly even more contagious than adults, then opening schools in areas where daily rates of infection remain moderate to high is extremely risky and unwise. 如果5到17歲的兒童比成年人具有更大的傳染能力，那麼在感染率中到高的地區重新開放回學校上課是極度危險且不明智的。 ---- reddit上看到的隨便翻翻若有錯請指正感謝:) ----- Sent from JPTT on my Asus ASUS_I01WD. -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 42.77.108.253 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/Gossiping/M.1596548827.A.720.html
