Chockablock with timely themes and connections to recent world-shaking events.” — Kirkus Reviews More than a hundred years before Covid, a deadly pneumonic plague threatened to sweep through Northeast China. Medical experts were summoned to help contain it—among them Wu Lien-teh, who had overcome hurdles to be a doctor since his boyhood in Malaysia. Unlike others, Dr. Wu deduced that the disease was spread through airborne bacteria and advocated for quarantines and other measures familiar to readers today, including the use of a face covering he designed from layers of cloth and gauze: the first version of the N95 mask. Wu Lien-teh faced ridicule and discrimination, but his trailblazing methods prevailed: the 1910 Manchurian plague was vanquished in four months, and his invention continues to keep us safe now. Masked Hero , written by Dr. Wu Lien-teh’s great-granddaughter Shan Woo Liu and charmingly illustrated by Lisa Wee, celebrates the little-known history of the N95 mask and the hero who first devised it. Back matter, including an author’s note and a time line, sheds further light on the ever-relevant past, encouraging budding scientists to think bravely—and remember the small acts we all can perform to keep our communities safe.","forthcoming":false,"isbn13":"9781536238327","publication_date":"20241015","publisher":"Candlewick Press","slug":"masked-hero","subtitle":"How Wu Lien-teh Invented the Mask That Ended an Epidemic","title":"Masked Hero"},"discovery":{"categories":{"all":[{"bisac_code":"JNF024020","confidence_band":"medium","label":"Illness & Injury","score":0.7245,"source":"bisac_hint_model"},{"bisac_code":"MED022090","confidence_band":"medium","label":"Infectious Diseases","score":0.697,"source":"bisac_hint_model"},{"bisac_code":"HEA039040","confidence_band":"medium","label":"Contagious Diseases","score":0.6954,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"JNF024020","confidence_band":"medium","label":"Illness & Injury","score":0.7245,"source":"bisac_hint_model"},{"bisac_code":"MED022090","confidence_band":"medium","label":"Infectious Diseases","score":0.697,"source":"bisac_hint_model"},{"bisac_code":"HEA039040","confidence_band":"medium","label":"Contagious Diseases","score":0.6954,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"JNF007090","confidence_band":"high","label":"Science & Tech Biographies for Kids","score":1,"source":"onix_publisher_code"},{"bisac_code":"JNF024020","confidence_band":"high","label":"Illness & Injury","score":1,"source":"onix_publisher_code"},{"bisac_code":"JNF061010","confidence_band":"high","label":"Inventions","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Illness & Injury","score":0.7245,"slug":"illness-injury"},{"label":"Infectious Diseases","score":0.697,"slug":"infectious-diseases"},{"label":"Contagious Diseases","score":0.6954,"slug":"contagious-diseases"}],"reader_fit":["Budding scientists interested in the history of the N95 mask"],"related_lists":[],"series":null,"similar_books":[{"authors":["Marilee Peters"],"book_id":"9781773215167","cover_image_url":"https://img.bookfrontier.com/9781773215167.jpg?v=01436dd5480104f4","score":0.6861,"title":"Patient Zero","url":"https://bookfrontier.com/books/9781773215167"},{"authors":["Gail Jarrow"],"book_id":"9781620917381","cover_image_url":"https://img.bookfrontier.com/9781620917381.jpg?v=98f57900d577c767","score":0.6816,"title":"Bubonic Panic","url":"https://bookfrontier.com/books/9781620917381"},{"authors":["Margaret Rae","Brian Nathanson"],"book_id":"9781524886455","cover_image_url":"https://img.bookfrontier.com/9781524886455.jpg?v=03bdc9e678bcc1f9","score":0.6495,"title":"Masks","url":"https://bookfrontier.com/books/9781524886455"},{"authors":["Lindsey Fitzharris","Adrian Teal"],"book_id":"9781547606030","cover_image_url":"https://img.bookfrontier.com/9781547606030.jpg?v=b598f85473a89367","score":0.6492,"title":"Plague-busters!","url":"https://bookfrontier.com/books/9781547606030"},{"authors":["Michael Lewis"],"book_id":"9780393881554","cover_image_url":"https://img.bookfrontier.com/9780393881554.jpg?v=6be7d0b2f2dc2c70","score":0.6431,"title":"The Premonition","url":"https://bookfrontier.com/books/9780393881554"},{"authors":["Deborah Hopkinson"],"book_id":"9781338360226","cover_image_url":"https://img.bookfrontier.com/9781338360226.jpg?v=5c80240857127444","score":0.6395,"title":"The Deadliest Diseases Then and Now (the Deadliest #1, Scholastic Focus)","url":"https://bookfrontier.com/books/9781338360226"},{"authors":["Roberta Edwards"],"book_id":"9780593383650","cover_image_url":"https://img.bookfrontier.com/9780593383650.jpg?v=e78fc0b15bcb8e02","score":0.6374,"title":"What Was the Plague?","url":"https://bookfrontier.com/books/9780593383650"}],"topics":[{"evidence_refs":["keyword:biographies for kids ages 6-8"],"label":"Kids","score":1,"slug":"kids"},{"evidence_refs":["keyword:biographies for kids ages 6-8"],"label":"Ages","score":0.2642,"slug":"ages"},{"evidence_refs":["keyword:biographies for kids ages 6-8"],"label":"Biographies","score":0.0616,"slug":"biographies"},{"evidence_refs":["keyword:asian"],"label":"Asian","score":0.0266,"slug":"asian"}],"what_you_get":["Themes: Epidemic response and public health, Discrimination and perseverance, Community safety.","Themes: Kids, Ages, Biographies.","Reading lane: Illness & Injury and Infectious Diseases."]},"llm_signals":{"confidence":0.91,"pacing":"unknown","reader_fit":["Budding scientists interested in the history of the N95 mask"],"themes":["Epidemic response and public health","Discrimination and perseverance","Community safety"],"tropes":[]},"source_presence":{"amazon":true,"book_detail":true,"goodreads":true,"llm_signals":true,"similarity_seed":true},"stats":{"amazon_ratings_count":19,"goodreads_ratings_count":72,"goodreads_reviews_count":16,"quality_score":0.8753}}
