Gorgas argued that by eliminating the presence of adult mosquitoes capable of spreading the disease, eradicating yellow fever could become a possibility. His guidelines advocated for major environmental and infrastructural changes including draining ponds and swamps, constructing public water systems; and the use of mosquito netting. Despite being published by the Government Printing Office, his guidelines emphasized the need to make this information accessible to all, even those outside the federal government, stating: \u00a0\u00a0<em>\u201c<\/em><em>I thought an account of the relations of mosquitoes to disease, given in simple terms, readily understood by those who are not doctors, might help people generally in making an attempt to get rid of mosquitoes, each man about his own house.\u201d<\/em><em>\u00a0<\/em><\/p>\n<p><strong>Film and Video in the <em>Politics of Yellow Fever<\/em> <\/strong><\/p>\n<p>During the 1940s\u20131960s, mosquito control continued to take priority when protecting the public from yellow fever.

The people in the Office of Malaria Control in War Areas, which evolved into the CDC, knew that mosquitoes were the vector for malaria and other diseases, and they knew of effective ways to suppress that vector.

He downplayed negative concerns about its use by referencing how much research had been done in support of its effectiveness and safety. Notably, much of that research was conducted by the chemical industry at the request of the U.S. Army.<\/p>\n<p>In 1962, ecologist Rachel Carson exposed the questionable integrity and bias in the chemical industry\u2019s data. Her independent research provided incontrovertible proof that DDT was harming wildlife and increasing the incidence of cancer and other diseases in humans. The publication of her landmark book, <em><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/nlmcatalog\/?term=12020630R\" target=\"_blank\" rel=\"noopener noreferrer\">Silent Spring<\/a><\/em>, helped raise crucial concerns within the federal government regarding the disastrous consequences of overusing insecticides. A decade later the Environmental Protection Agency (EPA) was established and drafted its first act to ban DDT nationwide. In the 19th century, public health officials mistakenly believed that polluted air and soil were the causes of yellow fever. Ironically, the anti-mosquito campaigns of the 20th century created real hazardous health conditions in the air and soil.<\/p>\n<p>Yellow fever and its threat to global health served, in many ways, as a catalyst for creating data through new forms of record-keeping. At a time when the concept of data science had not yet been fully articulated, the epidemic spurred the creation of data visualizations illustrating how the disease was spreading. And now, in the 21st century, new epidemics continue to prompt innovative uses of data to find sustainable and responsible ways of protecting communities. The history of yellow fever in the U.S. presents a fascinating case study of the evolution of knowledge, information, and data. More specifically, this case study shows us how throughout the history of medical research, people collected, shared, and analyzed data. This history serves as a lens through which we can think critically about data science today, as researchers from many different disciplines engage with it, and especially as it serves to advance the medical and public health enterprise.<\/p>\n<p><em>Explore the online exhibition <\/em><a href=\"https:\/\/www.nlm.nih.gov\/exhibition\/politicsofyellowfever\/index.html\">Politics of Yellow Fever in Alexander Hamilton’s America<\/a>.<\/p>\n<p><em>Tannaz Motevalli is a researcher and exhibition coordinator for the Exhibition Program in the History of Medicine Division at the National Library of Medicine.<\/em><\/p>\n<p><em>Sarah Eilers is the Manager of Historical Audiovisuals in the History of Medicine Division at the National Library of Medicine.<\/em><\/p>\n<p><em>Laura Hartman is Rare Book Cataloger in the History of Medicine Division at the National Library of Medicine.<\/em><\/p>\n<p><em>Erika Mills is outreach coordinator for the Exhibition Program in the History of Medicine Division at the National Library of Medicine.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>By Tannaz Motevalli, Sarah Eilers, Laura Hartman, and Erika Mills In the previous blog post \u201cData Science in Politics of<\/p>\n","protected":false},"author":57991628,"featured_media":16513,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_coblocks_attr":"","_coblocks_dimensions":"","_coblocks_responsive_height":"","_coblocks_accordion_ie_support":"","advanced_seo_description":"","jetpack_seo_html_title":"","jetpack_seo_noindex":false,"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":false,"jetpack_social_options":{"image_generator_settings":{"template":"highway","enabled":false},"version":2}},"categories":[12763,2029,1359464,347145303,76943049,2347],"tags":[411245,22379,229093,136219,678875792,546948],"class_list":["post-16485","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-collections","category-exhibitions","category-films-videos","category-rare-books-journals","category-revealing-data","category-series","tag-1700s","tag-data","tag-ddt","tag-epidemic","tag-politics-of-yellow-fever-in-alexander-hamiltons-america","tag-yellow-fever"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2019\/06\/hand-ditching-malaria-8800526a_feature.jpg?fit=900%2C401&ssl=1","jetpack_likes_enabled":true,"jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/p3xcDk-4hT","jetpack-related-posts":[],"amp_enabled":true,"_links":{"self":[{"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/posts\/16485","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/users\/57991628"}],"replies":[{"embeddable":true,"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/comments?post=16485"}],"version-history":[{"count":14,"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/posts\/16485\/revisions"}],"predecessor-version":[{"id":26699,"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/posts\/16485\/revisions\/26699"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/media\/16513"}],"wp:attachment":[{"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/media?parent=16485"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/categories?post=16485"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/tags?post=16485"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}} |
