Named after an outbreak linked to laboratory workers exposed to infected green monkeys imported from Uganda.<\/li>\n<li><strong>Geographical spread: <\/strong>Most outbreaks have occurred in <strong>sub-Saharan Africa<\/strong>, including countries like <strong>Tanzania, Uganda, Angola, Ghana, Kenya, and Zimbabwe<\/strong>.<\/li>\n<li><strong>Transmission: <\/strong>Initially transmitted from <strong>fruit bats<\/strong> (<i>Rousettus aegyptiacus<\/i>) to humans. Spread occurs through <strong>direct contact<\/strong> with bodily fluids of infected individuals or contaminated surfaces.<\/li>\n<li><strong>Symptoms:<\/strong>\n<ul>\n<li><strong>Early signs<\/strong>: High fever, severe headache, and malaise.<\/li>\n<li><strong>Advanced stage<\/strong>: Severe bleeding, liver failure, multi-organ dysfunction, shock, and death within 8-9 days of symptom onset.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Fatality rate: <\/strong>The <strong>average case fatality rate<\/strong> is approximately <strong>50%<\/strong>, varying from <strong>24% to 88%<\/strong> depending on the virus strain and case management.<\/li>\n<li><strong>Diagnosis: <\/strong>Confirmed through <strong>RT-PCR (Reverse Transcription Polymerase Chain Reaction)<\/strong> tests and <strong>virus isolation<\/strong> procedures that require <strong>maximum biohazard containment<\/strong>.<\/li>\n<li><strong>Treatment:<\/strong> No specific treatment exists. Supportive care includes <strong>rehydration<\/strong>, <strong>electrolyte replacement<\/strong>, and <strong>symptom management<\/strong>, improving survival chances.<\/li>\n<li><strong>Vaccine development:<\/strong> Promising vaccines, such as the <strong>Sabin Vaccine Institute\u2019s single-dose vaccine<\/strong>, are under <strong>Phase 2 trials<\/strong> in Uganda and Kenya. Rwanda also received investigational vaccines to support outbreak control.<\/li>\n<\/ul>\n<p><strong>Key Facts About Rwanda:<\/strong><\/p>\n<ul>\n<li><strong>Geography:<\/strong> A <strong>landlocked country<\/strong> in East-Central Africa, referred to as the <strong>&#8220;Land of a Thousand Hills&#8221;<\/strong>.\n<ul>\n<li>Borders: <strong>Burundi, Tanzania, Uganda, and the Democratic Republic of the Congo<\/strong>.<\/li>\n<li>Rivers: The <strong>Nile<\/strong> and <strong>Congo<\/strong> rivers flow through Rwanda.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Capital City:<\/strong> Kigali.<\/li>\n<\/ul>\n<hr \/>\n<h3>Q1). What are the components of a virus?<\/h3>\n<p>A virus contains genetic material (DNA or RNA) inside a protein coat called the capsid. Some viruses have an outer envelope made of lipids and proteins.<\/p>\n<h3>Q2). How are viruses classified based on structure?<\/h3>\n<p>Based on structure, viruses are classified as helical, icosahedral, enveloped, and complex. Helical viruses have spiral capsids, and icosahedral has polygonal capsids.<\/p>\n<p><strong>Source: <\/strong><a href=\"https:\/\/www.downtoearth.org.in\/africa\/rwanda-declares-end-of-marburg-outbreak-who-africa\" target=\"_blank\" rel=\"noopener noreferrer nofollow\"><strong>DTE<\/strong><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>MVD is a severe and often fatal hemorrhagic fever caused by the Marburg virus, with no approved vaccines or treatments currently available.<\/p>\n","protected":false},"author":5,"featured_media":3419,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-3418","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-prelims-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/3418","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/comments?post=3418"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/3418\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/3419"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=3418"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=3418"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=3418"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
