Variola virus<\/strong>.<\/p>\n\n\n\n<p><strong>Explanation<\/strong>:<\/p>\n\n\n\n<p>Smallpox is a contagious and sometimes fatal disease caused by the <strong>Variola virus<\/strong>, a member of the <strong>Poxviridae family<\/strong>. The virus is characterized by fever, fatigue, and a distinctive skin rash, which progresses from flat red spots to pus-filled blisters, eventually scabbing over and leaving scars.<\/p>\n\n\n\n<p>Variola virus was declared eradicated in 1980 by the World Health Organization after a successful global vaccination campaign. This achievement marked the first disease ever eradicated by human effort. The <strong>Variola virus<\/strong> was the sole cause of smallpox, and the term &#8220;smallpox&#8221; was historically used to differentiate it from &#8220;chickenpox,&#8221; another viral condition caused by the varicella-zoster virus.<\/p>\n\n\n\n<p>To clarify the other options:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A. Molluscum contagiosum virus<\/strong>: This virus causes molluscum contagiosum, a skin infection characterized by small, raised, and smooth lesions. Though it belongs to the same family (Poxviridae), it is not associated with smallpox.<\/li>\n\n\n\n<li><strong>B. Vaccinia virus<\/strong>: This virus is closely related to the <strong>Variola virus<\/strong> but is primarily used in the smallpox vaccine. Vaccinia is not the cause of smallpox, but it plays a role in the immunization against it.<\/li>\n\n\n\n<li><strong>C. Mpox virus<\/strong>: Mpox (formerly known as monkeypox) is caused by a different virus, also from the <strong>Poxviridae family<\/strong>, but it is not the same as the <strong>Variola virus<\/strong>. Mpox typically causes less severe symptoms than smallpox, but the virus can cause rashes similar to those seen in smallpox.<\/li>\n\n\n\n<li><strong>E. Cowpox virus<\/strong>: This virus causes cowpox, primarily seen in animals like cows, and can occasionally be transmitted to humans. It is closely related to the <strong>Variola virus<\/strong>, but like vaccinia, it is not responsible for smallpox.<\/li>\n<\/ul>\n\n\n\n<p>Thus, the <strong>Variola virus<\/strong> is the true causative agent of smallpox.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following viruses is associated with smallpox?
