In technical-mathematical epidemiology the first sense &#8212; individuals &#8212; dominates modeling, and there is some stochastic-process-based modeling to capture the second sense &#8212; events. \u00a0The modeling of superspread behavior has apparently not been attempted.<\/p>\n<p>I will discuss a new class of epidemic models that represent multiple spread rates in terms of discrete behavior classes, rather than in terms of compartments comprising individuals. The model is framed in terms of $D$ behavior classes, each with its own spread rate. The evolution equation is an integro-differential equation on the $D$-simplex. The model is capable of describing the &#8220;superspreader&#8221; phenomenon in terms of behavior-specific spread rates, as opposed to terms of individual infectivity. I will show the existence of SIR-like separable solutions and discuss their stability, and their relation to late-time evolution of the dynamical system. I will demonstrate the numeric properties of the model using a $D=3$ case featuring a &#8220;safe&#8221; behavior, a moderate-spread behavior, and a superspread behavior.<\/p>\n<div class=\"tribe-events-single-event-description tribe-events-content\">\n<p><em>Please note that the meeting URL for this event can be seen on the <a href=\"https:\/\/wordpress.cels.anl.gov\/cels-seminars\/event\/virtual-lans-seminar-12\/\">cels-seminars website<\/a>, which requires an Argonne login.<\/em><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Seminar Title: A Behavioral Multispread Epidemic Model Speaker: Carlo Graziani, ANL\/MCS Date\/Time: August 12, 2020 \/ 10:30 AM &#8211; 11:30 AM Location: see meeting URL on the\u00a0cels-seminars website\u00a0(requires Argonne login) Description: In qualitative epidemiological discussions, the term &#8220;superspreader&#8221; is used &hellip; <a href=\"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/event\/virtual-lans-seminar-2\/\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":43,"featured_media":0,"template":"","meta":{"_acf_changed":false,"_monsterinsights_skip_tracking":false,"_tribe_events_status":"","_tribe_events_status_reason":"","footnotes":"","_members_access_role":[],"_members_access_error":""},"tags":[],"tribe_events_cat":[2],"class_list":["post-2611","tribe_events","type-tribe_events","status-publish","hentry","tribe_events_cat-seminar","cat_seminar"],"acf":[],"_links":{"self":[{"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/tribe_events\/2611","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/tribe_events"}],"about":[{"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/types\/tribe_events"}],"author":[{"embeddable":true,"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/users\/43"}],"version-history":[{"count":3,"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/tribe_events\/2611\/revisions"}],"predecessor-version":[{"id":2614,"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/tribe_events\/2611\/revisions\/2614"}],"wp:attachment":[{"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/media?parent=2611"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/tags?post=2611"},{"taxonomy":"tribe_events_cat","embeddable":true,"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/tribe_events_cat?post=2611"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
