Special report: Andes Hantavirus risk assessment

In this special EMS One-Stop update, Rob Lawrence is joined by returning guest Dr. Alex Isakov to break down the rapidly developing Andes Hantavirus outbreak linked to the expedition cruise ship MV Hondius. What began as a handful of unexplained respiratory illnesses aboard a South Atlantic voyage has evolved into an internationally monitored infectious disease event involving multiple countries, quarantine operations, public health investigations and the repatriation of exposed passengers to specialized containment facilities in the United States. | MORE: Hantavirus outbreak aboard cruise ship sends Americans to biocontainment quarantine units Dr. Isakov is professor of emergency medicine at Emory University School of Medicine and executive director of the Emory Office of Critical Event Preparedness and Response (CEPAR). He also serves as EMS lead for the National Emerging Special Pathogens Training and Education Center (NETEC), where he helps lead national preparedness efforts for high-consequence infectious diseases. In the episode, he explains how Andes Hantavirus differs from other hantaviruses already present in North America because it is capable of person-to-person transmission in limited circumstances. The discussion covers transmission dynamics, incubation periods, PPE recommendations, public health monitoring and why experts continue to assess the overall public risk as low. Listeners are also directed toward the excellent educational resource hub on preparedness and response available through NETEC Hantavirus Resources.
