Vector S01 - Ep. 4: The Cruise

Vector S01 - Ep. 4: The Cruise

Vector covers the MV Hondius outbreak, the first documented hantavirus cluster on a ship and the first major export of Andes virus from South America. We trace the ship's voyage from Ushuaia, the first death on April 11, the medical officer's call to shore, the international notification sequence that started on May 2, the virological reason this strain matters (it is the only hantavirus on earth known to spread person to person), the Argentinian investigation tracing the index case back to a bird-watching exposure, the repatriation of passengers across thirteen countries, and the 42-day quarantine of 16 American passengers at UNMC in Nebraska. We close by setting up the synthesis episode and the Moderna vaccine story that follows it. SHOW NOTES 1. WHO DON-601: Hantavirus cluster linked to cruise ship travel, Multi-country.

Vector S01 - Ep. 3: The Hackman Coincidence

Vector reports from Santa Fe, where Betsy Arakawa died of hantavirus pulmonary syndrome around February 12, 2025, and her husband Gene Hackman died eight days later of cardiovascular disease, with advanced Alzheimer's as a significant contributory factor. We walk through Arakawa's last days using her computer's search history and email records, the property's post-discovery environmental assessment, the clinical structure of HPS, and the question her death raised: how often does this disease go undiagnosed in the United States.

Vector S01 - Ep. 2: The Cabin in Mammoth Lakes

Vector reports from Mammoth Lakes, California, where three hantavirus deaths in a four-month span (February, March, and April 2025) have raised questions that the county's thirty-two-year history with the disease has not answered. We trace the cluster through Mono County Public Health statements, walk through the unusual exposure profile (two of three victims had no mice in their homes, but all three had mice in their workplaces), and pull up the 2012 Yosemite Curry Village precedent for what happens when seasonal architecture and deer mouse habitat overlap. We close with the climate question: a deer-mouse population boom in the Sierra echoes the conditions that triggered the original 1993 Four Corners outbreak. SHOW NOTES 1.
