From Cabin Cleanup to Critical Care

A 45-year-old male presents to the emergency department with severe respiratory distress after developing symptoms of fever, chills, myalgias, and a nonproductive cough five days ago. The patient had recently returned from a hiking trip in Yellowstone National Park, where he cleaned a cabin that had rodent nests and droppings. Upon arrival, he is hypoxic and requires supplemental oxygen and intubation. His condition worsens, developing hypotension requiring vasopressor support. Laboratory findings reveal leukocytosis with immunoblasts, thrombocytopenia, and elevated lactate. The patient is diagnosed with Hantavirus cardiopulmonary syndrome (HCPS), a condition linked to rodent exposure, specifically to the inhalation of viral particles from infected rodent droppings. Treatment focuses on advanced airway management, fluid resuscitation, and close monitoring of hemodynamic status. The patient requires intensive care unit admission, and state and local health departments must be notified due to the public health implications of HCPS.
