Hantavirus Cardiopulmonary syndrome: Another Reason to Avoid Mice.

Hantavirus cardiopulmonary syndrome is a severe illness transmitted by rodent excretions. We describe a case of a 24-year-old man who presented to the emergency department with cough, shortness of breath, chills, myalgias, nausea, and diarrhea. Physical examination and laboratory analysis revealed signs of respiratory distress and thrombocytopenia. The trajectory of his illness led to acute respiratory distress syndrome (ARDS) and hemodynamic instability. Serum testing was positive for hantavirus IgM and IgG antibodies. The patient was managed with supportive care and improved. This case highlights the importance of considering hantavirus when managing patients who develop thrombocytopenia, ARDS, and hemodynamic instability in the appropriate clinical setting.
