Abstract

We describe a case of hantavirus pulmonary syndrome in a patient exposed to Sin Nombre virus in a coastal county in California, USA, that had no previous record of human cases. Environmental evaluation coupled with genotypic analysis of virus isolates from the case-patient and locally trapped rodents identified the likely exposure location.

Highlights

We describe a case of hantavirus pulmonary syndrome in a patient exposed to Sin Nombre virus in a coastal county in California, USA, that had no previous record of human cases
We report a case of Hantavirus pulmonary syndrome (HPS) in a patient exposed to Sin Nombre virus (SNV) in a coastal county in California, USA, that had no previous record of human cases
We found that the SNV glycoprotein sequence from the case-patient was genetically related most closely to the hantavirus sequences recovered from the case-patient’s farm (Figure)

Summary

Introduction

We describe a case of hantavirus pulmonary syndrome in a patient exposed to Sin Nombre virus in a coastal county in California, USA, that had no previous record of human cases. We report a case of HPS in a patient exposed to SNV in a coastal county in California, USA, that had no previous record of human cases. Serum collected 4 days after illness onset tested negative at the local public health laboratory for influenza A and B.
