Abstract
Background
Pediatric hantavirus cardiopulmonary syndrome/hantavirus pulmonary syndrome (HCPS/HPS) is rare but can progress rapidly from a nonspecific febrile prodrome to respiratory failure, shock, and multiorgan dysfunction. Pediatric-specific evidence is limited, and a comprehensive map of the clinical literature is lacking.
Methods
We conducted a systematic scoping review per Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA-ScR) guidance (protocol registered at DOI:10.17605/OSF.IO/MZDN4). PubMed/MEDLINE, Embase, Scopus, Web of Science, and Cochrane CENTRAL were searched from inception to May 2026. Eligible reports described children or adolescents (age ≤18 years) with HCPS/HPS and extractable pediatric clinical data. Two reviewers independently screened records, assessed overlap, extracted data, and appraised reporting quality using Joanna Briggs Institute tools.
Results
Of 2208 database records, 20 reports were included in the core pediatric synthesis after removal of 976 duplicates and screening. Reports were concentrated in the Americas. Recurrent features included fever, gastrointestinal symptoms, myalgia, thrombocytopenia, hemoconcentration, pulmonary edema, respiratory failure, and shock. Severe cases required mechanical ventilation, vasoactive support, extracorporeal membrane oxygenation, and in some cases renal replacement therapy. Larger pediatric case series and surveillance-level reports reported mortality of approximately 33% to 37%. Evidence was predominantly case-based with variable reporting completeness.
Conclusions
Pediatric HCPS/HPS is rare but potentially rapidly fatal. Early suspicion in endemic regions or after rodent exposure, with prompt supportive critical care and timely consideration of advanced cardiopulmonary support, is central to management.
