Abstract
Andes virus (ANDV) is a high-consequence infectious disease with substantial mortality. On May 2, 2026, the World Health Organization reported a multinational ANDV outbreak, raising questions regarding risk of transmission to healthcare personnel (HCP). We performed a systematic review per PRISMA guidelines (PROSPERO:CRD420261283806) for studies describing healthcare-associated ANDV exposure or transmission events to HCP. Eight studies reporting on 7 events were included, describing a total of 17 healthcare-associated cases. Overall, 207 individuals were exposed, including 118 HCP, resulting in 8 infections and 4 deaths among HCP. Studies describing HCP infections reported none or inadequate personal protective equipment (PPE) use. Transmission of ANDV to HCP has been reported in the setting of delayed implementation of transmission-based precautions or breaches in infection control practice. Limitations in published exposure events highlight the need for standardized reporting of exposure events and outcomes as well as infection prevention measures implemented.
