Abstract
Andes virus (ANDV) is the only hantavirus transmitted between humans through close contact. We detected the genome and proteins of ANDV in breast milk cells from an infected mother in Chile who transmitted the virus to her child, suggesting gastrointestinal infection through breast milk as a route of ANDV person-to-person transmission.

Andes virus (ANDV) is the only hantavirus transmitted between humans through close contact
The diagnosis of ANDV infection was confirmed by real-time reverse transcription PCR for ANDV RNA in blood cells, as previously described [4]
ANDV RNA has previously been detected in bodily fluids other than blood, such as saliva, respiratory secretions, and urine [2]
Summary
Andes virus (ANDV) is the only hantavirus transmitted between humans through close contact. ANDV RNA can be detected in patients’ blood, respiratory secretions, saliva, gingival crevicular fluid, and urine [2]. We report epidemiologic and virologic analyses of a mother in Chile with ANDV infection and apparent transmission to her newborn. The newborn was hospitalized for observation at DOL 17; at that time, ANDV IgM testing was negative (Reagenta, https://www.reagena.com).
