Human Parainfluenza Virus in Homeless Shelters before and during the COVID-19 Pandemic, Washington, USA

Abstract

To determine the epidemiology of human parainfluenza virus in homeless shelters during the COVID-19 pandemic, we analyzed data and sequences from respiratory specimens collected in 23 shelters in Washington, USA, during 2019-2021. Two clusters in children were genetically similar by shelter of origin. Shelter-specific interventions are needed to reduce these infections.

Keywords: COVID-19; HPIV; King County; SARS-CoV-2; United States; Washington; coronavirus disease; epidemiology; homeless shelters; human parainfluenza virus; respiratory infections; severe acute respiratory syndrome coronavirus 2; viruses; zoonoses.
