A summer outbreak of human metapneumovirus infection in a long-term-care facility.
Human metapneumovirus (hMPV), a recently discovered paramyxovirus, is thought to be primarily a winter-spring pathogen affecting young children with a clinical presentation similar to that of respiratory syncytial virus. In June-July 2006, a respiratory outbreak in a long-term-care facility was reported to the local health department and investigated. Surveillance identified 26 residents and 13 staff with acute respiratory illness; 8 residents (31%) developed radiographically confirmed pneumonia, and 2 (5%) were hospitalized. Five of 14 respiratory specimens were positive by polymerase chain reaction assay for hMPV; sequencing identified genotype A. In institutionalized elderly persons, hMPV may be an important cause of respiratory outbreaks year-round.
