Insights
Human metapneumovirus (hMPV) significantly impacts young children, causing respiratory infections. The study found the highest incidence in children under two, highlighting its community effect.
Area of Science:
- Pediatrics
- Virology
- Epidemiology
Background:
- Human metapneumovirus (hMPV) is a known cause of severe respiratory illness in hospitalized children.
- Limited data exists on hMPV's community incidence and impact across different age groups.
Purpose of the Study:
- To evaluate the age-related incidence and community effect of hMPV infections.
- To determine the proportion of respiratory infections attributed to hMPV in children.
Main Methods:
- A cohort of 1,338 children under 13 years was monitored during one respiratory season in Finland.
- Nasal swabs were collected for viral detection upon any sign of respiratory infection.
Main Results:
- hMPV was detected in 3.5% of children, with the highest incidence (7.6%) in those under 2 years.
- hMPV accounted for 1.7% of all infections in children under 2 and peaked at 7.1% of all respiratory infections.
- 61% of hMPV-infected children under 3 developed acute otitis media.
Conclusions:
- hMPV has a significant community impact, particularly affecting children under 2 years.
- The findings underscore the importance of considering hMPV in pediatric respiratory infections, especially in young children.
- hMPV infection is associated with a high rate of acute otitis media in young children.
Abstract:
Human metapneumovirus (hMPV) is an important cause of lower respiratory tract infections in hospitalized children, but the age-related incidence and effect of hMPV in unselected children in the community have not been evaluated. We studied a cohort of 1,338 children <13 years of age throughout 1 respiratory season in Finland during 2000-2001. We examined children and obtained a nasal swab for viral detection at any sign of respiratory infection. hMPV was detected in 47 (3.5%) of the 1,338 children. The age-related incidence of hMPV infection was highest (7.6%) in children <2 years of age, in whom hMPV accounted for 1.7% of all infections during the season. During the epidemic peak, hMPV caused 7.1% of all respiratory infections in the cohort. Acute otitis media developed in 61% of hMPV-infected children <3 years of age. Our findings demonstrate that the effect of hMPV in the community is greatest in children <2 years of age.
