Diagnostic Considerations

Coinfection with human metapneumovirus (hMPV) and other viral respiratory pathogens has been documented in several studies, with the clinical significance in these situations unclear. [37, 38, 39, 40] RSV and hMPV coinfection was found in 70% of children with RSV infection who required intensive care in Liverpool, United Kingdom. [37] In addition, Semple et al showed that the rate of intensive care admissions and mechanical ventilation in patients coinfected with RSV and hMPV was greater than in infection with either pathogen alone. [39] However, other studies have not shown that coinfection plays a significant role in disease severity. [38, 41] Thus, further research is needed to definitively elucidate the clinical impact of coinfection.
