Respiratory syncytial virus and human metapneumovirus in children with acute respiratory infections in Yemen.

ABSTRACT

A survey of 604 Yemeni children younger than 2 years with acute respiratory infections identified respiratory syncytial virus (RSV) in 244 (40%), human metapneumovirus (HMPV) in 41 (7%) and RSV/HMPV coinfection in 25 (4%) children. RSV infections occurred in younger children and were associated with more severe hypoxia than observed with HMPV. Both viruses are important causes of severe acute respiratory infection in Yemen.
