Figure 2. Phylogenetic tree showing sequence analysis of human Metapneumovirus (HMPV). Isolates prefixed with L were obtained from GenBank and represent isolates from the Netherlands. Isolates prefixed with 00hL are from this study; the following number indicates strain designations throughout the season: a, sample from an adult; c, sample from a child (<15 years). Scale shown is proportional to number of nucleotide substitutions per site.
1 MZ and JS designed the study; DF and MZ organized the sampling. JS performed the polymerase chain reaction analysis and designed the sequencing strategy. IS collected clinical data. All authors contributed to the writing of the manuscript.
