GII.4 detection rates worldwide among norovirus-positive children with sporadic acute gastroenteritis.

<p>Data were collected from 53 studies conducted in 31 different countries among children with sporadic acute gastroenteritis. Studies with samples collected after the year 2000 with sample collection done for a minimum of one year and based on genotyping of the capsid region are included. Due to lack of sufficient available data from Africa, studies conducted for less than one year have also been included for this region. The data shown are from a total of 6,283 genotyped samples from 28 different studies from Asia, 13 from Africa, five from South America, one from North America, and three each from Europe and Central America (<a href="http://www.plospathogens.org/article/info:doi/10.1371/journal.ppat.1005385#ppat.1005385.s001" target="_blank">S1 Table</a>). The number (n) in the figure represents the number of genotyped samples, while the duration of sample collection for each region is mentioned within the parentheses. GII.NT represent non-typeables. Broken lines represent approximate percentages of secretors in the population.</p
