Relative predominance between genetic variants of norovirus, sapovirus and rotavirus among children with gastroenteritis at hospital and community settings in Nicaragua, 2009–2010.

aFisher's exact test with unadjusted odds ratio. Relative frequencies of genetic variants in hospital vs community setting. Mixed and non-typed infections were excluded from analysis.bOnly GII.4-2006 Minerva (n = 35) and GII.4-2009 New Orleans (n = 10) genetics variants were detected among GII.4.cGII.6 (n = 3), GII.14 (n = 3) and GII.9 (n = 1).dGI:GII (n = 3), GI:GIV (n = 1) and GI:GV(n = 1).eNot applicable.

a. 采用未校正比值比的费希尔精确检验（Fisher's exact test），比较医院与社区环境中遗传变异株的相对频率，本分析排除了混合感染及未分型感染病例。
b. 在GII.4型变异体中，仅检出GII.4-2006 Minerva（n=35）与GII.4-2009 New Orleans两种遗传变异株。
c. 检出GII.6型3例、GII.14型3例及GII.9型1例。
d. 检出GI:GII型3例、GI:GIV型1例及GI:GV型1例。
e. 不适用。
