  1. aThe incidence and percentage of RV genotypes A, B, and C in the population are an underestimate, since the genotype of only 73 (80%) of the 92 RV-positive samples could be determined.
  2. bThe percentage in all cases are referred to the total number of samples.
  3. cIn bold are the statistically significant differences.
