Resumo
The objective of this study was to describe the circulation of caliciviruses in the West Central region of Brazil and
its correlation with children’s gender and age, as well as with the year and months of the sample collection. Reverse
transcriptase-polymerase chain reaction was performed to detect the human calicivirus genome in 1006 fecal
samples that were collected in Goiânia (n = 696) and Brasília (n = 310). Viral RNA was detected in 8.6% of the
samples. No significant difference in viral prevalence was found regarding gender, age or year of the sample.
However, it was observed that in Goiânia, there is a higher incidence of caliciviruses from September to March. The
analysis employing three primer pairs demonstrated that the Ni/E3 or JV12/13 primer pairs, which detect norovirus
(NoV), detected 41 positive samples while the 289/290 primer pair, which detects NoV or sapovirus, detected the
remaining 46 samples. Calicivirus circulates in the West Central region of Brazil and for better detection of this
virus it is important to use more than one primer pair. Also, we conclude that the seasonality presented by this virus
is related to higher humidity in the period.
