Introduction:
Norovirus GII.4 is the leading cause of outbreaks of acute and sporadic acute gastroenteritis worldwide. Information on the prevalence of norovirus in Portugal is scarce or null.
Methodology:
We used a GII.4 norovirus virus-like particle-based enzyme immune assay to measure the seropositivity rate of GII.4 norovirus.
Results:
A total of 342 (70%) out of 473 serum samples tested positive for anti-GII.4 norovirus IgG. No statistically significant differences were found between regions, sex and age groups.
Conclusion:
Norovirus GII.4 infections are frequent in Portugal.
