Knowing the number of cases an epidemic is first function epidemiological surveillance. An important underreporting was observed in many places during wave COVID-19 pandemic. To estimate this outbreak Borriana (Valencia Community, Spain), “Falles” mass gathering events March 2020, a cross-sectional study performed June 2020 querying public health register. Logistic regression models were used. From total 468 symptomatic diagnosed by anti-SARS-CoV-2 serology, 36 reported (7.7%), thus 92.3% (95% Confidence Interval [CI] 89.5%-94.6%), 13 unreported for every case.
