Effect of delay in development of detectable antibodies on observed seroprevalence in cross-sectional surveys. Trend in the true prevalence of ever infection in the population versus the actually-observed seroprevalence factoring the 3 weeks average delay in the development of detectable antibodies [7, 8]. Two scenarios are presented, one for an R0 of 1.6 (an epidemic in presence of social and physical distancing interventions) and an R0 of 3.0 (natural course of the epidemic in absence of any social or physical distancing interventions)
