Super-spreading social events for COVID-19 transmission: evidence from the investigation of six early clusters in Bahrain.

ABSTRACT:

Introduction

This study aimed to characterize six early clusters of COVID-19 and derive key transmission parameters from confirmed cases that were traced between April and June 2020 in Bahrain.

Methods

Pairs of "infector-infectee" allowed us to map the clusters and estimate the incubation period serial interval as the secondary attack rate. The chi-squared test, with a p-value computed using the Monte Carlo test, measured associations between categorical variables. Statistical analysis was performed using R software and the "data.tree, tidyverse" libraries.

Results

From 9 April to 27 June 2020, we investigated 596 individuals suspected of COVID-19, of whom 127 positive cases were confirmed by PCR and linked in six clusters. The mean age was 30.34 years (S.D. =
