Suppression of pandemics and epidemics cannot rely solely on waiting for effective vaccines and/or medical treatment: we need plans to use, improve & evaluate effective behavioural, environmental, social and systems interventions (BESSI) to reduce viral transmission.

The BESSI Collaboration aim to provide information about planned and completed research into reducing SARS-CoV-2 transmission, and facilitate both novel and replication research.

Many types of research are needed; the scorecard focuses on trials as one snapshot of current research. Data derived from Epistomonikas L-OVE website using the procedure, education and social distancing question filters and COVID-19 population filter.



Given the Covid-19 pandemic is likely to be around to at least mid-2021 (potentially followed by seasonal outbreaks) - even if a vaccine or effective treatments are developed - it is imperative to address BESSI evidence gaps now and to develop longer-term research priorities and processes to improve evidence about BESSInterventions to prevent and manage future infectious disease outbreaks.

BESSI Research Strategy


We aim to foster research synthesis, prioritization, piloting, and field trials in collaboration with health organisations, policy makers, communities, and a range of researchers relevant to BESSI (so Figure below).


What is BESSI's aim? A 5 minute video explains:


We aim to provide public protocols of BESSI trials that may be used or adapted to help with replication and additional research.
