Weak evidence for strong pandemic interventions: a 2019 WHO warning for the current COVID-19 crisis

ABSTRACT

PurposeSocial distancing. Travel bans. Confinement. The purpose of this paper is to document that more than 50% of the world population is affected by World Health Organization (WHO) recommendations for the 2020 coronavirus crisis. The WHO admits that the evidence quality for the effectiveness of these recommendations is low or very low.Design/methodology/approachThis self-contradiction is confirmed by a WHO document published in October 2019 as well as supporting documentation from the European Centre for Disease Prevention and Control.FindingsThis viewpoint concludes that an obvious resolution of this self-contradiction would be to limit restrictions and interventions to those for whose effectiveness the WHO's document reported that there was at least moderate evidence.Originality/valueA shift of focus is suggested from discussions on the commensurability and social costs of anti-COVID-19 interventions to their actual effectiveness.
