Human behaviour is central to transmission of SARS-Cov-2, the virus that causes COVID-19, and changing behaviour is crucial to preventing transmission in the absence of pharmaceutical interventions. Isolation and social distancing measures, including edicts to stay at home, have been brought into place across the globe to reduce transmission of the virus, but at a huge cost to individuals and society. In addition to these measures, we urgently need effective interventions to increase adherence to behaviours that individuals in communities can enact to protect themselves and others: use of tissues to catch expelled droplets from coughs or sneezes, use of face masks as appropriate, hand-washing on all occasions when required, disinfecting objects and surfaces, physical distancing, and not touching one's eyes, nose or mouth. There is an urgent need for direct evidence to inform development of such interventions, but it is possible to make a start by applying behavioural science methods and models.

应用行为改变原理以减少SARS-CoV-2传播。

人类行为是导致SARS-Cov-2（引起COVID-19的病毒）传播的关键，在没有药物干预的情况下，改变行为对防止传播至关重要。为了减少病毒的传播，全球已采取隔离和社会隔离措施，包括待在家中的法令，以减少病毒的传播，但对个人和社会造成了巨大的损失。除了这些措施之外，我们迫切需要有效的干预措施，以增加对社区中个体可以采取的保护自己和他人的行为的依从性：使用组织捕获咳嗽或打喷嚏排出的飞沫，适当使用口罩，洗手在所有需要的情况下，均应对物体和表面进行消毒，保持物理距离，并且不要触摸眼睛，鼻子或嘴巴。
