This brief article aims to interrogate some widely used concepts in framing the interactions between disease epidemics, food systems and nutrition, with a particular focus on the COVID-19 crisis. How should we conceptualize vulnerability in such situations – both with regard to viral exposure and to subsequent nutrition-relevant impacts of epidemics and responses (including lockdowns)? Is it possible to simultaneously pursue strategies aimed at strengthening resilience and driving transformation (‘building back better’)? What type of framing and conceptualization can help illuminate entry points and options for responding effectively to interacting crises? In addressing these questions, it’s important to re-visit lessons from past attempts to address the impacts of epidemics on food and nutrition security.

流行病和食品系统：什么是框架，什么是完成

这篇简短的文章旨在探讨一些广泛使用的概念，以构建疾病流行、粮食系统和营养之间的相互作用，特别关注 COVID-19 危机。我们应该如何将这种情况下的脆弱性概念化——无论是在病毒暴露方面，还是在随后的流行病和应对措施（包括封锁）的营养相关影响方面？是否可以同时推行旨在加强复原力和推动转型（“重建得更好”）的战略？什么样的框架和概念化有助于阐明有效应对相互作用危机的切入点和选项？在解决这些问题时，重要的是重新审视过去尝试解决流行病对粮食和营养安全的影响的经验教训。
