Today, AI technologies and tools play a key role in every aspect of the COVID-19 crisis response. To help facilitate the use of AI throughout the crisis, policy makers should encourage the sharing of medical, molecular, and scientific datasets and models on collaborative platforms to help AI researchers build effective tools for the medical community, and should ensure that researchers have access to the necessary computing capacity. To realise the full promise of AI to combat COVID-19, policy makers must ensure that AI systems are trustworthy and aligned with the OECD AI Principles.
