The rapid, open, and transparent sharing of data on this outbreak is now being threatened by rumours and misinformation around its origins.
We stand together to strongly condemn conspiracy theories suggesting that COVID-19 does not have a natural origin.
Conspiracy theories do nothing but create fear, rumours, and prejudice that jeopardise our global collaboration in the fight against this virus.
We support the call from the Director-General of WHO to promote scientific evidence and unity over misinformation and conjecture.
