A code of conduct for data on epidemics

As a long-term champion of open-access research data on pandemic viruses and a member of the Italian Parliament, I urge Brazil to hasten the reform of its current biosecurity legislation. This would enable sharing of vital Zika virus samples and information, as recently called for by the World Health Organization (see M.-P. Kieny et al . Nature 533 , 469; 2016 , and go.nature.com/1o4x3dp ).
