Everyone assumes that some responsible authority must be managing and coordinating information, but this may not be the case.49 Data sharing may also be hampered by policies for data privacy and data protection. Otherwise any sharing is likely to be ad hoc and sporadic based on personal relationships and informal networks.50 Many countries have addressed this delicate policy balance through ministerial or parliamentary directives that override existing policies during emergencies. Or they may allow for exceptions where, under certain conditions, one policy takes precedence over another. Such policies can be broad, at the national and regional levels, or they can be specific or bilateral, between agencies and line ministries.
