International collaboration through the sharing of health data is crucial for advancing human health. But it also comes with risks — risks that countries around the world seem increasingly unwilling to take.
On the one hand, the international sharing of health-related data sets has paved the way for important advances such as mapping the human genome, tracking global health outcomes, and fighting the rise of multidrug-resistant superbugs. On the other hand, it can pose serious risks for a nation’s citizens, including re-identification, exploitation of genetic vulnerabilities by foreign parties, and unauthorized data usage. As countries aim to strike a difficult balance between furthering research and protecting national interests, recent trends indicate a shift toward tighter controls that could chill international collaborations.
