“COVID-19 has demonstrated that health inequities and disparities can no longer be tolerated. We must concern ourselves with the well-being of the world’s citizens, for an infectious disease anywhere can be an infectious disease everywhere.

COVID-19 also underscored the importance of timing when trying to contain the potential damage of an emerging or re-emerging infectious disease. The timely recognition of these threats is critical to preventing the next global pandemic.

GeoSentinel is poised to respond. Right now, we have an unparalleled network of clinicians, scientists and global health experts around the world capable of advanced disease recognition, diagnostics and therapeutics—all the elements needed for real-time surveillance and response.

The GeoSentinel Foundation aims to make sure this network has all the resources necessary to fulfill their critical mission.”
