This course explores the link between security (national and international) and public health. Its primary target audience are students who may not have health security as a primary work responsibility in the future, but will need an understanding of how public health, biotechnology, emerging technologies like AI, and infectious diseases have national or international security implications. Students will gain an understanding of the impact disease has on security, and will have an opportunity to examine the policy, ethical, historical, and economic issues that surround biological sciences and security, including the development of medical countermeasures. Trends and advances in the biological sciences, their societal and health benefits, the potential threat of deliberate or accidental misuse, and preparations for a future pandemic will be explored. Students will gain an understanding of how past disease emergencies have intersected with national and international security from a US perspective, including COVID-19, Ebola (2014), and anthrax (2001), and ongoing US preparations for future health security events. While classes will be taught by Hopkins faculty, class sessions will also engage experts across the US Government, industry, and relevant policy organizations for lecture discussion and student interaction and networking.
