Just one example of this is the HAMMER facility at Hanford, WA, where DOE can train people to deal with all manner of disasters. https://hammer.hanford.gov/
Given the potential for a laboratory-originating virus to pose a significant threat to national security, the DOE may be interested in studying the origins of SARS-CoV-2 to better understand the risks associated with biosecurity and to inform its efforts to prevent and respond to biological threats.
Secondly, the DOE has collaborated with other agencies, such as the National Institutes of Health (NIH) and the Centers for Disease Control and Prevention (CDC), in conducting research related to COVID-19. The origins of SARS-CoV-2 are an important aspect of the COVID-19 pandemic and understanding its origins can inform public health responses and the development of treatments and vaccines.
Finally, the DOE has a stake in global scientific cooperation and the international research community. The origins of SARS-CoV-2 are an area of intense global interest, and understanding the virus's origins is important for future pandemic prevention efforts. By contributing to the scientific understanding of the virus's origins, the DOE can help to advance international collaboration and cooperation in addressing global health threats.
