I looked up military acronyms RED = radiological exposure device. Don't know if that has anything to do with this. There is also red.org, creepy site that talks about AIDS and Covid19. Here's what they say "(RED) has its name because red is the color of emergency. Global emergencies — whether HIV or COVID-19 — tend to hit the most vulnerable populations the hardest. In light of the current COVID-19 threat, (RED) is working closely with the Global Fund to help protect (RED)-funded HIV/AIDS programs."
