title: Dangerous Risk Group-4 (RG-4) emergent viruses
abstract: World Health Organization (WHO) Risk Group-4 (RG-4) pathogens are among the most dangerous of the emergent and re-emergent viruses. International health agencies, working in concert, bridge the gaps in health care for populations at risk for RG-4 viral pathogen exposure. RG-4 virus research incorporates Biodefense Program and Biosafety Laboratory (BSL)-4 technologies. RG-4 viruses include Arena-<i>viridae</i>, Filo-<i>viridae</i>, Flavi-<i>viridae</i>, Herpes-<i>viridae</i>, Nairo-<i>viridae</i>
