Virus biosafety and biodefense category list comparison.

aSmallpox is caused by Variola viruses. Variola viruses including Variola major which causes disease with serious clinical symptoms and Variola minor (alastrim) which causes disease with less severe clinical symptoms. NIH laboratory biosafety categorization:, Variola major is not listed, but Variola, alastrim and whitepox are restricted to a single national facility (World Health Organization Collaborating Center for Smallpox Research, Centers for Disease Control and Prevention, Atlanta, Georgia); EU laboratory biosafety categorization: Variola major and Variola minor are in group 4; Chinese laboratory biosafety categorization: Variola virus and alastrim virus are in group 1.
bEU biodefense categorization: Congo-Crimean hamorrhagic fever virus is listed.
cNIH laboratory biosafety categorization: Junin virus candid #1 vaccine strain is in group 2.
dNIH laboratory biosafety categorization: Venezuelan equine encephalitis is in group 3, Venezuelan equine encephalitis vaccine strains TC-83 and V3526 are in group 2.
eNIH laboratory biosafety categorization: Influenza virus is in group 2, 1918H1N1, human H2N2 (1957–1968) and highly pathogenic avian influenza H5N1 strains are in group 3. EU biodefense categorization: lists influenza virus new strains.
fNIH laboratory biosafety categorization: Japanese encephalitis virus is in group 3, Japanese encephalitis virus vaccine strain SA 14-14-2 is in group 2. EU laboratory biosafety categorization: lists Japanese B encephalitis.
gNIH laboratory biosafety categorization: yellow fever virus vaccine strain 17D is in risk group 2. Chinese laboratory biosafety categorization: yellow fever virus is in group 1, yellow fever virus vaccine strain (17D) is in group 3.
