Smallpox eradication. Destruction of variola virus stocks.
1. The global eradication of smallpox was confirmed in 1980 (resolution WHA33.3). From 1981 to 1986, WHO undertook a programme to implement the post-eradication policies contained in the 1979 report of the Global Commission for the Certification of Smallpox Eradication and endorsed by the Health Assembly in resolution WHA33.4. Progress was reviewed year by year from 1981 to 1984 by the WHO Comm...

متن کاملSmallpox Vaccination of Laboratory Workers at US Variola Testing Sites
To evaluate the need to revaccinate laboratory workers against smallpox, we assessed regular revaccination at the US Laboratory Response Network's variola testing sites by examining barriers to revaccination and the potential for persistence of immunity. Our data do not provide evidence to suggest prolonging the recommended interval for revaccination.
متن کامل120 The Infectious Dose of Variola ( Smallpox ) Virus
Quantitative estimation of an individual's risk of infection due to airborne pathogens requires knowledge of the pathogen's infectious dose, in addition to estimates of the pathogen's airborne concentration and the person's exposure duration. Based on our review of the published literature on poxvirus infection, we conclude that the infectious dose of variola (smallpox) virus is likely one viru...
متن کاملOn the origin of smallpox: correlating variola phylogenics with historical smallpox records.
Human disease likely attributable to variola virus (VARV), the etiologic agent of smallpox, has been reported in human populations for >2,000 years. VARV is unique among orthopoxviruses in that it is an exclusively human pathogen. Because VARV has a large, slowly evolving DNA genome, we were able to construct a robust phylogeny of VARV by analyzing concatenated single nucleotide polymorphisms (...
