Variola virus

Variola este o boală contagioasă, de natură virotică.Variola a fost una dintre cele mai mari catastrofe ale omenirii, omorând și desfigurând un număr imens de oameni de-a lungul secolelor; numai în secolul al XX-lea au murit de variolă între 300 și 500 de milioane de oameni. Numai în 1967 s-au îmbolnăvit de variolă circa 15 milioane de oameni și au căzut victime acestei boli. Smallpox is a highly contagious and deadly disease caused by the variola virus. It was estimated to have infected 300 million people in the 20th Century before it became the only human infectious disease ever to be completely eradicated Thousands of years ago, variola virus (smallpox virus) emerged and began causing illness and deaths in human populations, with smallpox outbreaks occurring from time to time. Thanks to the success of vaccination, the last natural outbreak of smallpox in the United States occurred in 1949 Before smallpox was eradicated, it was a serious infectious disease caused by the variola virus. It was contagious—meaning, it spread from one person to another. People who had smallpox had a fever and a distinctive, progressive skin rash. Most people with smallpox recovered, but about 3 out of every 10 people with the disease died

  1. variola virus: [ vi´rus ] any member of a unique class of infectious agents, which were originally distinguished by their smallness (hence, they were described as filtrable because of their ability to pass through fine ceramic filters that blocked all cells, including bacteria) and their inability to replicate outside of and without.
  2. Variola virus. Variola virus (or variola major virus) is the virus that causes smallpox.The virus is one of the members of the poxvirus group (Family Poxviridae).The virus particle is brick shaped and contains a double strand of deoxyribonucleic acid.The variola virus is among the most dangerous of all the potential biological weapons
  3. Variola virus, which causes smallpox, is no longer found in nature in any part of the world but is still feared as a bioterrorism agent. There is no effective drug for smallpox, and the length of protection afforded by the existing smallpox vaccine (based on live, attenuated vaccinia virus) is uncertain

Variola (smallpox) este o boală acută și contagioasă cauzată de virusul variolic, un membru al genului Orthopoxvirus din familia Poxviridae.Virusologii consideră că a evoluat dintr-un poxvirus prezent la rozătoarele africane în urmă cu 10 milenii. Numele derivă din cuvântul latin pentru pată, datorită faptului că apar erupții sub formă de pete pe fața și corpul. Variola virus is the most complex of the orthopoxvirus genus, having many different strains(6,7).

Variola virus o Smallpox virus Il virus del vaiolo (in latino scientifico : Variola virus , in inglese : Smallpox virus ) era l'agente responsabile del vaiolo umano , ormai scomparso in natura; era una specie di virus a DNA della famiglia dei Poxviridae , sottofamiglia Chordopoxvirinae , genere Orthopoxvirus In this new climate, the IOM was once again tasked to consider scientific needs for live variola virus. The committee evaluated the scientific need for live variola virus in four areas: development of therapeutics, development of vaccines, genomic analysis, and discovery research

Orthopoxvirus is a genus of viruses in the family Poxviridae and subfamily Chordopoxvirinae.Vertebrates, including mammals and humans, and arthropods serve as natural hosts. Currently, 12 species are in this genus, including the type species Vaccinia virus.Diseases associated with this genus include smallpox, cowpox, horsepox, camelpox, and monkeypox. The most infamous member of the genus is. vari o lă sf [At: EPISCUPESCU, PRACTICA, 230/19 / P: ~ri-o~ / V: (îvr) ~le, variol s / Pl: ~le / E: lat variolae, variola, ger Variola, Variolae, fr variole] 1 Boală infecțioasă, contagioasă și epidemică, provocată de un virus, caracterizată prin apariția la suprafața pielii (și a mucoaselor) a numeroase pustule care, după ce se vindecă, lasă cicatrice definitive Si: (pop. 638277074: Variola virus: organism-specific: Integrated Microbial Genomes: Variola virus: taxonomy/phylogenetic: International Committee on Taxonomy of Viruses: CDC Smallpox Vaccine Recommendations: taxonomy/phylogenetic: NCBI taxonomy bookmarks: 2 records from this provider: dna/protein sequence: VirOligo Compilation Lab: Wikipedia: taxonomy.

Variola definition is - smallpox; also : its causative poxvirus (species Variola virus of the genus Orthopoxvirus) Vaccinia virus (VACV or VV) is a large, complex, enveloped virus belonging to the poxvirus family. It has a linear, double-stranded DNA genome approximately 190 kbp in length, which encodes approximately 250 genes.The dimensions of the virion are roughly 360 × 270 × 250 nm, with a mass of approximately 5-10 fg Although variola virus was eradicated by the World Health Organization vaccination program in the 1970s, the diagnosis of smallpox infection has attracted great interest in the context of a possible deliberate release of variola virus in bioterrorist attacks. Obviously, fast and reliable diagnostic tools are required to detect variola virus and to distinguish it from orthopoxviruses that have.

Variola minor was a less fatal type of smallpox. The Centers for Disease Control and Prevention (CDC) estimate that only 1 percent of those infected died. However, it was less common than variola.
