Genome-wide comparison of cowpox viruses reveals a new clade related to variola virus
Cowpox virus, a cousin of variola virus
, causes a mild smallpox-like disease in cows.
There was no evidence on any remains that would suggest a smallpox infection, so the presence of variola virus
was very surprising," said Ana Duggan, a biologist from McMaster University who worked with Piombino-Mascali.
Mishra, Director, NIV, Pune, participated in the XI Meeting of the WHO Advisory Committee on Variola Virus
Research at Geneva (November 4-5, 2009).
Upham Steadman in 'Smallpox and Climate in the American Southwest' discusses research conducted to 'determine the optimal climatic conditions that favour the persistence of Variola virus
outside of a host'.
The last case of naturally acquired smallpox disease, caused by the orthopoxvirus variola virus
(VARV), occurred in 1977, and the last laboratory-acquired case occurred in 1978.
Two known stocks of variola virus
exist: one at the CDC in Atlanta, Georgia, and the other in the former USSR.
Shuttleton has unfolded a fascinating and neglected story of the literary legacy of variola virus
Issues addressed at this WHA included strengthening pandemic influenza preparedness and response; infant and young child nutrition; HIV/AIDS; polio eradication; sickle-cell anaemia; smallpox eradication and the destruction of variola virus
stocks; prevention of avoidable blindness; international trade and health; tobacco control; and intellectual property rights.
Unlike vaccination, which utilised the cowpox virus, inoculation involved the deliberate infection of a susceptible individual with Variola virus
, usually through an incision on the hand.
A: Smallpox is a contagious and often-fatal disease caused by the variola virus
, a particle so tiny that roughly 1,000 linked together span the width of a human hair.
He delves chronologically into the WHO eradication program, into the details of the current controversy over whether or not the variola virus
should be completely destroyed, and he describes how the world could go about protecting itself from a smallpox release.
is known to exist in two repositories: one in Atlanta (at the Centers for Disease Control and Prevention) and a second in Moscow (at the Institute for Viral Preparations).
It is caused by the variola virus
and comes in two strains: the less severe variola minor and the more deadly variola major
is the etiological agent of smallpox infection.
