Smallpox News and Research

RSS

Smallpox is a highly contagious disease caused by the variola virus, a member of the Orthopox virus family. It is one of the most devastating diseases known to humanity, with a mortality rate as high as 30%. In 1967, the World Health Organization embarked upon an intensified vaccination campaign to eliminate smallpox, which culminated in the successful eradication of the disease globally by 1980.

By the mid-1980s, there were only two known repositories of variola virus: the Institute of Virus Preparations in Russia, and the US CDC. The events in the US in September and October 2001 highlighted the risk that the variola virus might be used as an agent of bioterrorism. Governments around the world are taking precautionary measures to be ready to deal with a potential smallpox outbreak.

NEJM examines global disease eradication efforts

"Since the last case of naturally occurring smallpox, in 1977, there have been three major international conferences devoted to the concept of disease eradication," an article in the New England Journal of Medicine reports and includes "a brief review of five diseases selected for eradication or elimination that illustrate the potential benefits of such efforts and some of the challenges they pose."

West African human population genomes provide important clues about evolution of HIV

Human immunodeficiency virus (HIV) may have affected humans for much longer than is currently believed. Alfred Roca, an assistant professor in the College of Agricultural, Consumer and Environmental Sciences at the University of Illinois, thinks that the genomes of an isolated West African human population provide important clues about how the disease has evolved.

Washington Post examines Guinea worm eradication efforts

The Washington Post examines global efforts to eradicate Guinea worm disease, writing, "The parasitic infection which has sickened millions, mostly in Asia and Africa, is on the verge of being done in not by sophisticated medicine but by aggressive public health efforts in some of the poorest and most remote parts of the world."

Detect-to-Protect project to measure performance of new sensors for biological agents

The idea that disease and infection might be used as weapons is truly dreadful, but there is plenty of evidence showing that biological weapons have been around since ancient times. Bioterrorism, as it is dubbed, is nothing new, and although medicines have made the world a safer place against a myriad of old scourges both natural and manmade, it still remains all too easy today to uncork a nasty cloud of germs.

Study helps explain how large DNA viruses undergo rapid evolution

Scientists have discovered that poxviruses, which are responsible for smallpox and other diseases, can adapt to defeat different host antiviral defenses by quickly and temporarily producing multiple copies of a gene that helps the viruses to counter host immunity.

HIV would 'remain a threat' even if world achieved 'AIDS-free generation' by any definition

Lawrence Altman, former senior medical correspondent for the New York Times, writes in an opinion analysis in the newspaper that while there was much discussion about "ending the AIDS epidemic" and an "AIDS-free generation" at the XIX International AIDS Conference (AIDS 2012) last week in Washington, D.C., "[o]ne obstacle is a failure to clearly define the epidemic or what it means to have an AIDS-free generation."

Polio eradication: an interview with Dr. Kathleen O’Reilly

Polio is a disease caused by a virus and results in paralysis, usually in the legs, of those affected. The paralysis is irreversible. In some extreme cases the virus spreads to the nerve cells of the brain reducing breathing capacity and this rarer form can be fatal.

Researchers use clever screening methods to speed vaccine production

Infectious diseases-both old and new-continue to exact a devastating toll, causing some 13 million fatalities per year around the world. Vaccines remain the best line of defense against deadly pathogens and now Kathryn Sykes and Stephen Johnston, researchers at Arizona State University's Biodesign Institute, along with co-author Michael McGuire from the University of Texas Southwestern Medical Center are using clever functional screening methods to attempt to speed new vaccines into production that are both safer and more potent.

Genetically modified mosquitoes offer hope of malaria eradication amid growing drug resistance

"In recent weeks, the emergence on the Thai-Myanmar border of malaria strains resistant to artemisinin, a plant-derived drug, have led to pessimistic headlines and reminders of the setback caused by resistance to the drug chloroquine, which began in the 1950s," columnist and author Matt Ridley writes in the Wall Street Journal's "Mind & Matter," noting, "April 25 is World Malaria Day, designed to draw attention to the planet's biggest infectious killer."
