Smallpox From The Past

An anonymous reader submits "Earlier this year, librarian Susanne Caro was looking through an 1888 book on United States Civil War medicine and discovered a small envelope labeled 'scabs from vaccination of W.B. Yarrington's children' and signed by Dr. W.D. Kelly, the author of the book. After a bit of research, she realized they might be smallpox scabs used in early live vaccination methods and contacted various officials including the Centers for Disease Control and Prevention. The CDC was excited by the find, because it gives them an untreated specimen from over a century ago, and a chance to look at the disease's evolution. Although the FBI had concerns that the smallpox may have been planted in the book, most of the researchers believe the scabs are too old to be dangerous, and they fear they may not even be able to yield live smallpox."

      a bioweapons attack (resulting in numerous
      deaths, and the shut down of the U.S. Senate
      offices), it become popular for people to
      "copy cat" the weapon. Soon, people were
      sending packets of white talc power in the
      mail with threatening notes, all in hopes of
      causing a panic and shutting down a business
      for a few days.

      As we've gotten used to this sort of ruse,
      and developed technologies to detect anthrax
      spores, the people trying to spread panic have
      gotten more clever.

      Consider, for example, how hard it would be to
      create panic by sending a note through the mail
      claiming that the envelope contained small
      pox. Since small pox is tightly controlled,
      and highly infectious, it's unlikely a group
      (other than a government) has a sample of the
      virus. So the hoax would quickly unravel.

      A clever person who wanted to create a plausible
      story about how a small pox virus came to be
      found in a public space might have to work
      harder. For example, they could make up a
      story about old medical samples, museum equipment,
      etc.

      And so in this case, it's entirely reasonable
      for the FBI to question the origin of this
      envelope. No, I don't think they started
      out by saying "This was planted by Al Queda."
      Instead, they started with a skeptical
      line of questions: who had the book? was it
      ever check out before? where was it kept?
      who had access to this text? is the person
      claiming to make the find a real librarian?
      etc.

      I think in this case, you, my friend, are the
      one who jumped to conclusions about the
      conduct of the FBI. Indeed, it would seem

Hence there could be samples, possibly not even labelled or known to the owners, in a number of places in the world.

      Of all the changes I proposed, dropping the Electoral College is the most "radical", as in the dictionary definition "going to the root". The difference between a republic and a democracy, at least according to Plato, is the difference betwen the people setting the laws directly, and the people setting representatives who set the laws for them. Analogous to a value, and a pointer to a value. Or a libertarian society out of Heinlein's _The Moon is a Harsh Mistress_, with exclusively citizen's arrests, and immediate trials by a jury of witnesses and bystanders, versus selected representatives to do the work of government on behalf of the people, who periodically select those representatives.

      The Electoral College, though, is more like a "handle", a pointer to a pointer (to a value). The people elect Electors, who elect representatives, who elect laws. This design pattern is great for large populations of interchangeable sets of values, within which one repeatedly selects a specific value. Fast, repeated switching, along with clear semantics for the two layers of indirection are requirements for which handles are appropriate. They're also appropriate for very large populations of values, too large in number to address by the limited precision of a simple pointer. Memory spaces larger in magnitude than the bitwidth of the pointer are addressed this way, eg. >4GB RAM in a 32bit pointer to a character. Both of these applications of handles are workarounds for limitations of the addressing scheme. They work well, but when the limitations don't exist, they're unnecessary overkill, confusing, and prone to error, especially when writing new software that doesn't reflect the double-indirection of the handle.

      For the first hundred years or so of the American republic, a handle solved the problem of managing the communication of the large (1-10M+) population. Any timely consensus was "fast" in an age of horses and sail, across half a continent. And breaking the population into manageable tiers of components was absolutely necessary in managing reliable communication using newspapers among the largely illiterate, public speeches among the largely rural, and bean counting boxes among a largely post-feudal population. It was a design decision to overcome problems of implementing a republic on a scale orders of magnitude larger than any experienced by Plato, or anywhere else. It was wise to start the implementation with overkill and scale back, rather than fail early due to an unmanageable complexity. But now it just gets in the way.

      Who can defend any of the elections where the electoral vote misrepresented the popular vote, especially the gamed 2000 presidential election? The Electoral College was a flawed design from the beginning, vulnerable to system gaming. For example, a current book called _Negro President_ analyzes Jefferson's 1801 ascension to the the presidency owing to his electoral victories in the South. His electoral votes were swelled by the 3/5 elector per person value of slaves (who couldn't vote); if only voters were counted, Jefferson would have merely been a brilliant writer and revolutionary. Whether that would have been as good for the country, especially in light of the Louisiana Purchase, is another debate. But the will of the people was subverted by Electoral College manipulation, and continues to be. We don't need it, and its dead weight is helping drag down our country - drop it now.

  26. Probably not smallpox virus anyway by KFW · · Score: 5, Interesting

    AIAAD (Actually, I am a doctor). In fact, my specialty is Infectious Diseases.

    By 1888 vaccination against smallpox using cowpox or vaccinia virus was a common practice, as opposed to "variolization" (inoculation with actual smallpox virus, aka variola virus), since the former was so much safer. This is touched on only briefly in the Washington Post article. So even if there is viable virus in the scab, it may not be smallpox. For reference see the first part of this chapter.

    If the virus is nothing but the DNA and a protein coating around it, why are the people wanting it to be live?

    Am I missing something? What am I missing?

    As a card-carrying virologist let me give you a run down on the information you're missing. If you don't consider the type of nucleic acid (RNA or DNA), there are two types of viruses that infect mammalian cells - enveloped and non-enveloped. Enveloped viruses (such as smallpox) have an outer lipid bilayer (the envelope) that is studded with glycoproteins that need to bind specific molecules on the surface of mammalian cells to permit fusion between the viral envelope and the cell membrane. Fusion allows the virus' nucleic acid to enter the cell. The viral envelope is very fragile, and breaks down rapidly when dried. When the envelope breaks down, it spills the contents of the virus out -- i.e. the nucleic acid, which in the absence of the envelope doesn't have a means to specifically enter a cell. This is one reason why wiping surfaces with 100% ethanol (a dehydrating agent) is quite effective against enveloped viruses like HIV.

    Even viruses that are not enveloped have protein coats that directly interact with cell surface molecules that act as receptors to mediate the entry of these viruses into cells. The proteins that make up these coats also denature (lose their proper shape) with time, although this is typically a slower process.

    Finally, how stable is the viral nucleic acid? Viral nucleic acids are typically not present as naked RNA or DNA, but in a complex of DNA or RNA with proteins that coat them. These coated nucleic acids are quite stable. Nucleic acid from DNA viruses (like smallpox) is likely to be more stable than nucleic acid from RNA viruses, and I'm guessing that they should be able to do phylogenetic studies on the strain of smallpox present in those scabs after amplifying recovered DNA by PCR.

    BTW, after many years of Slashdot lurking, a wee bit of horn tooting. My lab works on how the genome of EBV latches on to human chromosomes. Here's a pretty picture from our work that was on the cover of the Journal of Virology last month.
