Combating viruses of Body and Mind.


September 12th  Issue of Nature carries two interesting  reports. First one is a feature article  on how  Democratic Republic of Congo (DRC)  is reeling under the burden of ebola virus.  The second one is a scientific analysis of the dynamics of online hate activity. These two reports, from totally different domains  provide  valuable insights into how to contain a  mighty foe in real and virtual worlds.

Timely diagnosis and immediate medical care can contain ebola  outbreak to a very large extent;  yet the prevailing conditions in DRC posed  major obstacles.  Political instability, tribal rivalries, turf wars  and  armed uprisings  exasperated the health workers.  Illiterate communities were and still are ignorant of the danger they are in; they mistrust strangers, especially healthcare workers and the vaccines they bring along. In many cases, after first round of vaccination the recipients  can't be traced, hampering  follow up work  thus making the entire effort futile and perhaps even more dangerous. Hence the first step before the WHO

team  towards containing Ebola virus in DRC was to earn  trust. This necessitated the creation of a network of healthcare workers partnering with   community/religious leaders, survivors etc.  UNICEF official Beigebieder observes that when survivors recount their experience, community members sit up, listen and are convinced.  
Thus DRC has been successful in resisting the spread of ebola virus. According to the WHO website the 1000th survivor has safely returned home.  Indeed a success story.

Could we  similarly contain and  prevent the spread of hate in cyberspace?  Obstacles loom large even before we start. DRC is a country with well defined boundaries and government in place. The ebola virus and the victims are real, tangible, and there is a vaccine. In contrast  cyberspace is  a virtual reality without boundaries and everything that happens there shares the same characteristics.  Above all   in many countries strict privacy laws govern and protect  this virtual world.  

But that didn't deter Neil Johnson Professor of Physics at the George Washington University. He and his team set out to understand the seeding  and proliferation of hate networks in cyberspace; to be precise how clusters sprout and how they establish connectivity at multiple levels.   Banned clusters adopted multiple  mutation strategies to survive:  regroup into new avatars or migrate to new platforms  or even adopt a new language. Johnson et al cites the example of  KuKlux Klan, the White Supremacy Group generally abbreviated as KKK. When Ukrainian authorities banned the group, it reppeared elsewhere, with the name written in Cyrillic and English language detection algorithms couldn't  nab it. 

Johnson's team puts forward  different encounter methods which could be used singly or in combination without infringing upon privacy laws. Eliminate  smaller clusters totally or partially  that feed into a much larger node. With the support system wiped out the larger node will automatically shrivel away. Or set up rival groups  against hate groups so that the time and energy of the targeted hate group is wasted away.  Encourage dissent within hate groups thus disrupt their activities.  Are these doable? Well,   not everybody is in agreement with this strategy. 

TAILPIECE
And what physicians say about disease is applicable here: that at the beginning a disease is easy to cure but difficult to diagnose; but as time passes, not having been recognized or treated at the outset, it becomes easy to diagnose but difficult to cure. The same thing occurs in affairs of state; for by recognizing from afar the diseases that are spreading in the state (which is a gift given only to the prudent ruler), they can be cured quickly; but when, not having been recognized, they are not recognised and are left to grow to the extent that everyone recognizes them, there is no longer any cure.
