In Well's story "War of the Worlds", the alien invaders from the Planet Mars are stopped in their tracks by the lowliest of Earth's creatures. Concurrently, in Crichton's "The Andromeda Strain" the reverse is true...that the "alien" is an extremely deadly virus.
William Bramley wrote http://www.amazon.com/Gods-Eden-William-Bramley/dp/0380718073 an historical investigatory work dealing the prospect that germ warfare, of a sort, has been used against the people of this planet for centuries.
The Bible seems to relate similar actions.
The issue was re-kindled when the "Majestic Documents" began to be investigated, as there is mention of an alien virus there, as well. Of course I realize that most discount all of the documents as being created as a red herring, but the information had an effect, none-the-less.
What of it?
Has anyone ever conducted an epidimological study regarding any of those who think they have had contact with Non Terrestrial Entities? For instance, did Betty, and or Barney Hill become severely ill a day or two after the event, and simply not think anything of it?
Did Travis Walton fall ill later, and not make a connection?
Has anyone seen any patterns along these lines?
I don't have the time I used to, like I did when I was immersing myself in the UFO records, and alien virus articles of different sorts abound on the Internet, but I think this angle of the abduction phenomena and sickness would be interesting to cover more indepth.
