Fighting Cholera Via Satellite

  
Space-age technology helps combat an old disease 

Though we may often think of cholera as a disease of the past, virtually eradicated when John Snow famously linked an 1854 outbreak of the epidemic in London to an infected water well on Broad Street, it still poses a threat in almost every single developing country in the world.
