  Hi @naturalme,
  
  The word disease covers a lot of things from infections which are caused by microorganisms like bacteria to illness due to poisons or genetic illnesses which are caused by mutations in a persons DNA or less obvious illnesses such as cancer, the causes of which are often unclear.
  
  Thanks for a great question
