There are currently 96,559 candidates on the list awaiting a kidney transplant in the US, and over 1500 people on the waiting list in Australia. In major cities in the US, the average wait is five to ten years. In Australia, the average wait is over three years. For those on the list, there are meagre options to get off it. They could receive a kidney donation from a relative or a friend. Internationally, some have opted for a murkier route. In 2012, the World Health Organisation reported an influx of people taking "transplant tours" to countries such as China, Pakistan or India for often poorly regulated and illegal operations. (Currently, Iran is the only country where it is legal to sell your organs, but not to foreigners). The WHO estimated 10,000 operations involving "black market" organs per year.
