Considered by some a curse from the gods to punish greed, and by others, a boon to provide much needed precious materials, the truth is that wherever this disease is found, chaos ensues.
Golden fever is caused by the gradual alchemical transmutation of the metals in a person's blood into gold, and eventually, all their tissues.
Unknown to everyone, this disease is caused by the bite of the golden-horned adder.
Those that survive the bite and venom of the golden-horned adder tend to assume that all side-effects are gone by the time the first symptoms of golden malaise start to appear. However, they are wrong; the venom has long-lasting effects. The first noticeable symptoms typically appear one to three months after the bite.
At first, the person will start feeling sluggish. This period is followed by a period of euphoria and high energy, which typically lasts a month. Afterwards, the affected person progressively starts losing energy, and their limbs start hardening. Typically, six months after showing the first symptoms, the person is bed-ridden, incapable of moving and having respiratory issues.
You know mom has been sick...
Folks say the gods have chosen to send us a gift, through her, but that means she has to leave us. We only have a few more months, so let's make the most of it. But afterwards... afterwards we will never be left needing no more.— Maxrii
The golden malaise has the capacity of causing chaos wherever it is found. People suspected to have this disease have been kidnapped (often wrongly), worshipped, and killed, amongst others.
All of this because once the person dies, their whole body becomes a solid block of gold within a day.
Depending on the community where the affected lives, people will seek to make their condition public or keep it hidden.

Geographic Spread
Golden malaise is typically restricted to the continent of Friac'seoue (which is, of course, where the golden-horned adder lives). However, there are records of a few cases outside of Friac'seoue.
These cases are either of people who were bitten in Friac'seoue or from imported snakes kept as exotic pets.
In the continent of Tiel, there is a famous statue of a person that suffered from golden malaise.
Tereli Zandiel was a rather rotund woman, part of a rich family that had no real need for that sort of money.
When she died of golden malaise, the family donated the "statue" to the city, under one condition. As long as the city continues to prosper, the statue will be prominently displayed to symbolise the city's success.
But should the city ever be in dire need, the statue could be used to make coins and ingots for trade.
I know I'm a terrible person, but I can totally see people trying to run a business on something like cutting of the infected limb and dropping it into a pool of blood. Very good take on mixing alchemy with disease. Were golden-horned adders can be found?
Uffff.... I had not even thought about that (re: limb and pools of blood)!
Golden-horned adders can be found on the continent of Friac'seoue, which is a continent in my world inspired in the African continent.
