Vampire Fever

Vampire Fever is a very rare occurrence. Like with normal fevers, Vampire fevers cause an increase in body temperature, which can be very deadly for a vampire as their body temperature is on the lower side. It can cause a vampire to become very aggressive and lose control. There are many theories suggest that Vampire Fever is a modern version of an episode of the disease called Porphyria that happens to vampires, as they carry the gene for the disease.


There is no main cause or explanation for Vampire Fever. Because it might be related to Porphyria, Vampire fever can be caused by some similar triggers, such as drugs that interact with the liver or too much exposure to sunlight.

At most times Vampire Fever does not leave any permanent damage or effects, but that doesn't mean it will never happen. If not treated fast enough Vampires can suffer from mental problems such a depression, confusion, anger issues, and other mental complications. Damage can also be done to the kidneys and liver. Breathing problems, chronic pain, seizures and scars are also a problem

Affected Groups

This disease is mostly found in children as they are more prone to illness and is mostly found in males but females are also affected.


There is no way to Prevent Vampire Fever


Vampire fever is possibly related to a disease called porphyria, a genetic liver disorder that causes a build-up of a substance called porphyrins. It is said that vampires are descendants of humans who had porphyria that died but came back to life. Theories suggest that Vampire Fever is an episode of Porphyria that happens to vampires as they do carry the gene for Porphyria.


Vampires are said to be normal people that carried the disease, Porphyria. When they died they didn't actually die, but transformed. Although Vampires have gradually evolved throughout the time they are still prone to having an episode of Porphyria, only this time it's a more modern, vampiric version.

Cultural Reception

Because Vampire fever is so rare, many other vampires do not know about it and will often make assumptions when another vampire gets the illness as they don't often get sick with Human illnesses like the flu. Some will think they're cursed and will actively avoid them as they are afraid of getting cursed.
