Blood Fever:  Blood fever is a common disease, most often infecting soldiers, garbage handlers, and corpsehandlers.  It commonly lies dormant in piles of offal until it can enter the body through any open, bleeding wound.  It gains a foothold rapidly, causing the skin of the infected person to erupt in hundreds of small sores which bleed constantly.  This is accompanied by a high fever, stiff joints, sore muscles, a pounding heart, and accelerated breathing.

If left untreated, victims will bleed to death in a week.  The elderly and the overly obese often die not from the wounds but from heart failure caused by the increase in blood pressure and heart rate.  Treatment is bedrest, bandaging, and high food intake.  Some herbal remedies, especially those which calm the nerves and steady heart rate and breathing, are effective against blood fever.  Even after the victim has recovered, he is often covered in small scars which mark where the sores were.

Once a person has contracted and survived blood fever, they are generally immune to it from then on.  Those who are infected a second time (a phenomena which only occurs in 1 out of every 50 cases) usually shake the disease off within two or three days and are absolutely immune after that.

For some unknown reason, Lemenari are immune to this disease.

Crimson Fever:  Crimson fever is a rare but serious disease.  It is most often transmitted by insect bite (usually mosquitos), and is only found in the warmer lands that circle the Sea of Horses.  Crimson fever often lies dormant in the body for many weeks before the first symptoms. During this incubation period, the host is not contagious. Once the disease has become active, an infected person will develop a severe, itchy rash which will cover the entire body within a few hours. This is the first warning sign of the disease, and is where the disease gets its name.

Within a day of the development of the rash, the victim will suffer sharp stomach pains, and will vomit and suffer attacks of diarrhea continuously until he simply has nothing left to expel. During the contagious phase of the disease, the victim is unable to ingest anything other than water. Most crimson fever victims survive, though with great loss of weight; those that do die generally expire because of starvation.

As with many other illnesses, once a person has been infected with the crimson fever, they have a high resistance to subsequent infection.

Mageloss:  This rare affliction affects only mages and usually only the most powerful sorcerers who have been casting mighty magicks for many years. Decades of spell casting wears on the human (and non-human) nervous system. In some cases, such wear eventually results in the deterioration of the synaptic pathways in the brain and the nerves throughout the body. Only a handful of the most powerful wizards have ever been afflicted with this rare malady.

Mageloss typically takes 5 to 10 years to run its course, getting progressively worse with each passing year. Initial symptoms include shaking hands and forgetfulness. As the condition worsens, the victim will begin to experience a loss of short term memory and mild hallucinations. In the final years before the disease kills the mage, the condition is marked by tremors, excitability and senility. The most serious effect, however, is the detrimental affect this malady has on spell casting. As they synapses of the brain break down, the victim will experience increasing difficulty in correctly casting spells. This first affects only powerful magic, but soon begins to affect even minor spells.

Mageloss is a terrible and undignified way for a great wizard to end his career.  Often the truth is concealed by the wizard's apprentices even as they search for a cure.  One wizard, an official in the Soravian Royal Court named Vibius Artorius Fado is said to have committed suicide rather than endure such an end.  At present, there is no known cure, magical or otherwise.

Zombie Fever:  Zombie fever is marked by extreme weight loss, excessive vomiting, loss of appetite, weakness, hypersensitivity to light, and loss of skin pigmentation. It strikes suddenly and runs its course in two to three weeks. A person suffering from this illness often takes on a pale, gaunt appearance that can be mistaken for that of an undead creature, hence its name. It is caused by a bacteria that inhabits rotting wood. Victims often contract this disease in subterranean places, such as catacombs and crypts.  Once the disease has run its course, the victim will slowly return to their normal appearance over a week.
