Symptoms
Compare
Hyperdontia
The teeth in the Infected grow and can protrude from the mouth. Increases infectivity.

Hyperosmia
Thinning of the nasal epithelium significantly heightens zombie sense of smell. Increases severity

Hypocoagulability
Hypocoagulability is one of the symptoms presented in the branch of traits affecting the blood system in both Simian Flu and Shadow Plague. It causes significantly reduced ability of the blood to clot, which makes many patients bleed out. It will often cause death through exsanguination.

Hypotension
Low blood pressure deprives organs of oxygen and nutrients, increasing severity and causing profound fatigue.

Immaturity
Hormone production altered which causes reduction in maturity. Lower levels of hygiene increase infection. (Neurax Worm) Reduction in hormone levels causes immature and antisocial behaviour, reducing cure research. Lower levels of hygiene cause infection. (Frozen Virus)

Immune Support
Supports the immune system to make it harder for other diseases to kill people that you infect.
Immune Suppression
Pathogens attach to lymphocytes, suppressing immune system and allowing significantly greater freedom of mutation. Can be lethal

Indulgence
Leptin blockers causes hosts to lose self-control and do all sorts of things they wouldn't normally do. Increases infectivity
Inflammation
Inflammation obstructs bodily processes. Swelling can obstruct breathing and be fatal
Insanity
Neuropathic action of the pathogen in the frontal cortex causes severe emotional and behavioural abnormalities. Significantly harder to cure
Insomnia
Inability to sleep makes people irritable and less productive
Internal Haemorrhaging
Arterial membranes break down, causing rapid internal bleeding and death

Internal Haemorrhaging (Shadow Plague)
Arterial membranes break down, causing rapid bleeding and death

Intoxication
Opioid adjustments encourage overindulgence, as well as saying silly things. Increases infectivity but reduces happiness due to hangover

Jaundice
Accelerated viral reproduction in the liver results in bilirubin build-up, causing yellowing of skin, eyes and mucus membranes. Increases infectivity

Jealousy
Tendrils mesh with frontal cortex, causing feelings of dissatisfaction with life and constant comparisons with others. Significantly reduces happiness

Joint Pain
Inflammation in the joints causes pain when moving. Decreases chance of infection due to reduced movement.

Joy
Endorphin surge fills host with contentment and happiness, making them run around singing. Significantly increases infectivity

Jugular Bite
The infected feel an urge to go and bite others on the neck, specifically targeting the jugular. Increases infectivity

Latent Adaptation
Pathogen repeatedly alters the proteins of its cell wall helping to prevent an immune reaction. Significantly harder to cure.

Laughter
Hormone adjustments trigger joke-telling. Increases infectivity.

Love
Oxytocin stimulation emphasises feelings of love when around family and friends. Significantly increases infectivity and happiness.

Lumbrical Hypertrophy
Significantly strengthens zombie grip making it nearly impossible for prey to break free. Severity significantly increased.

Malignant Ascites
Accumulation of fluid in abdominal cavity due to severe cirrhosis. Can be lethal
