Description

This mod introduces a deeper and more realistic medical system, increasing survival immersion in DayZ. Each disease and injury progresses through distinct stages, with specific symptoms and treatments. It includes many medicines, tools and diagnostic methods: from basic bandaging up to more complex surgical procedures. To survive, you must carefully monitor your character's condition and act correctly to prevent infections and deterioration.

Core components

1. Prophylaxis and treatment: medicines, vaccines, disinfection.
2. Physical condition: hematomas, bullet wounds, melee wounds, internal organ injuries, surgical sutures, concussion, hemostasis, hematopoiesis.
3. Infections and diseases: cold/pneumonia, food poisoning, chemical poisoning, zombie virus, sepsis, rabies.
4. Sintomi: pain, overdose.
5. Emotional states: sleep, mental health.
6. Zones: psionic zone.

Prophylaxis and Treatment

MEDICINES

Medicines are divided into three categories: tablets, ampoules and injectors. Tablets are mainly used in early stages and for prevention; each pack contains ten tablets and matching packs can be combined. Ampoules contain stronger drugs for complex diseases or moderate-to-severe stages and require a syringe. After each injection, the syringe becomes contaminated and must be disinfected with alcohol or boiled in a pot of water over a fire. Injectors work similarly to ampoules but do not require a syringe because they are single-use.

VACCINES

Vaccines provide protection against the most dangerous diseases by significantly reducing infection risk. After administration, specific immunity develops: this helps the character avoid infections in contaminated environments. To maximize protection, vaccinate in advance and periodically check when a booster is needed.

DISINFECTION

Disinfection is mandatory to maintain sterility and prevent wound infections. Dirty medical tools must be disinfected before use to reduce contagion risk. Before medical or surgical procedures, it is also important to disinfect hands, especially in field conditions.

Physical Condition

HEMATOMAS

Hematomas can appear after zombie hits or blunt weapon trauma. If numerous, health starts to drop. They heal naturally over time, but ointments speed up recovery.

INTERNAL ORGAN, BULLET AND MELEE WOUNDS

The character can suffer puncture wounds (melee weapons) or bullet wounds (firearms), both potentially with heavy bleeding and immediate bandaging needs. Hemostatic bandages are more effective than regular bandages or rags. After bandaging, mild bleeding can remain until the foreign body is removed surgically. In severe cases, internal organ injuries may develop, deeper and harder to treat. Ballistic vests in good condition can reduce or block hits depending on caliber; if a hit is stopped, a non-penetrating injury can still remain as a hematoma.

SURGICAL SUTURES

Surgical sutures are applied during surgery and must be disinfected regularly to prevent sepsis. Proper hygiene and sterilization are essential for effective healing.

CONCUSSION

Concussion can result from a strong head impact with blunt objects, nearby explosions, or small-caliber hits stopped by a ballistic helmet. Initial symptoms include headache, dizziness, unstable coordination and blurred vision. It fades over time, but specific medications speed up recovery.

HEMOSTASIS (BLEEDING SPEED)

Hemostasis is the natural process by which the body reduces bleeding. Some medicines slow blood loss and buy time to stabilize or receive additional care.

HEMATOPOIESIS (BLOOD REGENERATION)

Hematopoiesis is the blood regeneration process. Specific medicines increase blood recovery speed and help you recover faster after scratches, cuts and bullet wounds.

Infections and Diseases

COLD / PNEUMONIA

Cold and flu can appear after prolonged exposure to low temperatures. If untreated, a mild cold can progress to pneumonia; at that stage health drops progressively. It is treated with suitable-level antibiotics (often with multiple doses). A mild cold may also resolve with warm rest.

FOOD POISONING

Food poisoning can come from spoiled or undercooked food, rotten fruit, poisonous mushrooms, dirty water, or accidental ingestion of substances like gasoline. Nausea and vomiting appear quickly; without treatment it can worsen with dehydration and progressive health loss.

CHEMICAL POISONING

Chemical poisoning occurs by inhaling toxic gas. Initial symptoms are coughing, then nausea and vomiting with progressive worsening. In advanced stages it causes severe health loss and can become fatal without rapid intervention.

ZOMBIE VIRUS

The zombie virus spreads through aerosols and bodily fluids, with low probability during close combat but much higher risk from wounds inflicted by zombies. Masks and ballistic protection reduce the risk. Incubation is long (over one real hour), leaving time to find an antidote; in the terminal stage, health collapses quickly.

SEPSIS

Sepsis occurs when an infection enters an open wound, for example after zombie scratches, knife wounds or bullet wounds. The risk increases significantly if the wound is handled with dirty hands. Without treatment, health progressively worsens.

RABIES

Rabies is transmitted by bites from infected animals, such as wolves. After infection it progresses in stages: in the first phase, symptoms are mild and easy to ignore; in the second, severe nausea and vomiting appear, blocking food and hydration; in the third phase, body temperature rises drastically with rapid health loss and very low survival chances. Without timely treatment it is lethal.

Sintomi

PAIN

Pain comes from different traumas and intensity depends on wound severity. It tends to decrease over time, but suitable painkillers accelerate functional recovery.

OVERDOSE

Overdose occurs when the body receives excessive amounts of medicines or toxic substances. The value decreases gradually as toxins are eliminated and can progress through three stages:

• Stage one: nausea, hallucinations and loss of clarity.
• Stage two: general deterioration and possible loss of consciousness.
• Stage three: critical deterioration with high risk to life.

Emotional States

SLEEP

Sleep is a core resource like food and water. If the sleep indicator turns yellow, yawning begins and vision worsens; with a red indicator, the character can faint from exhaustion. Warm places are ideal for sleeping: near a fire, in a tent, in a house or in a sleeping bag. You cannot sleep with freezing cold, extreme hunger or severe illnesses (stage 2 or above). During sleep, health and blood recover quickly, with a chance to recover from mild illnesses.

MENTAL HEALTH

Mental health can worsen under extreme stress: zombie attacks, prolonged exposure to psionic zones, or consuming human flesh. This can cause panic, hallucinations and disorientation, making survival much harder. Antidepressants help stabilize the psyche and reduce negative stress effects.

Zones

Psionic Zone

Psionic zones are dangerous areas with high levels of psychoactive effects that directly impact the character's mental health.

Effect behavior

1. The zone has an influence radius: the closer you get to the center, the stronger the effects become.
2. Psychic impact: inside the zone, mental health decreases and panic, hallucinations and abnormal reactions may appear.
3. Critical state: with mental state at zero, the character may perform unpredictable and lethal actions.

Psionic protection

To safely visit psionic zones, antidepressants are required. As an alternative, the PSI helmet is available, with standard 95% protection.
