HumanitZ Medical System Guide
In HumanitZ, the zombies are not the only thing trying to kill you. Diseases, infections, injuries, and environmental hazards are constant threats that can end a run just as effectively as a zombie bite. This guide covers the complete medical system: every disease and its cure, every injury type and its treatment, all medical supplies and where to find them, and the strategies for keeping your survivor healthy through weeks of post-apocalyptic survival.

The Health System — More Than Just HP
HumanitZ uses a multi-layered health system that goes far beyond a simple health bar. Your survivor has four core health metrics: HP (current health), Max HP (the ceiling that HP can reach), Stamina (physical exertion capacity), and Hydration (water level). Each of these can be reduced by different threats and restored by different treatments. Understanding the interplay between these metrics is the difference between a survivor who lasts a week and one who lasts a month.
Max HP is the most critical long-term metric. Certain injuries — gunshot wounds, severe infections, radiation sickness — temporarily reduce your Max HP. This means even if you heal to full, your health ceiling is lower than normal. A survivor with 60 Max HP instead of 100 is one zombie bite from death. Restoring Max HP requires specific treatments: Surgical Kits for gunshot wounds, antibiotics for infections, and RadAway for radiation. Stockpiling these items is essential for long-term survival.
Stamina is your short-term survival metric. Sprinting, melee attacks, and carrying heavy loads drain stamina. When stamina hits zero, you cannot sprint, your melee attacks deal reduced damage, and your aim sways more. Diseases like influenza and hypothermia reduce stamina regeneration, making every physical action harder. Painkillers temporarily boost stamina regen, but the real solution is curing the underlying disease. Hydration directly affects stamina regen — a dehydrated survivor regenerates stamina at 30 percent the normal rate.
Complete Disease Reference — Symptoms, Treatment & Prevention
HumanitZ features 7 distinct diseases, each with unique symptoms, transmission methods, and treatments. Some diseases are minor inconveniences; others are run-ending if untreated. This table covers every disease in the game so you can identify and treat them before they become lethal.
| Disease | Symptoms | Transmission | Treatment | Prevention |
|---|---|---|---|---|
| Influenza (Flu) | Sneezing, reduced stamina regen, blurred vision at night | Contact with infected zombies, contaminated water | Antibiotics (1 course), rest, clean water, vitamin C tablets | Boil all water before drinking. Avoid fighting zombies bare-handed. Wear gloves when looting. |
| Infection (Wound) | Red wound icon, gradual health drain (2 HP/min), fever visual effect | Untreated bite wounds, deep scratches from zombies | Antibiotics (2 courses), Bandage applied to wound, disinfectant spray | Bandage all wounds immediately. Carry disinfectant spray on every scavenging run. |
| Food Poisoning | Vomiting animation, rapid hydration loss, stamina penalty for 10 minutes | Eating raw or spoiled food, drinking untreated water | Charcoal tablets, clean water (extra intake), rest in safe area | Cook all meat at a campfire or stove. Check food freshness with the inspect action. Never eat canned food past its expiration date. |
| Dysentery | Severe dehydration, intermittent health drain, reduced carry capacity | Drinking from stagnant water sources, eating with dirty hands | Water purification tablets, antibiotics (1 course), oral rehydration salts | Only drink from Rain Catchers or boiled water. Build a Rain Catcher within the first 3 days. |
| Radiation Sickness | Vomiting, hair loss visual, 5 HP/min drain, permanent max health reduction | Entering irradiated zones (nuclear plant, military convoy crash sites) | RadAway (2 doses), Iodine tablets, extended rest outside radiation zone | Wear a Hazmat Suit in irradiated areas. Carry Iodine tablets at all times. Check radiation with a Geiger counter before entering unknown zones. |
| Hypothermia | Blue-tinted screen, slowed movement, shivering animation, stamina regen halted | Prolonged exposure to cold biomes, rain without proper clothing, night exposure | Heat pack (applied to body), warm clothing, stay near a campfire or heater for 5 minutes | Wear layered clothing in winter biomes. Carry 2 heat packs. Build a heated base with a fireplace or generator-powered heater. |
| Zombie Virus (Terminal) | Orange wound icon, progressive health drain, hallucination effects, death after 72 in-game hours | Bite from a Special Infected zombie (3 percent chance per bite) | No cure available. Experimental vaccine slows progression but does not stop it. | Never let a Special Infected bite you. Wear body armor to reduce bite penetration. If bitten, use the remaining time to transfer gear to teammates. |
Injury Types and Treatment Strategy
Combat in HumanitZ is dangerous. Every zombie encounter risks injury, and injuries compound. A survivor with a deep laceration and a concussion is at a severe disadvantage — bleeding drains HP while the concussion causes aim sway, making it harder to fight back. The key to survival is treating injuries in priority order: stop bleeding first, then address mobility issues (fractures), then treat infections, then restore HP.
Bleeding is the most urgent injury. A deep laceration drains 3 HP per minute — in a 5-minute fight, that is 15 HP lost to bleeding alone. Always carry bandages on your hotbar (slot 4 or 5) and apply them the moment you start bleeding. Disinfectant spray should be applied immediately after bandaging to prevent wound infection. If you do not have disinfectant, alcohol works as a substitute but is less effective.
Fractures are the most disruptive injury. A broken leg reduces movement speed by 60 percent, making it impossible to outrun zombies. If you fracture a leg during a scavenging run, your priority shifts from looting to survival. Apply a splint immediately (it takes 5 seconds) and call for extraction. In solo play, a fracture means you must walk — not run — back to your vehicle and drive home. Never attempt to fight zombies with a fracture; the movement penalty makes kiting impossible.
Complete Injury Reference — Causes, Severity & Treatment
Every injury type in HumanitZ, from minor scratches to compound fractures. Use this table to identify injuries and apply the correct treatment quickly.
| Injury | Cause | Severity | Bleeding | Treatment | Long-Term Effect |
|---|---|---|---|---|---|
| Minor Scratch | Zombie claw attack (glancing hit), barbed wire, broken glass | Low | No | Bandage (prevents infection). No HP restoration needed. | None if disinfected. If untreated, 15 percent chance of wound infection within 2 hours. |
| Deep Laceration | Zombie bite (blocked by armor), melee weapon hit from hostile survivors, sharp debris | Medium | Yes (3 HP/min until bandaged) | Bandage + Disinfectant Spray. Apply First Aid Kit for HP restoration. | If untreated, 40 percent chance of wound infection. Bleeding drains health rapidly during combat. |
| Zombie Bite (Penetrating) | Unblocked zombie bite, Special Infected bite | High | Yes (5 HP/min, severe) | Bandage immediately to stop bleeding. Antibiotics to prevent infection. No cure for zombie virus if contracted. | High infection risk. 3 percent chance of zombie virus from Special Infected. Monitor for orange wound icon for 24 in-game hours. |
| Gunshot Wound | Friendly fire, hostile survivor attacks, trap misfire | High | Yes (8 HP/min, severe) | First Aid Kit + Antibiotics. Surgical Kit required for full recovery (restores max HP cap). | Reduces max HP by 10 until treated with Surgical Kit. Permanent stamina penalty if untreated for 24 hours. |
| Fracture (Broken Bone) | Falling from height (2+ stories), vehicle crash at high speed, Tank slam attack | Very High | No (internal damage) | Splint (2 Wood + 1 Cloth) + Morphine for pain. Requires 6 in-game hours to heal with splint applied. | Movement speed reduced by 60 percent until splint applied. Cannot sprint or jump. If untreated, permanent mobility reduction. |
| Concussion | Explosion proximity (Molotov, grenade), vehicle collision, Tank knockback hit | Medium-High | No | Painkillers + rest (10 minutes in safe area). No specific medical item required. | Blurred vision for 5 minutes. Aim sway increased by 50 percent. Reduced reaction time. Faint chance if untreated for 30 minutes. |
Medical Supplies — Locations, Crafting & Usage
Medical supplies are the most important non-weapon items in HumanitZ. A well-stocked medical kit is the difference between surviving a bad encounter and losing your run. Every survivor should carry a minimum medical loadout on every scavenging run: 5 bandages, 2 First Aid Kits, 4 antibiotic doses, 1 disinfectant spray, 2 painkiller doses, and 2 charcoal tablets. This loadout covers 95 percent of medical emergencies you will encounter.
The most efficient way to stockpile medical supplies is to map out pharmacy and hospital routes early. Hospitals have the highest spawn rates for First Aid Kits, Antibiotics, and Surgical Kits. Pharmacies have reliable spawns for Bandages, Painkillers, Disinfectant Spray, and Charcoal Tablets. Military locations (checkpoints, bunkers) are the only reliable source of RadAway and Iodine Tablets. Mark these locations on your map and visit them every 3-4 days as loot respawns.
Once you have a Chemistry Table (Level 3 Medical required), you can craft your own antibiotics, disinfectant spray, and charcoal tablets. This eliminates the need to scavenge for the most critical medical items. The Chemistry Table blueprint is found in hospital basements and military research facilities. Prioritize finding it within the first 2 weeks. Once operational, it transforms your medical supply chain from scavenging-based to crafting-based, which is far more sustainable for long-term survival.

Long-Term Health Management Strategy
Surviving the first week is about reacting to immediate threats. Surviving the first month is about building systems that prevent those threats from occurring. The most important long-term health strategy is establishing a clean water supply. A Rain Catcher provides unlimited purified water, eliminating dysentery and food poisoning risk from contaminated water. Build one within the first 3 days — it requires 4 Wood, 2 Plastic Sheet, and 1 Rope, all easily scavenged materials.
The second pillar of long-term health is a mold farm for antibiotic crafting. Place bread or fruit in a container near a water source and wait 3 in-game days. The resulting Mold Culture is the key ingredient for crafted antibiotics. With a Chemistry Table and a steady supply of Mold Culture, you never need to scavenge for antibiotics again. This frees up scavenging time for other priorities and ensures you always have antibiotics when you need them.
Finally, invest in preventive equipment. A Hazmat Suit (found in military bunkers) eliminates radiation sickness risk entirely. Layered winter clothing eliminates hypothermia in cold biomes. Body armor reduces the severity of zombie bites, lowering the chance of wound infection. These items are expensive in terms of carry weight and scavenging time, but they eliminate entire categories of medical threats. A survivor in a Hazmat Suit with layered armor and a clean water supply has effectively eliminated 5 of the 7 diseases from their threat list.
Frequently Asked Questions
How do I cure wound infection in HumanitZ?
Wound infection requires 2 courses of antibiotics and a fresh bandage applied with disinfectant spray. The infection icon turns from red to orange as it worsens. If you catch it early (red icon), one course of antibiotics plus disinfectant spray is enough. If the icon has turned orange, you need the full 2-course treatment plus a First Aid Kit. Never ignore wound infections — an untreated infection drains 2 HP per minute and eventually becomes terminal. Always carry at least 4 antibiotic doses on every scavenging run.
What is the fastest way to heal in combat?
The fastest combat heal is the First Aid Kit, which restores 40 HP and stops bleeding in one action. Bandages restore only 10 HP but are faster to apply (2 seconds vs 5 seconds for First Aid Kit). The optimal strategy is to bandage first to stop bleeding, then retreat to cover and use a First Aid Kit for the HP boost. Painkillers can be taken simultaneously for an additional 5 HP and a stamina boost. Never use a First Aid Kit while actively bleeding from a deep laceration — the bleeding cancels the HP restoration over time.
Can I craft antibiotics or do I have to find them?
Antibiotics can be crafted at a Chemistry Table with Level 3 Medical skill. The recipe requires 2 Mold Culture, 1 Purified Water, and 1 Alcohol. Mold Culture is obtained by leaving bread or fruit in a damp container for 3 in-game days. This makes antibiotics renewable once you have a Chemistry Table and a mold farm setup. However, early-game players must scavenge antibiotics from pharmacies and hospitals. Prioritize finding a Chemistry Table blueprint within the first 2 weeks — it transforms medical supplies from a finite resource to a renewable one.
