Safe vs Infected Symptoms
Quick reference guide to distinguish harmless symptoms from infection signs
Color Rating System
Quarantine Zone uses a three-color system to classify symptoms. Understanding this system is crucial for making correct decisions.
Green - Safe
Indicates sickness but NOT infection. Survivors with ONLY green symptoms can safely enter the Survivors Block.
Orange - Quarantine
May be sickness OR early infection. Requires observation in Quarantine for 1-2 days to monitor progression.
Red - Infected
Definite infection sign. Survivors with ANY red symptom must be sent to Liquidation immediately - there is no cure.
Safe Symptoms (Green)
These symptoms look alarming but do NOT indicate zombie infection. A survivor with only these symptoms is safe to admit.
Visual Inspection
Yellow Eyes
Whites of the eyes turn bright yellow. May indicate jaundice but not infection.
Freckles
Small brown or orange dots across cheeks and nose. Purely cosmetic, no infection relevance.
Herpes
Small misshapen brown/red splotches without pustules. A common condition, not infection.
Bruises
Blue, green, and yellow mixed splotches. Normal injury bruising, not necrosis.
Red Skin
Facial reddening or blush on cheeks or entire face. Only appears on the face.
Nosebleed
Two lines of red blood from each nostril. Different from green nose pus.
Stethoscope
Sickly Breath
Breathing with a slight wheeze. Indicates respiratory illness, not zombie infection.
Reflex Hammer
Absent Reflex
Arm barely moves when hit - only a tiny jerk, no swing. Different from crossed reflex.
Matioscope
Ocular Spicular Bacterium
Pink/orange tube with branches that occasionally twirls. A harmless eye organism.
Thread Cluster
Bundle of white threads that remains stationary. Common eye floater.
Ocular Helminth
Small translucent worm that wiggles in a straight line. Parasitic but not infectious.
Adenoviral Body
Greenish-orange ball with long nubs that occasionally pulses. Viral but not zombie-related.
X-Ray
Internal Bleeding
Organ still normal reddish color but covered in bleeding sores. Different from necrosis.
Fatty Hepatosis
Organ covered in yellow splotches. A liver condition, distinct from blue moldy organ.
UV Tower
UV Vapor
Green mist surrounding parts of the survivor under UV light. Floating in air, not on skin.
Infected Symptoms (Red)
Any ONE of these symptoms confirms zombie infection. Do not quarantine - send directly to Liquidation.
Visual Inspection
Red Eyes
Whites of the eyes turn bright red (not just irritated corners like conjunctivitis).
Green Skin
Entire body's skin appears green or very yellow. Systemic infection sign.
Necrosis
Several dark BLACK splotches on skin. Different from bruises which are multi-colored.
Bite Mark
Visible bloody human teeth marks. Every bite in this game is a zombie bite.
Eye Pus
Small drop of GREEN pus at the corner of the eye. Can be very small.
Nose Pus
Drop of GREEN pus from one nostril. Different from red nosebleed.
Thermopulsometer
High Temperature
Temperature above 105°F (41°C). Beyond survivable human fever range.
Extreme Pulse
Pulse over 180 BPM. Dangerously abnormal heart rate.
Stethoscope
Infected Breath
Sounds like a zombie GROWLING instead of any kind of breathing. Unmistakable.
Reflex Hammer
Crossed Reflex
Hit one arm, the OPPOSITE arm swings instead. The 'smoking gun' of infection.
Matioscope
Necrotic Plume
Dark black, blurry smudge in the eye. Usually vaguely diamond shaped.
Corneal Infiltrate
Dull green ball with tiny brown nubs. Distinctly different from safe organisms.
X-Ray
Moldy Organ
Organ colored teal BLUE. Very different from yellow fatty hepatosis.
Organ Necrosis
Organ almost fully covered in dark BLACK splotches. Death of tissue.
UV Tower
UV Contraband
Green glowing SPOT on backpack items under UV. Check items before confiscating.
UV Symptom
Hidden symptoms (bites, necrosis, pus) that GLOW GREEN directly on skin under UV.
Objects/Baggage
Contaminated Baggage
Any bloody human parts (limbs, fingers, heads, bones, organs) in backpack. Biohazard.
Commonly Confused Symptoms
These symptom pairs are commonly confused. Pay close attention to the distinguishing features.
Yellow Eyes
Bright YELLOW whites
Red Eyes
Bright RED whites
Use Matioscope - entire inside will match the color
Bruises
Blue/green/yellow MIX
Necrosis
Pure BLACK splotches
Bruises are colorful; necrosis is always black
Nosebleed
RED blood lines
Nose Pus
GREEN pus drop
Color is key - red blood vs green pus
Absent Reflex
Arm doesn't move at all
Crossed Reflex
OPPOSITE arm moves
Absent = no reaction; Crossed = wrong arm reacts
Fatty Hepatosis
YELLOW splotches on organ
Moldy Organ
BLUE colored organ
Yellow = fatty; Blue = moldy (infected)
Internal Bleeding
Red organ with bleeding sores
Organ Necrosis
BLACK splotches covering organ
Bleeding = red with sores; Necrosis = black patches
UV Vapor
Green mist in AIR around body
UV Symptom
Green glow ON SKIN
Vapor floats; UV Symptom is on the body
Quick Decision Rules
Safe to admit - they're sick but not infected
Observe for 1-2 days. May recover or worsen
Immediate elimination - no cure exists
High probability of infection - don't risk it
Contaminated baggage = treat as infected
Warning
When in doubt, quarantine. It's better to observe than to let an infected survivor into the living block.
