Conjunctivitis (Quarantine): Red edges around the eyes; no internal changes in the Matioscope.

- Quarantine: Survivor fights back.
- Infected: Opposite limb moves in response.
Matioscope (Advanced Scan)
- Safe: Body has adenoviral or ocular parasites.

- Infected: Signs include necrosis or abnormal eye/infection markers.

- Safe: Organ shows signs like fatty Hepatosis or internal bleeding.
- Quarantine: Purple or pink discolorations.
- Infected: Necrotic organs with black patches.

How to Identify New Symptoms Using the Laboratory

If a survivor shows signs you haven’t identified yet, send them to the Laboratory for further study. Approach the computer inside and use the laser to burn away excess organs, revealing the one you need to analyze. Only destroy organs marked in orange, not red—destroying a red-marked organ risks failing the procedure. If you target the green-organ, hold E to extract it before time runs out to gain extra points. Afterward, collect a blood sample and analyze it; if a new symptom was present, it will add to your list for future identification.
