Identifying Infected: A Guide to Quarantine Zone Symptoms

Being aware of the symptoms in the Quarantine Zone is crucial for keeping your camp secure. You’ll want to ensure that only those survivors who are confirmed to be free of the lethal virus are allowed in. However, this task becomes increasingly challenging as new symptoms emerge over time, necessitating the use of advanced tools to keep pace with the virus’s mutations. To help you navigate this, here’s a comprehensive rundown of the symptoms in the Quarantine Zone and guidance on how to identify new ones using the Laboratory. Have you figured out the identity of the skeleton guy in the Quarantine Zone or located all the “Ask Your Mom” poems scattered around the camp?

As you progress, the list of symptoms available for diagnosing incoming survivors will expand. Some symptoms will be added as you unlock new tools, while others will require you to send a survivor showing that symptom to the Laboratory for official identification. Below is a complete list of Quarantine Zone symptoms for your reference:

When a survivor approaches the checkpoint and displays an unidentified symptom from the list, you can send them to the Laboratory for further examination. Make your way to the lab and interact with the computer on the desk to initiate the procedure. This involves maneuvering a laser to remove unnecessary organs and reach the one you need to analyze.

Be careful to only destroy organs highlighted in orange, as targeting red organs could lead to a failed procedure. If you successfully identify the green organ, hold E to extract it before the timer expires to earn bonus science points. Afterward, retrieve the organ and place it in the extractor, then take the blood sample and deposit it into the analyzer. If the survivor had a new symptom, it will be added to your list for future reference.
