How to detect an infected in Quarantine Zone: The Last Check? All symptoms explained

Quarantine Zone: The Last Check takes a different approach to handling the zombie apocalypse. Instead of directly fighting the undead, your primary duty is to look after the outpost.

There will be new survivors daily pouring in for your help, with the ultimate aim of reaching the safe zone. However, the job is easier said than done, since some of them might be infected. Let’s find out how you can tell who is safe to send to the survivors’ quarters, and who isn’t.

What are symptoms in Quarantine Zone: The Last Check

Symptoms are clear signs of whether an incoming survivor is clean or not. By clean, I mean whether they’re potential infected or not. Some symptoms can be clear to spot, while others might be hidden. As you play more, you’ll get new gear.

Let’s quickly look at what you want to spot carefully when accepting a survivor. While I am yet to get all the devices in the full version of the game (reached till Scanner), here are all the key things to note.

• Basics: Yellow eyes indicate chances of potential infection, while Red means danger. Similarly, freckles are okay, but scratches and bite marks aren’t. Bite marks are more dangerous than scratches. Once you get the Scanner, you can discover hidden marks.
• Thermopulse: If the Pulse is elevated, there’s a high chance that the survivor is infected. The same can be applied if the temperatures are high.
• Hammer: If the survivor hits you by reflex, chances are that they’re infected.

As you unlock more devices, you’ll obtain more symptoms to look at. Here’s a complete list of all symptoms in the game.

Guy 1 clearly has symptoms of an infection in his eyes, but there are no bite marks on his body. His eyes aren’t red, so I decided to send him to the quarantine.

Guy 2 has red eyes and an obvious bite mark on his face. He’s almost sure to turn into an undead, and that’s why I decided to send him to the chopping block. That’s precisely how you’ll have to keep your base in check and ensure that an infection doesn’t break through.
