Infection
Some zombies infect you when they hit you. The infection grows by itself, from 1 to 100, and gets worse at each stage. At 100 you are Turned, and if you die while you are Turning or Turned, you come back as a zombie.
The 4 stages

Now and then you cough (a small green cloud). Nothing else yet: the best time to cure it.

You are weak all the time and get poisoned for 2 s every 12 s.

Weakness II and slowness. Every 8 s your sight goes dark or blind for a moment and you get poisoned.

Wither and slowness II. Cure it now: if you die, you come back as a zombie.
Every bite that infects adds to the level (15 for most zombies). Then the level goes up by 1 every 3 seconds, 20 per minute: from a first bite to Turning takes under 3 minutes. A bandage stops it for 45 seconds. Die while Turning or Turned and you rise as a zombie: One-Armed Zombie, Farmer, Crawler.
How to treat it

Cures the infection completely and gives 6 s of regeneration.

Full health, removes poison, wither, nausea, slowness and weakness, and the infection goes down by 30.

+6 health and the infection is paused for 45 s.

Infection -5, and bites cannot infect you for 60 s.
Also good to know
When an Explosive Virus Barrel bursts, everyone within 3 blocks gets +15 (even in a Hazmat suit).
When a Bloater bursts next to you, 17.5% chance to be infected (+10).
The Biker set halves the chance that a bite infects you; the Hazmat set divides it by 4.
The monitor
A small holographic monitor shows up next to your left hand for 5 seconds every minute while you are infected, and right away after a bite or a new stage. The bar has 20 segments (one per 5 levels); the newest one blinks. After a treatment it shows what the treatment did for 3 seconds. It never takes the place of a totem: with a totem in your off hand, the infection shows in the action bar instead.

After a bandage the monitor says PAUSED. After a treatment:
