# VIRUS
Description
VIRUS is an event plugin currently in development that introduces an infection system into Minecraft.
The virus spreads across the world, turning ordinary items and plants into sources of danger.
Players go through four stages of infection, each intensifying the symptoms and altering player behavior.
Stages of Infection
Stage 1 — Symptoms
- Effects: Blindness and Nausea
- The player experiences dizziness and disorientation.
- The virus is just beginning to take effect.
Stage 2 — Weakness
- Effect: Slowness
- The player’s movements become sluggish, and their reaction time worsens.
Stage 3 — Inventory Infection
- Some items in the player’s inventory turn into infected ones.
- The symptoms from the first stage disappear.
Stage 4 — Spread
- The player takes periodic damage.
- The virus begins spreading to nearby blocks from the player.
- All symptoms from the first stage vanish completely.
Infection Sources
Food
Players can get infected by eating contaminated or rotten food:
rotten flesh, raw chicken, raw beef, raw pork, raw mutton, raw rabbit, pufferfish, or poisonous potato.
There is a chance of infection when consuming these items.
Item Pickup
If a player picks up an infected item named “Virus”, they are immediately infected.
Containers
If a player attempts to take an infected item named “Virus” from a chest, barrel, or other container — they become infected.
Infected Blocks
A player becomes infected when stepping on an infected block recorded in blocks.db.
These blocks can further spread the virus to nearby plants and surfaces.
