UltimateVirus BIG UPDATE to BETA-2.0.2 - PlaceholderAPI support!
NOTE: I'm really sorry, but considering that i changed the config.yml, the database and the lang.yml, you must delete the Ultimatevirus folder in order to make this version work.
Added:
Placeholder API support (placeholder: %ultimatevirus_isInfected%);
Configurable messages for the placeholder;
Configurable maximum health when a player is infected;
A list of worlds in which the virus won't spread;
Check if a player is infected also if he is offline.
