There's an ailment called 'Disease', very nasty. Once you get that in your system, your wounds... they won't heal.

Virus (ウイルス, Uirusu?), sometimes called Disease or Pointless, is a negative status effect appearing in various games in the Final Fantasy series. It is normally not visible during a fight except by checking a character's status in a menu during the fight. Virus places some kind of restriction on the afflicted that is not easily removed, but the exact effect varies between games.
Appearances[]
Final Fantasy IX[]
Virus prohibits a character from earning EXP and AP at the end of a battle, stunting character growth. In addition, Virus nullifies the target's Evasion stat. Virus can be removed by use of a Vaccine. When Eiko has Guardian Mog active, Virus will be healed before the Battle Results screen appears, meaning she still gains EXP and AP even if she contracted Virus mid-battle.
Final Fantasy X-2[]
Pointless prohibits a character from earning Experience and Ability Points. It can be cured with Holy Water. The character inflicted will start flashing slowly.
Final Fantasy XI[]
Virus (divided into Plague or Disease) inhibits the regeneration of HP and MP through Healing. Players can still gain some HP and MP through Cures, Regen, and Refresh, as well as items that grant similar bonuses, however. The variation effect Plague instead slowly saps MP and TP until it wears off. Both status effects can be removed by casting Viruna on the inflicted.
Final Fantasy XII[]
Disease makes a target's Current HP into their new Maximum HP. Even though the target receives damage, the health bar does not drop while their actual HP does, but even Libra cannot detect the actual current HP. Enemies may combine Disease with Poison and/or Sap, which will eventually reduce a character's HP to 1/1 (in such a state, the character is not regarded as HP Critical).
Disease is cured with a Serum (Vaccine), the White Magick Cleanse, the spell Bubble or a Remedy, provided the character has the required license, Remedy Lore 3. Characters who are currently in Bubble status will be immune to Disease, and vice versa. A KO'd character with Disease status will have only 1/1 HP when revived. With the accessory Nihopalaoa equipped, a character can inflict Disease on enemies by using Serum on them; Remedy with Remedy Lore 3 will inflict Disease and other statuses as well.
Final Fantasy XIV[]
Virus was an Arcanist ability that reduced the target's Strength and Dexterity by 15%. It was removed with the release of Final Fantasy XIV: Stormblood (4.0), and the Caster Role Ability Addle was considered a replacement for it.
Final Fantasy Brave Exvius[]
Disease lowers the afflicted party members' ATK, DEF, MAG, & SPR by 10% - which dampens the units' damage outputs, overall damage resistance, and magic healing potency - all in addition to any stat debuffs inflicted through offensive Abilities.
Disease is cured with a Vaccine, the White Magic Cleanse, or certain characters' Special Abilities and Limit Bursts. Disease is normally a persistent ailment over multiple battles or ongoing Explorations, but Terra, Trance Terra, Moogle, and Eiko cure their ailments after each battle with Terra's, Trance Terra's, and Moogle's passive ability Guardian Mog and Eiko's Mog's Friendship.
