Festering Ridden is a Corruption Card with the Ridden 
affinity that can be used by the Director to jeopardize the mission of the Cleaners.
When the Director plays this card it will spawn Festering Commons that inflict a stacking debuff on Cleaners that is showcased by an 
-icon at the bottom of the screen along with the number of stacks. The effects can be removed by using Medkits, First Aid Cabinets, and Seo-yeon's healing ability. Although the card text does not mention it, this negative status effect can also be removed by the card effect of Cleansing Fire.
