Does the "Fresh Air in the Tunnels" buff need to be used immediately? - Wanted Lettering Text on Black Background

I did a quest and got the event "Fresh Air in the Tunnels", which provides extra Damage and Resolve in the Warrens on the next quest.

Do I need to do a quest in The Warrens this week to use the buff? If I go to the courtyard to get The Blood instead, will the buff have gone by next week?
