Aircraft
On departure at 10;000 feet; Flight Attendant called the cockpit to report odor in the cabin and one Flight Attendant sick. We [requested ATC priority handling]; ran appropriate checklists and returned to ZZZ. Upon arrival to the gate medical personnel assisted.
During climbout the number one Flight Attendant advised that there were strong fumes in the cabin. The Captain and I were also advised that the number two Flight Attendant was not feeling well because of the fumes. The Captain advised me to [request special handling] for an immediate return to ZZZ. We ran appropriate checklists and landed. Crash Fire Rescue was called and responded to inspect the aircraft to ensure there was no outside indication of an issue. We [returned to] the terminal and had affected persons treated by medical personnel.Because the cause is unknown to me...I am not aware of any mitigation strategies other that allotting more resources in understanding; addressing; mitigating; and avoiding cabin fume events.
A321 flight crew reported being notified by the Flight Attendant in charge during departure climb of a strong cabin odor causing one Flight Attendant to experience health issues. Flight crew requested special handling to return to departure airport and executed a safe landing.
