Naruto: Outbreak

is episode 183 of the Naruto: Shippūden anime.

Synopsis
Sakura, Shizune and Tonton are all sitting in a tent camped by Tsunade, who has remained in a comatose state since Pain's invasion. Chōji and Naruto arrive with lunch for them. As Naruto leaves to aid in the rebuilding of Ramen Ichiraku, Chōji and Shizune comment on his energetic personality and Chōji's quote leads Sakura to a flashback. She recalls the day when Naruto returned from a mission in an unknown village and appeared to be sick. Naruto sneezed on Sakura, who was about to depart on a mission. Later, after overeating at Ramen Ichiraku, Naruto was resting in his apartment when a group of Konoha medical-nin attempted to capture him. Throughout the episode Naruto eluded the medical team and other characters who had been ordered by Tsunade to capture him. After interrogating a medical-nin, Naruto learns that his capture was under Tsunade's orders as she believes that he is the carrier of a rare and dangerous chakra virus that affects a person's ability to mould chakra. Since the village was still recovering from the invasion of Konoha, Tsunade did not want anything to cripple the village. After Naruto was eventually captured and sent to Konoha Hospital it was discovered that he was never infected. Naruto, infuriated at Tsunade's actions, demanded an apology. Tsunade merely said that it was an emergency drill and thanked Naruto for co-operating. Naruto remained angry at her and exploded in a fury of rage as Sakura ends the flashback. She then notes that Chōji's quote, "Fools never catch a cold", may be true in Naruto's case, but that he certainly knows how to stir things up.
