Does This Look Infected?

The second studio album by Canadian band Sum 41, released on November 26, 2002. It is their only album to feature a Parental Advisory label on the cover, despite the fact that other albums by the band also feature profanity. It was released in both explicit and edited versions.

The cover for Does This Look Infected? shows drummer Steve Jocz dressed as a zombie. It was chosen months before the title. The album was almost delayed by the label because the band members did not have a name for it on time until Whibley thought of the name Does This Look Infected?. The whole band laughed at the idea and chose it. The same idea was also used on the band's EP "Does This Look Infected Too?", except Jocz was replaced with Whibley, also dressed as a zombie.

"Does This Look Infected?" has received positive reviews from music critics. On Metacritic, the album has 75 out of 100. E! Online said that it "has a clutch of songs that mix chord-y abandon with raging rock riffs–and a heck of a lot of good times". Blender also gave it a positive review, saying, "So Sum 41 have grown up… a little…. It's all relative, and, crucially, it still rocks."

"Does This Look Infected?" debuted at #8 on the Canadian Albums Chart, selling 17,000 copies in Canada in its first week. The album gained commercial success, with singles "The Hell Song" and "Still Waiting" mainly gaining success on the modern rock charts. The album has since sold over 4.5 million copies worldwide, but the album did not have as much success as the band's previous album "All Killer No Filler".

The album was included at number 28 on Rock Sound's "The 51 Most Essential Pop Punk Albums of All Time" list. The band toured to celebrate its 10th anniversary in 2012, and its 15th anniversary in 2018, playing the album in its entirety. Whibley himself stated he was not satisfied with how the album was mixed, stating "I’ve always, always hated the way this album sounds. I hated it in the studio and it still bothers me. The demo I made myself at home sounded better than the final mix."
