Critical reception Does This Look Infected? has received mostly 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."
Commercial performance Does This Look Infected? debuted at number eight 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".
Legacy The album was included at number 28 on
Rock Sounds "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." In February 2025, former drummer Steve Jocz ranked
Does This Look Infected? as his favorite Sum 41 album he has worked on. == Track listing ==
