Especially in community settings, influenza outbreaks can be difficult to control and can result in high attack rates. In April 2022, a large A(H3N2) influenza outbreak spread in the largest Italian drug-rehabilitation community. One hundred eighty-four individuals presented influenza-like symptoms (attack rate of 26.2%); 56% previously received the influenza vaccine. Sequence analyses highlighted a genetic drift from the vaccine strain, which may have caused the observed lack of protection.<\/jats:p>","DOI":"10.1017\/s0950268823000055","type":"journal-article","created":{"date-parts":[[2023,1,19]],"date-time":"2023-01-19T09:33:27Z","timestamp":1674120807000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":0,"title":["A large A(H3N2) influenza outbreak with a high attack rate in a drug user community in Italy, April 2022"],"prefix":"10.1017","volume":"151","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6478-2791","authenticated-orcid":false,"given":"Maria","family":"Gori","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1573-5531","authenticated-orcid":false,"given":"Clara","family":"Fappani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1365-9408","authenticated-orcid":false,"given":"Silvia","family":"Bianchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9959-128X","authenticated-orcid":false,"given":"Marta","family":"Canuti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4079-1957","authenticated-orcid":false,"given":"Daniela","family":"Colzani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paolo","family":"Ottogalli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sarah","family":"Duehren","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4119-701X","authenticated-orcid":false,"given":"Elisabetta","family":"Tanzi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0499-8977","authenticated-orcid":false,"given":"Antonella","family":"Amendola","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio","family":"Boschini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2023,1,19]]},"reference":[{"key":"S0950268823000055_ref1","doi-asserted-by":"publisher","DOI":"10.1017\/S0950268804003243"},{"key":"S0950268823000055_ref8","doi-asserted-by":"publisher","DOI":"10.15585\/mmwr.mm7122a4"},{"key":"S0950268823000055_ref7","unstructured":"7.
