Hepatitis B and Injection Drug Use in Sweden, 2012

"Between 100 and 200 cases of acute hepatitis B are reported in Sweden annually. However, fewer cases of acute hepatitis B (82) were reported in 2012 due to fewer cases being reported among injecting drug users. Of all acute hepatitis B cases, 18 were among IDUs (compared with 51 cases in 2010), 17 of whom were infected in Sweden. The median age of IDUs diagnosed with acute hepatitis B in 2012 was 36 (range 19-52) (Smittskyddsinstitutet, 2013).
"The number of acute hepatitis B cases among IDUs varies depending on local outbreaks and immunity in the group following vaccination or previous infection. Other relevant factors are frequency in testing, injection behaviour and access to sterile equipment."
