Infections: blood-borne

Summary statistics for blood-borne infections in Scotland are given below. Detailed surveillance data and trend information are available from the Blood-borne viruses section of the Health Protection Scotland (HPS) website.


  • In 2015, 361 diagnoses of HIV were reported to HPS. This figure compares with an annual average total of 359 in the previous five years (2010-2014).
  • Sexual transmission is the major route of transmission of HIV in Scotland with sexual intercourse between men and women accounting for 25% (91/370), and sexual intercourse between men accounting for 38% (137/361) of all new reports in 2015. However, the transmission category is, as yet, undetermined for over one fifth of reports (80/361).
  • There were 52 reports of HIV among people who inject drugs (PWID) in 2015, compared to an annual average of 18 between 2011 and 2014. This increase in reports has been largely driven by an outbreak of HIV among PWID in the NHS Greater Glasgow and Clyde area during 2015.

  • Of the 361 cases reported during 2015, 119 (33%) are presumed to have acquired their infection outwith Scotland (this figure excludes several which are undergoing follow-up for epidemiological information), most likely in areas of the world with a high prevalence of HIV infection. While this proportion may change, this is the lowest proportion since the peak in 2009 (65%).

Detailed HIV and AIDS surveillance data and trend information are available from the Blood-borne viruses section of the Health Protection Scotland (HPS) website.

Hepatitis B

  • There have been some new developments in the surveillance of hepatitis B in Scotland which provide a greater understanding of the incidence and prevalence of infection. In 2015, there were 418 new reports of hepatitis B infection, the majority of these being chronic infection (395). This is lower than the total reported in 2014 (485).

Hepatitis C

  • Information on hepatitis C is presented in the hepatitis C section of the ScotPHO website.

Detailed Hepatitis C surveillance data and trend information are available from from the Blood-borne viruses section of the Health Protection Scotland (HPS) website.

In addition, the HPS Weekly Report publishes monthly and quarterly surveillance reports for each of the areas that HPS cover. Current and archived issues of the HPS weekly report can be accessed from the Publications section of the Health Protection Scotland website.
