HIV situation in Norway in 2012

After a record high number of new HIV cases among men who have sex with men (MSM) in 2011, the number of HIV-positive people in this group declined in 2012. Among immigrants, the number of HIV-positive declined slightly compared to 2011. Among heterosexually-infected people living in Norway and drug users, the HIV figures are virtually unchanged compared to 2011.

The Norwegian Institute of Public Health still regards HIV infection to be one of the most serious infectious diseases with serious consequences both for the individual and for society. The institute closely monitors the HIV situation in Norway by anonymised notification from doctors to the Norwegian Surveillance System for Communicable Diseases (MSIS).

In 2012, there were 242 new diagnosed HIV cases in Norway, of which 166 (69 %) were men and 76 were women. This is a moderate decrease from 268 diagnosed cases in 2011 (figure 1), and is due to a decrease in proven cases among MSM and immigrants infected before arrival in Norway. Among heterosexually-infected people living in Norway when they were infected, the number of diagnosed HIV cases in 2012 remained unchanged from 2011. The incidence of HIV among drug users in Norway remains at a stable low level (table 1). In total there are now 5138 people diagnosed with HIV in Norway, of which 3460 are men and 1678 are women.

It is still too early to tell whether the decline in the number of new cases among MSM indicates fewer new infections in this group. The trend for many years has been years of high HIV figures which fall slightly in the following year. This may be due to natural fluctuations after a year of high testing activity and detection of new cases. The number of detected cases of gonorrhoea among MSM continued to increase in 2012 and the number of cases of syphilis remains at a high level, which does not indicate less unprotected sex among MSM.
