Statistics on HIV/AIDS
The epidemiology of HIV infection: globally and in Switzerland
The number of newly diagnosed cases of HIV has remained steady for the second year in a row, following a downward trend in the period from 2008 to 2014.
- There are currently around 20,000 people in Switzerland living with HIV.
- 542 new cases of HIV were diagnosed in Switzerland in 2016. This represented an increase of 1% over the previous year. Before then, the number of HIV cases had fallen almost every year since 2008. 2016 was thus the second year in a row that the figures did not continue the previous downward trend.
- Women account for 22% of new diagnoses. Over the past six years, the number cases of women becoming infected from heterosexual contact has declined almost continually from 120 to 84.
- The number of cases of men being infected from heterosexual contact rose initially, but fell sharply in 2014. There were 30 fewer cases in this group in 2016 than there had been five years previously (2011: 135 cases).
- Looking at the past six years, no clear trend can be established in the number of HIV diagnoses among MSM, as figures have varied considerably from year to year. There were 221 new diagnoses in 2016, corresponding to around 49% of all cases.
- Among women infected from heterosexual contact, 27% were nationals of a country which is classified under WHO criteria as having a high prevalence of HIV. The main countries of relevance to Switzerland are those south of the Sahara in Africa, and certain Caribbean nations. Nationals from high-prevalence countries account for a much smaller number of new diagnoses in men, regardless of how they have become infected.

- There are 36.9 million people world-wide living with HIV (2017).
- Of this number, around 21,7 million have access to antiretroviral therapy. This is an increase of 2.3 million compared with 2016, and almost 14 million more than in 2010.
- In 2017, 940'000 people died of AIDS. In 2010, this figure was 1.5 million.
- There were approximately 1.8 million new HIV infections around the world in 2017 – the same figure as in 2016.
Viewed globally, the greatest decline in new infections has been in eastern and southern Africa, where half of all people with HIV live – numbers are down by 30% overall compared with 2010.
- By contrast, the number of new infections in Eastern Europe and central Asia has rocketed by 30% over the past six years.
- In relation to the UNAIDS 90-90-90* targets, in 2017 75% of those living with HIV around the world were aware of their status, 79% of these people had access to treatment, and 81% displayed viral suppression.
Data by UNAIDS, july 2017
UNAIDS embarked on its ‘90-90-90’ programme in 2014. Its objective is that, by 2020, 90 percent of those living with HIV will be aware of their status, 90% of those who have been diagnosed with HIV will be receiving anti-retroviral therapy (ART), and 90 percent of those in treatment will have a viral load that is #undetectable.
