Statistics on HIV/AIDS

The epidemiology of HIV/AIDS in Switzerland and globally


In 2019, there was a further decline in HIV diagnoses. For the third time since the beginning of the HIV epidemic in the early 1980s, fewer than 500 cases were reported to the FOPH. In the 1990s, the average number of cases per year was 1300. An increased testing regime, particularly of exposed groups, ever-earlier treatment and pre-exposure prophylaxis (PrEP) seem to have triggered a trend reversal.

  • Around 16,700 people in Switzerland live with HIV.
  • In 2018, 421 new HIV diagnoses were made in Switzerland. This number of diagnoses constitutes an historic low. The decreasing trend, which has been observed since 2008, continues.
  • The majority of reported HIV cases concerns men: their proportion, at 79%, remains virtually unchanged. In 2019, in common with previous years, sex with other men was cited as the most common route of infection (49.1%) for men diagnosed with HIV. This was followed by heterosexual contacts (24.8%). The use of contaminated injectables for intravenous drug use (IDU) was found in 3.3% of HIV diagnoses in men. In nearly a quarter of HIV diagnoses in men, the infection route was unable to be determined.
  • Between 2014 and 2019, the number of cases among women with heterosexual transmission declined almost steadily from 107 to 71. Among those women infected heterosexually, 42% were the nationality of a country classified as having a high HIV prevalence, according to WHO criteria. This proportion was lower among men with heterosexual transmission (12%). In Switzerland, it is principally African countries that play a role here, but in some cases also Caribbean countries.
  • The Swiss HIV cascade is far ahead in a global comparison: 93% of all persons living in Switzerland with HIV in 2019 have a corresponding diagnosis and thus knew of their infection, 97% of those diagnosed with HIV received treatment, and 96% of those with HIV treatment had a viral load below the detection limit, can therefore no longer pass on the virus.

2019, People living with HIV - All ages
  • There are 38 million people world-wide living with HIV (2019).

  • In 2019, 690'000 people died of AIDS. In 2010, this figure was 1.1 million.
  • There were approximately 1.7 million new HIV infections around the world in 2019. This represents a decrease of 23 % compared to 2010.
  • 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 38% overall compared with 2010.
  • By contrast, the number of new infections in Eastern Europe and central Asia has rocketed by 72% over the past six years.
  • In relation to the UNAIDS 90-90-90* targets, in 2019 81% of those living with HIV around the world were aware of their status, 82% of these people had access to treatment, and 88% displayed viral suppression.
