National Programme for HIV and Other Sexually Transmitted Infections (NPHS)

The NPHS follows on from 25 years of successful prevention work. For the first time, other sexually transmitted infections (STIs) are being included in addition to HIV. The principal aim is to reduce the number of new infections with HIV and other STIs and to avoid consequences with an adverse effect on health. On September 6th 2017, the Federal Council prolonged the programme for 4 years from 2018 to 2021.


The NPHS is a national strategy for preventing, diagnosing and treating HIV and other STIs. You can download the programme here.

HIV/STI prevention among the general population (axis 1)

HIV and other sexually transmitted infections are most commonly spread through unprotected sexual intercourse. The national programme aims to prevent the further spread of infections in Switzerland.

Groups with a high risk of exposure (axis 2)

Axis 2 is directed towards people with risky behaviours in an environment where HIV and other STIs are widespread. Read more about the different projects here.

People living with HIV and their partner(s) (axis 3)

Advances in the field of HIV now mean that people with the infection who are being treated and have an undetectable viral load do not transmit the virus and have a life expectancy equal to that of those who are HIV negative.

Testing and counselling

HIV/STI testing without counselling is an opportunity missed for prevention. The FOPH encourages doctors and patients to discuss sexuality issues in the course of HIV/STI testing.

International integration of efforts against HIV&STI

Transmitted diseases do not stop at national borders. Efforts against HIV and other STIs must have an international dimension. Migration, international mobility and networking call for global measures.
