STI screening

Regular STI tests are necessary, since the majority of STIs do not cause any symptoms. Early detection allows the infection to be treated quickly, and most STIs can be successfully treated if this is the case.

In Switzerland, screening usually tests for the “BIG 5” infections: syphilis, gonorrhoea, chlamydia, hepatitis C and HIV.

Where can I be tested?

a)   At Aspasie:

Aspasie organises regular STI screening (around twice a month) at its premises.

The tests are free of charge and are only for sexworkers.

It can detect HIV/AIDS, hepatitis B, syphilis, gonorrhoea and chlamydia infections.

STI screening can also be carried out at private laboratories or in hospitals.
