Welcome to KOSI.MA!

KOSI.MA, the competence center for sexually transmitted infections in Mannheim, is an offer for all citizens who have questions about the subject of HIV / AIDS and other sexually transmitted infections (STIs).

Questions we can offer support with could be:

  • How can I protect myself from sexually transmitted infections such as HIV, chlamydia, syphilis or hepatitis?
  • Did I have a risk situation during sex?
  • I am HIV positive - what happens next?
  • Who should I tell about my infection?
  • Will my relationships be affected by my infection?

You can reach us via phone (except on public holidays) on:

Tuesdays 3:00 p.m. - 6:00 p.m.

Thursdays 9:00 a.m. - 12:00 a.m.

No matter what sexual orientation or identity - you are welcome!

Summer break

We are closed from the 22nd of August until the 4th of September. You can still reach us during the regular calling times (see above) and the Checkpoint on the 24th of August (see below) will take place.

MPX / Monkeypox virus

The first MPX cases in Mannheim have been confirmed. You can find information about MPX, symptoms, prevention and therapy on this page by IWWIT or contact us for free counseling.


If you suspect having been exposed to a risk of infection, you can be tested at the checkpoint. We offer a detailed and non-judgemental consultation before getting tested which promotes a more conscious health behavior. The consultation and testing is confidential. Due to Covid-19 security measures you have to make an appointment for the checkpoint though.

Next regular date:
August 24th, 06:00-07:30 pm
Appointments can be made via phone (see above).

We are currently adapting our Checkpoint offer to Covid-19 security measures. You can receive further information via phone.
