The red ribbon is a worldwide sign for AIDS. This artwork is on the facade of the Aids-Hilfe Bremen-house.

It is part of an anti-AIDS campagne in Germany, to get as many people as possible tested for AIDS. The organization wants to reach young people to let themselves get tested, because infection number are rising amongst this group. Infected people who get treated are no longer contagious, so effectively the spreading of the disease will slow down or stop completely.
