Use of new technologies to notify possible contagion of sexually-transmitted infections among men.

Background: Among men who have sex with men (MSM), the association between searching for sexual partners' on the Internet and increased risk of sexually transmitted infections (STIs)/HIV infection, together with current low levels of partner notification (PN), justifies a study to explore the intention to use new communication technologies for PN in Spain.

Methods: Two cross-sectional surveys were performed: the first was administered online to visitors to web pages where the survey was advertised; the second was administered on paper to patients attending an STI Unit and centres similar to Community-Based Voluntary Counselling and Testing centres.

Results: The study population comprised 1578 Spanish residents (median age, 34 years [range: 18 to 74]); 84% lived in urban areas, and 69% reported searching for sexual partners on the Internet.
