Methodological note

Definition of concepts

Acquired immune deficiency syndrome (AIDS)
Is a transmissible disease provoked by the human immunodeficiency virus (HIV). It is characterised by the appearance of one or more diseases (which is why it is called a syndrome) that develop as a consequence of alterations of the immunologic system.
Users of injected drugs (UDVP)
Collective with high probability of contracting AIDS due to the use of infectious material when administering drugs through injection through the skin.

Methodological aspects

In Catalonia, AIDS has been an individualised Notifiable Disease since 1987, while HIV infection was voluntarily notifiable from 2001 until 2010. On publication of Decree 67/2010, of May 25, HIV was made an individualised Notifiable Disease and became part of the epidemiological surveillance circuits of Catalonia.

In 1994, the Centre for Epidemiological Studies of HIV/AIDS of Catalonia (CEESCAT) was created as a technical body to support the Ministry of Health (DS) in the prevention and control of HIV/AIDS and also, from 2006, sexually transmitted diseases (STD), when it changed its name to the Centre for Epidemiological Studies of STD/HIV/AIDS of Catalonia (CEEISCAT).

The epidemiological surveillance of HIV/AIDS conducted by the CEEISCAT is based on three basic core issues: monitoring of the parameters of morbidity and mortality, monitoring of behaviour related with the acquisition of HIV and STD and monitoring of HIV diagnosis. These formal systems are complemented by different observational studies that help inform on the state of the epidemic and its determinants in Catalonia. The information is gathered and analysed using the Integrated Epidemiological STD/HIV/AIDS Surveillance System of Catalonia (SIVES), which is published in the form of an epidemiological report every two years. The centre's research includes the study of the natural history of HIV, the determinants of its transmission, the design and evaluation of preventative measures, the effectiveness and determinants of antiretroviral treatments and the behavioural determinants of risk and of access to healthcare services.
