Stigmatisation is a process whereby an individual or group of individuals is induced to feel a sense of self loathing towards a trait they possess. Such a trait is usually capable of being linked to characteristics that are perceived as being negative. The distinguishing theme of stigmatisation is that individuals are induced to view themselves in a negative light. This is in contrast to the issue of discrimination where a change in the perceptions individuals have towards themselves may not exist or be even desired by those who discriminate. Stigmatisation can bring about harmful effects through a reduction in individual self-confidence and a resultant desire to hide the trait in question from others. This reduces the motivation of individuals in several important areas. This can manifest itself inter alia in health care avoidance behaviours and a reduced motivation to seek the necessary goods in life. The issues are capable of having grave negative consequences in the context of epidemics of infectious disease for both the individuals concerned and society as a whole.
