Epidemiology of human inmunodeficiency virus infection: delay in diagnosis

Epidemiological surveillance of HIV infection has made notably progress over the last decade, improving knowledge of its characteristics and adapting treatment accordingly. On the other hand, the delayed diagnosis of HIV infection is still an important problem to reduce transmission and improve epidemic control both national and internationally. Although the increased availability of new testing technologies over the last ten years, progress, although statistically significant,in reducing late diagnosis in Spain has been, insufficient in terms of public health, meaning that additional efforts should be put in place to review strategies and increase accessibility to tests, population awareness and decrease the lost opportunities for early diagnosis.
