Resumen: HIV-2 and HTLV-1 infections are globally less frequent than those produced by HIV-1, the classical AIDS
agent. In Spain and up to the end of 2014, a total of 310 cases of HIV-2, 274 of HTLV-1, and 776 of HTLV-2
infections had been reported. No cases of HTLV-3 or HTLV-4 infections have been identified so far in Spain.
Most persons infected with HIV-2 or HTLV-1 acknowledge epidemiological risk factors for contagion, such
as originating from or living in endemic regions and/or having had sexual partners from those areas. However,
risk factors could not be recognized in up to 20-25% of carriers in Spain. Thus, it seems worth keeping a
high level of clinical suspicion in order to identify earlier these neglected human retroviral infections, since
diagnostic procedures and antiviral treatment are specific for each of these agents. In this article we
summarize the major contributions reported at the meeting of the Spanish Group for HIV-2/HTLV held in
Madrid in December 2014 Idioma: Inglés Año: 2015 Publicado en: AIDS REVIEWS 17, 4 (2015), 212-219 ISSN: 1139-6121 Factor impacto JCR: 2.068 (2015) Categ.
