[Course of HIV2 seroprevalence at the National Hospital of Niamey (Niger)]. 1996

H Ousseini

Faculté des Sciences de la santé, Niamey, Niger.

About the 25,368 serological tests done among the different groups of the population at the biological laboratory of the National Hospital of Niamey from March 1987 to May 1990, the author studied the seroprevalence evolution of the infection HIV2. A regular fall for the HIV2 appeared in this period. The author tries to explain this fall of the HIV2 in a country newly infected by the HIV by the lower infectivity of the HIV2 and/or a failure to adjust of this virus in Niger.

D000163	Acquired Immunodeficiency Syndrome	An acquired defect of cellular immunity associated with infection by the human immunodeficiency virus (HIV), a CD4-positive T-lymphocyte count under 200 cells/microliter or less than 14% of total lymphocytes, and increased susceptibility to opportunistic infections and malignant neoplasms.

D015498	HIV-2	An HIV species related to HIV-1 but carrying different antigenic components and with differing nucleic acid composition. It shares serologic reactivity and sequence homology with the simian Lentivirus SIMIAN IMMUNODEFICIENCY VIRUS and infects only T4-lymphocytes expressing the CD4 phenotypic marker.
