RESUMO
The purpose of this study is an evaluation of HIV-2 pathogenicity through an epidemiological analysis, specially in Africa. It is acknowledged that the incubation, or more specially the lapse of time between the infection and the AIDS disease, is longer with HIV-2 than with HIV-1. More over, a certain number of surveys done in Africa show that the average age is higher with HIV-2 than with HIV-1; this is a regular sign of lower pathogenicity. It appears that the sexual transmission of the virus is the same for the HIV-2 and the HIV-1, but it is less effective from mother to baby. Furthermore this type of virus is less prevalent with AIDS patients or AIDS suspects than the HIV-1; and the follow-up of HIV-2 seropositives show that fewer people fall ill than with the HIV-1. A few signs of AIDS standard diagnosis are less frequent among HIV-2 infected patients than among HIV-1 infected patients. Opportunist or associated infections, like tuberculosis or malnutrition, are less often found in HIV-2 patients.

A study of direct genital swabs achieved in Abidjan, on 116 men and 131 women consulting for urogenital complaints, has revealed that the men show a prevalence of 28.4% Chlamydia trachomatis, and of 18.1% Neisseria gonorrhoeae. Concerning the women the prevalence of the same germs are 13.7% for Chlamydia trachomatis, and 4.6% for Neisseria gonorrhoeae. These results show the importance of Chlamydia trachomatis as a sexually transmitted disease in Abidjan (Côte-d'Ivoire). No differences were observed according to age in the two groups.

An assessment of the current and future mortality and morbidity from acquired immunodeficiency syndrome (AIDS) in Côte d'Ivoire was made using the results of the 1989 national survey of the prevalence of human immunodeficiency (HIV) infection in the country and the AIDS projection model developed by WHO. For 1989 it was estimated that about 25,000 AIDS cases in adults and children had occurred, although the total number of cases reported for 1989 (up to 1 July 1991) was about 13% (1:6.9) of this estimated total. It is projected that by 1994 in Côte d'Ivoire the cumulative number of cases of AIDS in adults will be 89,000, and that for infants and children the corresponding number will be 41,000. It was also projected that about 371,000 uninfected children will have been born to HIV-infected mothers in Côte d'Ivoire by 1994 and that many of these children will have been orphaned by the deaths of their mothers from AIDS.

Stool samples were collected from 300 persons of three classes of age (less than 6, 6-15, greater than 15) coming from urban and rural areas of Ivory Coast and tested for enteric viruses. This study has shown the high frequency of enteric viruses carriage, unrelated to sex or age. Carriage rates were significantly higher in rural areas than in urban areas. Both in urban and rural areas there was no difference of carriage among males and females. Polioviruses are predominant.

Classically, the North of Ivory Coast is not part of the "meningitis belt". However, recent health statistics put in light some recent outbreaks in this part of the country, the last one in the years 1983-1985. The authors have studied this last outbreak and it can be foreseen that these epidemics will appear again as in the more Northern countries. Therefore it is desirable to set up a monitoring system to better organize the fight against this disease.
