HIV: Three quarters of women infected through heterosexual
Three-quarters of HIV-positive women were infected through heterosexual contact, against just over a third of men, according to the assessment of compulsory notification of HIV and virological surveillance.
Mode of transmission of HIV
1843 notifications were recorded by the Institute of Health Surveillance (VS). Only 1301 were analyzed, the detailed results were published in the Weekly Epidemiological Bulletin says InVS in a statement.
Data already allow that the proportion of women has now reached 43% of new diagnoses of HIV infection. Women are screened at 33 and a half years on average, at an earlier age than men (39 and a half years).
More than half of new infections involve people infected through heterosexual intercourse, and 21% homosexual. The IDU is responsible for only 3% of new infectious cases.
Women are much more affected than men by heterosexual contamination: 74% of new cases, almost all cases in which the mode of transmission was documented, have been using this method, against 37.2 % of men. A similar proportion of them was infected through homosexual.
In addition to being a woman, that they are from sub-Saharan Africa also appears to be a risk factor for contracting HIV through heterosexual sex. Nearly half of those infected in this way are of Cameroonian nationality, Congo, Ivory Coast and Congo, against 31% of French nationality.
At diagnosis, 36% of people were in occupation, 39% and 6% inactive unemployed.
In one third of cases, the diagnosis of HIV infection was made after the onset of clinical signs may be associated with an early or late stage of infection. Women were screened in 20% of cases during pregnancy.
The majority of diagnoses related asymptomatic individuals. However, 15% of patients have discovered their HIV status to a non-symptomatic stage AIDS, 12% at the AIDS stage and 8% at the stage of primary infection. Homosexuals are more likely than heterosexuals to discover their condition at the time of primary infection, but less so to discover an asymptomatic stage. Drug users are the category for which screening is most often held at the AIDS stage.
The infection was new in 38.4% of cases, mainly in children under 40 years, homosexuals (58%) and individuals of French origin (50% against 26% for those from sub-Saharan Africa).
Serotyping shows a predominance of HIV-1 from HIV-2, which was found only in 3.2% of those infected. Among the HIV-1 infections, the majority of cases are due to subtype B. This is even more true that those infected are women under the age of 40 years and infected through heterosexual contact. Infections with group O represents only 0.3% of cases documented.
Increased incidence of AIDS through homosexual
After reaching the peak of AIDS in 1994 with nearly 5,800 diagnoses, a dramatic decrease was observed in 1996 and 1997 with the introduction of powerful antiretroviral associations. In 2002, the incidence was close to 1,600 cases in 2002, and the first data collected in 2003 (904 cases) let "fear greater than in previous years under-reporting," the authors fear.
They have in fact, for the first time, found a rise in the incidence of AIDS-related contamination through homosexual compared to previous years, the authors note.
However, new cases registered between 2000 and 2002 are mainly heterosexual AIDS. Moreover, in 2003, a case of AIDS two for a person infected through heterosexual contact, a little more than a quarter way through homosexual and 11% by injection drug use.
As was already mentioned above, the increase in the incidence of cases due to heterosexual transmission is mainly due to a sharp increase in people from sub-Saharan Africa. This upward trend is also observed in the Haitian people.
Half of those with a diagnosis of AIDS was made unaware of their HIV status at diagnosis and 22% knew but had not received antiretroviral treatment before the diagnosis of AIDS. This lack of knowledge was higher among people of sub-Saharan Africa.
