rates were higher among pregnant women (42.2%) than female VCT clients
(30.9%) (P<0.001). The same trend was observed in age groups 15-19 years
(27% vs 9%) and 20-29 years (44.7% vs 31.7%). Single women had higher HIV+
rates than married women both among pregnant women (42.7% vs 34.9%) and
among female VCT clients (31.5% vs 25.7%). Women without formal education or
who completed only primary school were more likely to be HIV+ than those who
completed secondary or those with tertiary education (pregnant women: 45.9%,
40.8%, 29.2%; VCT clients: 54.7%, 34.2%, and 16.2%, test for trend, P<0.001).
Women with a regular job were more HIV+ than women without a job both for
pregnant women (46.2% vs 39.8%) and VCT clients (32.2% vs 29.4%).
Conclusions: Although HIV prevalence estimates using pregnant women were
higher than those using female VCT clients, both programs yield data that show
similar trends. In Botswana, HIV infection among women is associated with age,
single status, education, and disposable income through employment.

Directorate of Health for Epidemiology and Environmental Health, Ministry of
Health, Maputo, Mozambique
Background: Previous to 2000, Mozambique had only four sentinel sites (SS).
None were located in the northern region, nor in rural areas. Realizing these
shortcomings, in 2000, the Ministry of Health decided to increase the number of
sites to 22 and distribute them across all eleven provinces in both rural and urban
areas to improve the national picture of the epidemic.
Methods: Sentinel HIV surveillance in Mozambique uses the anonymous, unlinked methodology and is carried out in antenatal clinics. In 2000, quality control
was instituted at the central level, and supervisory visits increased. Data presented here are from 20 sites, the remaining two were excluded because of operational and quality control problems. Province-specific prevalence rates were
calculated by assigning each district to a SS, using that site's prevalence, and
weighting by district population size. Assignment of districts to SSs was accomplished on the basis of social, economic, and cultural similarity between the SS
and target districts.
Results: Prevalence rates varied a great deal from province to province. The
lowest rates occurred in the northern region ranging from 5 to 7%. In the southern region, rates ranged from 10 to 16%. Finally the highest rates were in the
central region, ranging from 13 to 21%, with three of the four provinces showing
prevalence around 20%.
Conclusions: New data from the sentinel surveillance of HIV in Mozambique underscore the need to prioritize responses to the epidemic in different geographical
areas. While prevention should still constitute a major effort in all areas, impact
reduction needs to be considered more strongly in areas of higher prevalence,
where the epidemic is probably of longer duration. Prevalence rates especially in
the central and also in the southern regions call for increased resource allocation
for care and support as well as other impact reduction interventions.

A. Gaye-Diallo', I. Ndoye2, S. Mboup1. 'Bacteriology-Virology Laboratory
Dakar, Senegal; 2NACP, Dakar, Senegal
Background: This study focuses on the course of the HIV epidemics in four urban
areas Senegal. The prevalence of HIV1 and HIV2 has been evaluated through the
National HIV Sentinel Surveillance Program since 1989.
Methods: The HIV sentinel surveillance program includes regional laboratories
collecting sera in sentinel sites and Virology Reference Laboratory of Le Dantec Hospital. Surveys are regularly done among pregnant women in four regions
(Dakar, Kaolack, Ziguinchor and Thies) since 1989. A first screening of collected
sera carried out at the regional laboratory and samples are sent to the reference
laboratory for confirmation or discrimination and quality control. Basic epidemiologic measures of frequency are calculated with 95% CI and Mantel-Haenszel

technique, is explored.
Results: Since 1989 HIV1 and HIV2 prevalence were stable (c2trend=0.3, p=0.6)
and (c2trend=0.7, p=0.4) among pregnant women in Dakar. Reversal progression trends have been observed since 1996. In 2001, the prevalence was 0.7%.
In Kaolack, the higher prevalence areas HIV2 prevalence first stable, and then
tended to decrease since 1999 whereas HIV1 increased. The HIV infection trend
decreased with a prevalence of 0.8% in 2001.

Conclusions: HIV1 prevalence increased significantly and the HIV2 prevalence
was stable among pregnant women, The prevalence of HIV among pregnant
women was maintained between 0.5 to 1.6% since the beginning of HIV infection in sentinel sites. Combined behavioral and biological survey among specific
groups is undertaken to provide additional knowledge about HIV infection levels
and risk behaviors to complement existing biological and behavioral surveillance
activities.

WePeC6098 New diagnoses of HIV infection since 2000:
Implications for primary prevention amongst gay
and bisexual men in England and Wales
N.D. Macdonald, J.Y. Mortimer, K.A. Fenton. PHLS HIV Reporting Centre at
CDSC, London, United Kingdom
Background: Surveillance of new diagnoses of HIV infections in the United Kingdom (UK) has recently been enhanced by the introduction of HIV reporting from
Clinicians, who have been asked to report all adults diagnosed since January
2000. Prior to this, surveillance of new diagnoses has been through laboratory
reports, and the extent of epidemiological information available to Microbiologists
is often limited. With the decline in the number of AIDS cases reported since the
introduction of HAART, the opportunity has been taken to request additional information from Clinicians. This report presents results from this enhanced surveillance relevant to primary HIV prevention amongst gay and bisexual men in England and Wales.
Methods: Data on individuals exposed to HIV through sex between men and diagnosed since January 2000 in England and Wales and reported by December
2001 were analysed.
Results: A total of 2393 individuals exposed to HIV through sex between men
were diagnosed and reported between January 2000 and December 2001. Laboratory reports were received for 83%, Clinician reports 57%, with 40% both.
Median age at diagnosis was 34 years (IQR 29-40). Country of probable infection
was reported for 41%, for which 84% of whom it was the UK. Country of birth
was reported for 53%, for 71% of whom it was the UK. 80% (1132/1419) were
reported as either infected or born in the UK. Ethnicity was reported for 73%, of
which 87% were white. A CD4 count around time of diagnosis was reported for
52%, with a median count of 355 cells/Rl (IQR 144-563). A previous HIV negative
test was reported for 26% with 18% within 3 years of testing positive.
Conclusions: Despite initial limitations in coverage and completeness of information this enhanced surveillance can identify groups within the potential remit
of national primary prevention, whose characteristics, particularly where recently
infected, can improve targeting of prevention efforts.

SIDA), Plaza de Espaha 6, CIPS, Plaza de Espaia, 6, Alicante - 03010,
Alicante, Spain; 2CIPS of Castellon, Castellon, Spain
Background: The aim of this study was to know the HIV-related risk practices
which tell the users with 60 or more years, and their relation with the prevalence
of the HIV infection.
Methods: Descriptive study of the users who attended for the first time the CIPS
of Alicante from 1987 to 2001 and are 60 years old or more, analysing sociodemographic variables (age, sex), main risk practice and HIV as a result variable. We
included the data in a Dbaselllplus database and analysed it with the statistical
program Epilnfo-Vl.
Results: The number of clinical-epidemiological stories, which we analysed, was
151. The 72.8% of the users were male. The 54.3% were 60 to 64 years old and
the 27.8% were 65-70. The 60.3% attended the centre because of heterosexual
relations, being these users male in the 76.9% and females in the 23.1%. The
11.9% attended because of living together with HIV-positive persons, without significant genre differences in this group; the 11.9% were men who have sex with
men (MSM) and the 14.6% attended for another reasons, without genre differences. HIV status: 139 (92.4%) were tested for HIV antibodies and 10 (7.2%)
turned out to be positive, 8 (7.8%) males and 2 (4.9%) females. In the positive
group, 2 men reported Injecting Drug Use (IDU), 3 men sexual relation with other
men, 3 male heterosexual relation and the 2 women presented seropositive sexual partner (one of them IDU).

Conclusions: In spite of the little representation of this age group in the total number of the CIPS' users, (about 1%), we think the seropositivity percentage (7.8%)
of those who attended, not been representative, is important and we believe that
it must be a line of work to do approach information about the HIV infection and
STD, as well as about the resource.
