Some characteristics of the HIV epidemic in Morocco

The first case of AIDS in Morocco was declared in 1986 and since then the number of AIDS cases has steadily increased. According to the Ministry of Health, the cumulative number of AIDS cases in December 2002 was 1085. HIV in Morocco is acquired mainly through heterosexual intercourse. Individuals aged between 30 and 39 years and in the regions of Marrakech and Agadir have been the most affected. Monitoring of the trend of the epidemic by sentinel surveillance surveys indicates that Morocco is still a low prevalence zone, since prevalence among pregnant women is less than 1%. The estimated number of HIV-infected people in Morocco is around 15 000. It is not clear why the epidemic here has not evolved as it has in the sub-Saharan countries where it is spreading at an alarming rate. Late introduction of HIV-1 subtype B in Morocco, which is relatively less transmissible, circumcision and reduced risk behaviours of Muslims may explain this. Nonetheless, because prevalence has increased in recent years, unless preventive measures are strengthened, the HIV epidemic will worsen in Morocco

Monitoring HIV through sentinel surveillance in Morocco

HIV sentinel surveillance was performed in five provinces of Morocco in 1993, expanded to 10 provinces in 1996. The activity was done by unlinked anonymous testing procedures. We analysed the data from 1993 to 1999. The groups studied were sexually transmitted infections, clinic attendees, pregnant women and patients with pulmonary tuberculosis. The results show that overall HIV prevalence rate over the whole period in 10 cities was 0.10% [45/44,233]. Casablanca had a significantly high rate with 0.39% [10/2567]. The patients with pulmonary tuberculosis displayed the highest prevalence with 0.36% [9/2530]. These data confirm the assumption that the HIV epidemic is low in Morocco. However, the increase of HIV prevalence lately calls for reinforcing preventive measures to limit its spread
