Chapter 4The Demographic Impact of HIV and AIDSin MozambiqueEpidemiological surveillanceIn Mozambique, there are two forms of notificationof Sexually Transmitted Infections (STI) andAcquired Immune Deficiency Syndrome (AIDS),namely: passive (in health units), and active(Sentinel Surveillance of HIV in Pregnant Women)(MISAU-PNC STD/AIDS, 2001).In the passive form, all health units should notify,every month, cases of STI/AIDS to district level.The district notifies to the provincial level, whichfinally reports to the PNC-STD/AIDS in Maputo.(Barreto et al, 2002). However, comparing the totalnumber of AIDS cases notified this way, with the totalexpected, according to estimates obtained throughthe active form, one notes that the system of passivenotification catches less than 20% of the real numberof AIDS cases.For this reason, for programmatic purposes, theprevalence estimates obtained through the activemeans are used. This data is gathered from pregnantwomen who present themselves consecutively fortheir first ante-natal consultation. These rates areconsidered as representative of the adult populationaged 15-49, and are thus used as a basis to estimatethe provincial and national HIV prevalence rates, andthe demographic impact of HIV and AIDS on thecountry.In the 2001, 2002 and 2004 rounds, theEpidemiological Surveillance (EV) systemoperated with 36 sentinel sites. Table 4.1and Map 4.1 show the evolution of theprovincial, regional and national weightedHIV prevalence rates over the period 2001-2004. As can be observed, in general thesouthern and northern regions show a risingtrend of the epidemic, although differencesmay be noted in the pace of growth betweenthe various provinces. In the south thesharpest growth was observed in Maputo cityand province; the weighted rate inInhambane also grew, due to the increaseTable 4.1Map 4.1Maputo20.7%Tete16.6%Manica19.7%Gaza19.9%Sofala26.5%Inhambane11.7%Maputo city20.7%HIV prevalence rate2004, 15-49 yearsNiassa11.1%Zambézia18.4%Cabo Delgado8.6%Nampula9.2%Below 10%Between 10% & 20%Above 20%Source: Report on revision of the HIV epidemiological surveillance dataround,2004 (INE/MISAU)Comparison of provincial, regional and nationalweighted HIV prevalence rates, 2001-2004 (%)Province 2001 2002 2004 Region 2001 2002 2004Maputo city 15.5 17.3 20.7 South 14.4 14.8 18.1Maputo province 14.9 17.4 20.7Gaza 19.4 16.4 19.9Inhambane 7.9 8.6 11.7Zambézia 15.4 12.5 18.4 Centre 16.8 16.7 20.4Sofala 18.7 26.5 26.5Manica 18.8 19.0 19.7Tete 16.7 14.2 16.6Niassa 5.9 11.1 11.1 North 6.8 8.4 9.3Nampula 7.9 8.1 9.2Cabo Delgado 5.0 7.5 8.6National 13.0 13.6 16.221
