Data Appraisal
Estimates of Sampling Error The methods, tools and assumptions used to estimate the burden of HIV/AIDS in Nigeria are based on the recommendations made by the UNAIDS Reference Group in estimates, modelling and projections. The UNAIDS Reference Group is a technical working group made up of experts in epidemiology, modelling and statistics, which advises UNAIDS on the best methods and tools to be used to estimate national figures for HIV and AIDS. These methods and tools are revised regularly and improvements have been made since 2003. The Epidemic Projection Package (EPP 2007) was used to estimate and project adult HIV prevalence and the burden of infection in the country from the surveillance data obtained from ANC clients. The software uses inputs such as base population, sex ratio and urban - rural infection ratio. The resulting national estimated adult HIV prevalence was then transferred to a demographic package, Spectrum 3, modelling software for demographic projections to calculate the number of people infected and other parameters, such as AIDS cases, AIDS deaths and AIDS orphans. The basic data used to estimate HIV prevalence at the national level was the data collected on pregnant women attending ANC clinics through regular surveys which have been conducted in Nigeria since 1991. In the recent past (since 1999), these surveys have been conducted every 2 years. One of the main factors affecting the results of this system is the level of attendance of pregnant women in the ANC clinics. In Nigeria, it has been estimated that ANC clinics cover about 60% of the pregnant women, and there are extreme variations in the different States and among social classes. | |
