title: The usefulness of defined clinical features in the diagnosis of HIV/AIDS infection in Sierra Leone.
abstract: Sierra Leone ranks at the bottom of the global World Bank Development Index based on multiple health and economic indices and lacks the resources to purchase HIV diagnostic kits. Our study has defined some common clinical features presenting HIV infection that could form clinical algorithms for the diagnosis and recognition of HIV infection by health workers in Sierra Leone. In a private clinic in Freetown, Sierra Leone, West Africa, 106 out of a total of 124 patients presenting with various symptoms and strong clinical suspicion of HIV infection within a two-year period (1999 and 2000), were deemed positive by two different ELISA tests. The prevalence of HIV infection seen in this private clinic in Freetown in 2000 was 14.89% as compared to 9.25% in 1999. The positive predictive value of our clinical diagnosis of HIV/AIDS infection was 85.5%. The male:female ratio of the patients in our series was 1:1.9, with a mean age of 39 years for males and 28 years for females. HIV infection was found in a cross-section of the population that we examined. Heterosexual contact appeared to be the major mode of transmission amongst our patients and there seemed to be a significant epidemiological risk of HIV infection amongst those who traveled to other countries in the West African sub region. Common clinical features in decreasing frequency were fever (92.5%), weight loss (84.1%), lymphadenopathy (78.3%), cough (48.1%), diarrhea (37.7%), candidiasis (32.1%) and body aches (30.1%).
