| childhood malaria in a region of unstable transmission and high human immunodeficiency virus prevalence. | malaria and hiv are important pediatric problems in sub-saharan africa. it is uncertain how hiv-related immunosuppression and malaria interact in children. we aimed to describe associations among hiv status, presentation and outcome from malaria in children from hlabisa district, kwazulu-natal, south africa, a region of high hiv prevalence and unstable plasmodium falciparum transmission. | 2003 | 14688565 |
| gb virus type c coinfection in hiv-infected african mothers and their infants, kwazulu natal, south africa. | gb virus type c (gbv-c) infection was studied in a convenience sample of 75 antiretroviral (art)-naive african mothers with human immunodeficiency virus infection and their infants. gbv-c rna was extracted from serum and amplified by reverse-transcriptase polymerase chain reaction. twenty-seven (36%) of these 75 hiv-infected women tested positive for gbv-c rna. to study transmission dynamics, we chose a random subsample of 20 of these women and their infants. in this cohort, there was evidence o ... | 2004 | 14727212 |
| reduction in prevalence of invasive cervical cancer in kwazulu-natal, south africa: impact of the human immunodeficiency virus epidemic. | the bulk of the human immunodeficiency virus (hiv) pandemic continues to ravage the developing world, especially sub-saharan countries. the hiv seroprevalence among women with invasive cervical cancer varies in different parts of the world. a comparison of women with cervical cancer was undertaken for epidemiologic data in the province of kwazulu-natal, south africa, which has the highest hiv prevalence. the two time periods of study were 1999 and 2003. the aim was to determine the trends of pre ... | 2006 | 16803482 |
