RESUMO
A 26-year-old black African woman presented with an acute onset of hemiparesis and visual symptoms. This had been preceded several months by symptoms which were apparently psychiatric in nature. She had no apparent risk for cerebrovascular disease. Neurological evaluation revealed a striking burden of cerebrovascular disease for her age, including the rare stroke syndrome of basilar artery occlusion. Human immunodeficiency virus (HIV) infection was identified during clinical assessment. This was judged to be perinatally acquired, as there was no history of sexual debut or blood transfusion; her mother was taking antiretroviral therapy and she had facial planar warts and underlying bronchiectasis. Therefore, it has been concluded that presentation of stroke should prompt HIV testing in young people and perinatally-acquired infection can present in adulthood.

OBJECTIVE: To determine the prevalence of HSV-2 infections in a population of blood donors. DESIGN: Cross sectional study. SETTING: Harare Blood Transfusion Service (BTS) Centre. SUBJECTS: 314 serum specimens of voluntary blood donors. MAIN OUTCOME MEASURES: HSV-2 sero-prevalence. RESULTS: The median age (Q1, Q3) of the blood donors was 18 (17,27) years and 65% of them were males. HSV-2 infection was detected in 29 (9.7%) of the 299 specimens that were analyzed. There was a strong association between age of blood donors and HSV-2 seropositivity (p < 0.001). Older blood donors tended to be positive while younger donors tended to be negative for HSV-2 antibodies. Though not as strong, there was also an association between HSV-2 and HIV seropositivity (p = 0.048). CONCLUSION: The prevalence of HSV-2 infections in blood donors in Harare is high, considering the nature of the population studied. Therefore, the testing for HSV-2 in the serum of prospective blood donors should be included in the screening profiles used at the BTS centre in Harare, Zimbabwe to improve blood and blood products.
