Anaphylaxis due to liposomal amphotericin (AmBisome)

Letters to the Editor study population (12.75%).Thus we can con- firm that the presence of vaginal and cervical ulcers may be considered an additional risk factor for HIV transmission.Although our study was performed on sera belonging to women considered at risk for HIV infections, only 2% of them were certainly infected by HIV-1 and none was infected by HIV-2.This percentage is consistent with another study on an analogous sample of 100 women in February 1993 (data not shown).During the last 10 years, the war in Angola has greatly limited movement of people between Luanda province and the bordering provinces of Congo, Zaire and Zambia.Probably the low prevalence of HIV in Luanda is due to the partial isolation of the city during the spread of HIV pandemic in Sub Sahara Africa.
