| a study of seroprevalence of hiv-1 and hiv-2 in six provinces of people's republic of angola: clues to the spread of hiv infection. | a seroepidemiological study was carried out to determine the distribution of the human immunodeficiency viruses type 1 (hiv-1) and type 2 (hiv-2) in the people's republic of angola, where hiv-2 existence was previously unknown and hiv-1 seropositivity was only reported to be present in luanda and cabinda. a total of 1,695 serum samples were obtained from healthy persons (control group) and from a group of patients in the provinces of zaire (13), lunda-norte (l.n.) (749), luanda (556), huambo (15 ... | 1990 | 2366148 |
| angola launches rejuvenated programme. | angola has been at war almost continuously since the early 1960s. over the past few years, large parts of the country have been under the control of unita and thus beyond the reach of government health services. the first reported case of aids in angola was identified in late 1985. by june 3, 1995, 993 cases had been confirmed. of these cases, women outnumber men by 13 to 10, and most cases are aged 20-39 years. officials realize, however, that the true numbers are actually higher. the wor ... | 1996 | 12290770 |
| highly divergent subtypes and new recombinant forms prevail in the hiv/aids epidemic in angola: new insights into the origins of the aids pandemic. | angola, located in south-western africa, has a remarkably low hiv/aids prevalence in the adult population (3.7%). it is bordered in the north by the democratic republic of congo (drc) and republic of congo that are at the origin of human hiv-1 infections. it is, therefore, likely that hiv-1 strains circulating in angola are genetically diverse and representative of the origin of the hiv/aids epidemic. the aim of this work was to investigate in detail the genetic diversity and molecular epidemiol ... | 2009 | 18562253 |
