| 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 |
| prevalence of hiv-1 and hiv-2/htlv-iv infections in luanda and cabinda, angola. | a seroepidemiological study of human immune deficiency virus type 1 (hiv-1) and hiv-2/human t-lymphotropic virus type iv (hiv-2/htlv-iv) infections was performed in angola in october 1986. until then five cases of acquired immune deficiency syndrome (aids) had been registered in angola. during this study, another three cases with clinical aids were found and confirmed by hiv-1 serology. a total of 1,215 sera from groups of healthy persons and patients were tested for hiv-1 and hiv-2/htlv-iv anti ... | 1988 | 2905739 |
| 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 |
| infectious aetiology of jaundice among pregnant women in angola. | the contribution of viral hepatitis, human immunodeficiency virus (hiv) infection and malaria to jaundice among pregnant women in luanda, angola, was studied. 20 pregnant women with jaundice (cases) were identified in 2 large maternity hospitals and compared with 40 pregnant women without jaundice (controls). among the cases 6 patients died, whereas no death occurred in the control group (p < 0.001). five spontaneous abortions and 6 stillbirths were also noted among the cases, implying foetal lo ... | 2003 | 12953953 |
| high genetic diversity of human immunodeficiency virus type 1 in angola. | to investigate which hiv-1 genetic forms are circulating in angola, we have determined the gag and/or env genotypes of 48 isolates from patients living in cabinda and luanda provinces. the following subtypes were identified: a1 (18 samples, 38%), c (7, 15%), h (5, 10%), j (3, 6%), g (2, 4%), a2 (2, 4%), f1 (1, 2%), and d (1, 2%). the env gene fragment was untypable in one sample. discordant subtype classifications in the gag and env genes were found in eight (17%) samples. there were six differe ... | 2005 | 15943573 |
| 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 |
| otorhinolaryngological findings and hearing in hiv-positive and hiv-negative children in a developing country. | the otorhinolaryngological (orl) manifestations of human immunodeficiency virus (hiv) are common, but remain poorly characterized among children of sub-saharan africa, where 90% of new pediatric infections occur. our objective was to compare orl findings and hearing in hiv-positive and -negative children of luanda, angola, using a comparative study of 78 outpatients from the hiv polyclinic and of 78 age- and sex-matched controls in a pediatric hospital with interview, general and orl examination ... | 2011 | 21437696 |
| prevalence of human immunodeficiency virus, hepatitis c virus, hepatitis b virus and syphilis among individuals attending anonymous testing for hiv in luanda, angola. | human immunodeficiency virus (hiv), hepatitis b virus (hbv), hepatitis c virus (hcv) and syphilis remain major infections around the world. in angola there are about 166 000 individuals living with hiv, representing a prevalence of 1.98% in adults between 15 and 49 years of age. in a 2003 study in luanda, 4.5% of pregnant women had antibodies to hiv and 8.1% to hbv, and 5.4% were infected with treponema pallidum. objectives. the aim of this study was to determine the prevalence of hiv-1 and 2, h ... | 2013 | 23472697 |
