Background & Aims: Immunodeficiency virus (HIV) may lead to acquired immunodeficiency syndrome (AIDS) in human. Parasites are one of the most important causes of infectious diseases in patients with AIDS. The prevalence of these parasites varies based on the condition of host’s immune system and the stage of disease (HIV/AIDS). To compare the prevalence of opportunistic intestinal parasites a c...
BACKGROUND We address the research questions: (i) what proportion of new HIV infections is transmitted from people who are (a) undiagnosed, (b) in primary HIV infection (PHI), (c) on antiretroviral therapy?; and (ii) what is the expected epidemiological impact of (a) increasing the proportion of newly acquired HIV infections receiving early treatment, and (b) increasing HIV testing rates? MET...
BACKGROUND Knowledge of the number of recent HIV infections is important for epidemiologic surveillance. Over the past decade approaches have been developed to estimate this number by testing HIV-seropositive specimens with assays that discriminate the lower concentration and avidity of HIV antibodies in early infection. We have investigated whether this "recency" information can also be gained...
A new anti-human immunodeficiency virus type 1 and 2 (anti-HIV 1 and 2) test is described. It uses recombinant p24 and peptides covering gp32, gp41, and gp120 to identify HIV-1 and HIV-2 infections. This test has been shown to be specific (99.5%) and sensitive (99.8%). In this respect, the assay was equal or superior to anti-HIV 1 and 2 tests run as references. The test was able to discriminate...
In the United States, approximately 25% of the 40,000 new human immunodeficiency virus (HIV) infections each year are secondary to injection drug use. Worldwide, there are an estimated 12.6 million injection drug users, and 10% of HIV infections (420,000 infections in 2003) are associated with this practice. Buprenorphine is a new medication used to treat opioid dependence that shows promise fo...
Background and Aim: HBV (hepatitis B virus), HCV (hepatitis C virus) and HIV (human immunodeficiency virus) are among important infectious agents in prisoners. Intravenous addicts in prisons are one of the high risk groups and are more susceptible to such viral infections. There are many reports suggesting that prevalence of HBV, HCV and HIV is higher in prisoners. The present study was carried...
BACKGROUND Guangxi has become one of the provinces with the most severe HIV-1 epidemic in China, where heterosexual contact is the dominant transmission route. However, data of acute HIV infections and HIV incidence among female sex workers (FSWs) from low-grade venues are scant. METHODS A cross-sectional survey was performed among FSWs from low-grade venues in Guangxi. HIV antibody screening...

We systematically evaluated multiple and recombinant infections in an HIV-infected population selected for vaccine trials. Seventy-nine HIV-1 infected persons in a clinical cohort study in Rio de Janeiro, Brazil, were evaluated for 1 year. A combination of molecular screening assays and DNA sequencing showed 3 dual infections (3.8%), 6 recombinant infections (7.6%), and 70 (88.6%) infections in...
Human papillomavirus (HPV) is an etiologic agent for both oropharyngeal and cervical cancers, yet little is known about the interrelationship between oral and cervical HPV infections. Therefore, we compared the prevalences and type distributions of oral and cervical HPV infections and evaluated infection concordance in a cross-sectional study within the Women's Interagency HIV Study cohort. Ora...
