ABSTRACT
<p><b>OBJECTIVE</b>To determine the pattern, challenges and correlates of condom use among Nigerians living with HIV Infection.</p><p><b>METHODS</b>A cross sectional questionnaire study among HIV positive adults attending an HIV treatment centre in Lagos, Nigeria. Data entry and analysis were done with Epi-info version 3.5.1.</p><p><b>RESULTS</b>The mean age of respondents was 35 (SD=7.7; range: 17-58 years) and mean age at sexual debut was 20 years old (range: 7-37 years). Majority were women (66.6%), had at least secondary school education(91.1%), married (68.2%)), on ART (50.7%) and knew their partners HIV status(60.9%). The rate of condom use at last sex act was 65.9%, but only 48.8% used condom consistently. Factors associated with condom use were male gender (OR=2.43, CI=1.35-4.33, P=0.002), less than secondary school education (OR=3.12, CI=1.04-9.28, P=0.05) and Not knowing partner's HIV status (OR=1.90, CI=1.04-3.80, P=0.04). Refusal to use condom (28.4%) were as a result of pregnancy intention, undesirability of condom in marriage and decreased sexual pleasure.</p><p><b>CONCLUSION</b>There is low consistent condom use rate of 48.8% among this cohort despite their exposure to behavioural change messages. A review of the present counselling strategy and combination prevention is therefore advocated.</p>
ABSTRACT
This study aimed at characterizing the phenotypic and toxigenic status of circulating strains of cholera during outbreaks in Nigeria, employing molecular typing techniques. Two hundred and one samples of rectal swabs, stool, vomitus, water (from the well, borehole, sachet, stream, and tap) and disinfectants (sodium hypochlorite) were collected from three states in the country. The samples were inoculated on thiosulphate-citrate bile salt-sucrose (TCBS), Cary-Blair transport medium and smeared on glass slides for direct examination. The Vibrio cholerae isolates were serotyped, biotyped, and characterized using PCR of the cytotoxin gene A (ctxA), wbeO1, and wbfO139 gene primer. Of the 201 samples screened, 96 were positive for V. cholerae O1 (48%), with 69 (72%) positive for ctxA gene. The results from this study showed that the circulating strains of cholera in Nigeria were of Ogawa serotype, also observed in other outbreaks in Nigeria (1991, 1992, and 1996). However, the strains were of the Classical biotype and were mainly (72%) ctxA gene-positive. This current investigation has confirmed the production of cholera toxin by the circulating strains, and this could be harnessed for possible cholera vaccine production in Nigeria.
