Clinical Performance Validation of 4 Point-of-Care Cervical Cancer Screening Tests in HIV-Infected Women in Zambia

The effect of seasonal variation on anthrax epidemiology in the upper Zambezi floodplain of western Zambia

Abstract: Anthrax has become endemic throughout the upper Zambezi floodplain located in the Western Province of Zambia over the recent years. To date, no comprehensive study has been carried out to determine whether recurrence of anthrax outbreaks may be linked to differences in precipitation and human activities. Retrospective data for the period 1999 to 2007 showed that a total of 1,216 bovine cases of anthrax were reported. During the same period, 1,790 human anthrax cases and a corresponding case fatality rate of 4.63% (83/1,790) was documented in the upper Zambezi floodplain. Occurrence of human cases was highly correlated with cattle outbreaks (r = 0.94, p < 0.001). Differences in precipitation were significantly associated with the occurrence of anthrax outbreaks (χ2 = 4.75, p < 0.03), indicating that the likelihood of outbreaks occurring was higher during the dry months when human occupancy of the floodplain was greater compared to the flooding months when people and livestock moved out of this region. Human dependency on the floodplain was shown to significantly influence the epidemiology of anthrax in the upper Zambezi floodplain of western Zambia. Methods for mitigating anthrax outbreaks by disrupting the cycle of transmission are herein highlighted.

Sexual behaviour and sexually transmitted diseases among young men in Zambia.

Abstract: Sexually transmitted diseases (STDs) are an increasing public health problem in Zambia. About 200 000 cases of STDs are treated annually in the formal health sector. Young people are the most affected by STDs. High-risk sexual behaviour has been identified as the major risk factor for STDs among young people. We conducted interviews and focus group discussions with a purposely selected sample of 126 young men aged between 16 and 26 in Chiawa, rural Zambia. The aim of the interviews and focus group discussions was to explore views about sexual practices and attitudes towards STD. Fifty-eight (59%) young men reported having had pre-marital or extra-marital sexual partners during the past year. The maximum number was five partners for six individuals. Forty-two (43%) had pre-marital or extra-marital sexual partners at the time of the interviews. Focus group discussions revealed that perceptions of manhood encouraged multiple sexual relationships. Twenty-two (23%) reported having suffered from an STD in the past. Seventy-nine (81%) said they were likely to inform their sexual partners if they had an STD. Although condoms were believed to give protection against STDs by the majority (94%), only 6% said they always used condoms. The data suggest that condoms were perceived to affect male potency. These results show that STDs, multiple sexual relationships and unprotected sex are common among the young men of Chiawa. Perceptions that emphasize manhood are widespread and these may negatively affect efforts for positive behavioural change. Health messages that target the young men should take into account the local perceptions and values that seem to sustain risky sexual behaviour.

How HIV/AIDS scale-up has impacted on non-HIV priority services in Zambia

Abstract: Background: Much of the debate as to whether or not the scaling up of HIV service delivery in Africa benefits non-HIV priority services has focused on the use of nationally aggregated data. This paper analyses and presents routine health facility record data to show trend correlations across priority services. Methods: Review of district office and health facility client records for 39 health facilities in three districts of Zambia, covering four consecutive years (2004-07). Intra-facility analyses were conducted, service and coverage trends assessed and rank correlations between services measured to compare service trends within facilities. Results: VCT, ART and PMTCT client numbers and coverage levels increased rapidly. There were some strong positive correlations in trends within facilities between reproductive health services (family planning and antenatal care) and ART and PMTCT, with Spearman rank correlations ranging from 0.33 to 0.83. Childhood immunisation coverage also increased. Stock-outs of important drugs for non-HIV priority services were significantly more frequent than were stock-outs of antiretroviral drugs. Conclusions: The analysis shows scale-up in reproductive health service numbers in the same facilities where HIV services were scaling up. While district childhood immunisations increased overall, this did not necessarily occur in facility catchment areas where HIV service scale-up occurred. The paper demonstrates an approach for comparing correlation trends across different services, using routine health facility information. Larger samples and explanatory studies are needed to understand the client, facility and health systems factors that contribute to positive and negative synergies between priority services.
