Contribution of market value chain to the control of African swine fever in Zambia.

African swine fever (ASF) is a worldwide disease of pigs endemic in most sub-Saharan African countries. Zambia has been experiencing outbreaks of ASF for many years because the disease is endemic in the eastern part of the country, with incursion into the central part of Lusaka Province. The latest outbreaks of ASF in Lusaka occurred in 2013 with substantial pig mortalities, loss in trade, and cost of control measures and compensation of affected farmers. The aims of the study were to identify market value chain-related factors that were associated with ASF outbreaks and assess why these outbreaks are becoming frequent despite control measures being put in place. Using a mixed-method design, participants involved in the value chain were purposively sampled. Some pig farmers were included using a respondent-driven technique. Farmers came from Lusaka, Chilanga, Kafue, and Chongwe districts. Other participants included district veterinary officers, veterinary assistants, police officers, and veterinary staff manning veterinary checkpoints, abattoir and processing plant managers, meat inspectors, market chairpersons, and traders. Semi-structured questionnaires, in-depth interviews, and direct observations were used to collect data to come up with narrations, tables, and flow charts. In assessing the contribution of the value chain in ASF, aspects of ASF screening, market availability and procedures, knowledge on ASF transmission, occurrence of ASF outbreak, and regulation of pig movement were investigated. Despite government ASF control measures being applied, the following were noted: (1) low awareness levels of ASF transmission among pig farmers and traders; (2) only 50% of farmers had their animals screened for ASF before sale; (3) all the markets did not have the pork inspected; (4) laxity in enforcing livestock movement control because of inadequate police and veterinary staff manning checkpoints; (5) lack of enforcement of meat inspection and food safety regulations at pig markets; and (6) inadequate and bureaucratic ASF screening. Improving biosecurity; sensitizing farmers, traders, and all stakeholders in the pig value chain on ASF prevention and control; reinforcement of staff at checkpoints; and regulation of pig markets are some of the ways in which future outbreaks can be prevented.

Characterisation of Vibrio cholerae isolates from the 2009, 2010 and 2016 cholera outbreaks in Lusaka province, Zambia.

INTRODUCTION: In 2009 and 2010, more than 6,000 cholera cases were recorded during these outbreaks with more than 80% of cases recorded in Lusaka province. After a five-year break, in 2016 an outbreak occurred in Lusaka, causing more than 1,000 cases of cholera. This study will strengthen the epidemiological information on the changing characteristics of the cholera outbreaks, for treatment, prevention and control of the disease. METHODS: This was a laboratory-based descriptive cross-sectional study conducted at the University Teaching Hospital in Lusaka, Zambia. A total of 83 V. cholerae O1 isolates were characterised by biochemical testing, serotyping, antimicrobial susceptibility testing, and macrorestriction analysis using Pulsed-Field Gel Electrophoresis. RESULTS: Macrorestriction analysis of the isolates demonstrated high genetic diversity among the isolates with 16 different patterns. The largest pattern comprised 9 isolates while the smallest one had 1 isolate. 2009 and 2010 isolates were highly resistant to nalidixic acid and cotrimoxazole, but highly sensitive to azithromycin and ampicillin. Of the fifty-two isolates from the 2016 cholera outbreak, 90% (47) were sensitive to cotrimoxazole, 94% (49) to tetracycline, and 98% (51) to azithromycin, while 98% (51) were resistant to nalidixic acid and 31(60%) to ampicillin. CONCLUSION: macrorestriction analysis demonstrated high genetic diversity among the V. cholerae O1 strains, suggesting that these isolates were probably not from a similar source. This study also revealed the emergence of multidrug resistance among the 2016 V. cholerae outbreak isolates but were susceptible to cotrimoxazole, tetracycline, and azithromycin, which can be used for treatment of the cholera cases.

Herbal medicine use among pregnant women attending antenatal clinics in Lusaka Province, Zambia: A cross-sectional, multicentre study.

BACKGROUND AND PURPOSE: The study of herbal medicine (HM) use which is related to maternal health, a public health priority in many sub-Saharan African countries including Zambia, has been limited. Accordingly, we aimed to determine the prevalence and patterns of HM use during pregnancy in Lusaka Province, Zambia. MATERIALS AND METHODS: A survey-based (interviewer-administered), cross-sectional, multicentre study was conducted in 446 adult pregnant women attending antenatal clinics in June/July 2019. RESULTS: Overall, 57.8% of participants reported using HM during their current pregnancy, with a mean of 2.0 ± 1.5 remedies/woman. Logistic regression analysis showed that HM use was significantly associated with HM use in prior pregnancies (p < 0.001) and willingness to use HM in the future (p < 0.001). The most commonly used herbs were lemon for nausea/vomiting and common cold, soybean to boost energy, ginger for common cold and nausea/vomiting, and Aloe vera for skin care. The perceived safety of HM (37.6%) and its complementary action with conventional medicines (35.3%) were the main reasons for HM use. CONCLUSION: HM use among pregnant women attending antenatal clinics in Lusaka Province, Zambia is common, and a wide range of herbs is used.

"Back to Eden": An explorative qualitative study on traditional medicine use during pregnancy among selected women in Lusaka Province, Zambia.

BACKGROUND AND PURPOSE: No qualitative study on traditional medicine use among Zambian pregnant women has ever been conducted. Accordingly, this study was performed to explore the perceptions, motivations and experiences of Zambian women with regard to traditional medicine use during pregnancy. MATERIALS AND METHODS: In-depth, semi-structured interviews were conducted in June/July 2019 with 8 adult women residing in Lusaka, Zambia, who used traditional remedies during their pregnancies, and who were recruited through purposive and snowball sampling. RESULTS: Reported reasons behind traditional medicine use during pregnancy included labour induction, prevention of childbirth complications in case of sexual infidelity by either spouse, and prevention and/or treatment of anaemia. In addition, family members and faith leaders played an important role in influencing traditional medicine use. CONCLUSION: Multiple, interconnecting factors influence traditional medicine use among pregnant women in Lusaka, Zambia. Traditional medicine use during pregnancy will likely continue to be widespread across Zambia.

Diet satisfaction and associated factors among adult surgical orthopaedic inpatients at a teaching hospital in Lusaka province, Zambia; a hospital-based cross-sectional study.

BACKGROUND: Poor quality of food services in hospital contributes to low diet satisfaction among inpatients in both developed and developing countries. However, there is paucity of literature on diet satisfaction in health care facilities in the sub-Saharan region and in particular Zambia. Therefore, this study sought to assess levels of diet satisfaction among adult surgical orthopaedic inpatients at a teaching hospital in Lusaka province, Zambia. METHODS: A hospital-based cross-sectional study was conducted over a period of three months. Comprehensive sampling was used to select 98 study participants. A researcher-administered questionnaire adapted from a similar study was used to collect data. The instrument used in this study had 9 aspects of satisfaction. Descriptive statistics such as frequencies, percentages, means and standard deviations were used to analyze the data. Chi-square test was used to test for associations between categorical data. A p-value of less than 0.05 was considered to be statistically significant. RESULTS: In this study, 64.3% of surgical orthopaedic inpatients were not satisfied with overall quality of hospital food. In addition, 76.5, 96.9, 65.3 and 71.4% of the patients were not satisfied with type, variety, appearance and taste of hospital food respectively. However, patients who were satisfied with portion size, temperature and time of meal distribution were 67.3, 94.9 and 56.1% respectively. There was no significant association between variables of age, sex, education level, marital status, monthly income, days in hospital and overall satisfaction (p > 0.05). CONCLUSION: Low diet satisfaction is a global problem associated with poor quality of hospital meals. Although the majority of surgical orthopaedic inpatients were not satisfied with more than half of the dimensions of diet satisfaction, they were satisfied with aspects of portion size, temperature and time of meal distribution. Therefore, an assessment of diet satisfaction can inform hospital administrators and policy makers on the deficiencies in hospital diets and thereby help improve quality of meals.
