Background: Antimicrobial resistance (AMR) is a global health challenge that has escalated due to the inappropriate use of antimicrobials in humans, animals, and the environment. Developing and implementing strategies to reduce and combat AMR is critical. Purpose: This study aimed to highlight some global strategies that can be implemented to address AMR using a One Health approach. Methods: This study employed a narrative review design that included studies published from January 2002 to July 2023. The study searched for literature on AMR and antimicrobial stewardship (AMS) in PubMed and Google Scholar using the 2020 PRISMA guidelines. Results: This study reveals that AMR remains a significant global public health problem. Its severity has been markedly exacerbated by inappropriate use of antimicrobials in humans, animals, and the broader ecological environment. Several strategies have been developed to address AMR, including the Global Action Plan (GAP), National Action Plans (NAPs), AMS programs, and implementation of the AWaRe classification of antimicrobials. These strategies also involve strengthening surveillance of antimicrobial consumption and resistance, encouraging the development of new antimicrobials, and enhancing regulations around antimicrobial prescribing, dispensing, and usage. Additional measures include promoting global partnerships, combating substandard and falsified antimicrobials, advocating for vaccinations, sanitation, hygiene and biosecurity, as well as exploring alternatives to antimicrobials. However, the implementation of these strategies faces various challenges. These challenges include low awareness and knowledge of AMR, a shortage of human resources and capacity building for AMR and AMS, in adequate funding for AMR and AMS initiatives, limited laboratory capacities for surveillance, behavioural change issues, and ineffective leadership and multidisciplinary teams. Conclusion: In conclusion, this study established that AMR is prevalent among humans, animals, and the environment. S 展开更多

Background: Supermarkets are a place visited by individuals with different health conditions daily where microbiological contaminants through touch onto fomites such as trolleys and baskets can be passed on to other people hence potentially spreading infectious diseases. This study aimed to investigate the presence of Gram-negative and Gram-positive bacteria on handheld shopping trolleys and baskets and their antimicrobial susceptibility status against commonly used antibiotics in Zambia. Methods: A cross-sectional study was conducted. Trolleys and basket handles were swabbed and standard microbiological methods were used to identify the bacteria and disc diffusion to determine their antimicrobial susceptibility status. Data was collected from December 2021 to April 2022. Data was analysed using IBM Statistical Package for Social Sciences (SPSS) Version 22. Results: Twenty-eight percent of the 200 total samples were found to be culture-positive and predominant isolates were Staphylococcus aureus (17.3%), Pseudomonas species (4.5%), Escherichia coli (2%), Corynebacterium species (2%), Staphylococcus species (1.5%) and Enterobacter aerogenes (0.5%). Staphylococcus aureus showed the most resistance to azithromycin (17%) followed by ciprofloxacin (2.8%), nitrofurantoin (2.8%) and chloramphenicol (2.8%). Escherichia coli showed 100% resistance to amoxicillin, cloxacillin and ampicillin, 75% resistance to ciprofloxacin and the least resistance to azithromycin (25%) while it was susceptible to nitrofurantoin. Staphylococcus species, Corynebacterium species, Enterobacter aerogenes and Pseudomonas species showed no resistance to any antibiotics. Conclusion: The study showed the presence of microorganisms with considerable antimicrobial resistance to antibiotics in Zambia on trolley and basket handles indicating the need for more initiatives to address proper hygiene in public environmental sites for better infection prevention and control. 展开更多

Introduction: The inappropriate antimicrobial usage (AMU) in chicken production has led to an increase in the prevalence of antimicrobial resistance (AMR). In Zambia, there is little information documented regarding the knowledge, attitude, and practices of poultry farmers on AMU and AMR. Therefore, this study assessed the knowledge, attitude and practices regarding AMU and AMR among poultry farmers in Kitwe, Zambia. Methods: This was a cross-sectional study conducted among 106 poultry farmers from November to December 2021 using a structured questionnaire. Data analysis was done using IBM Statistical Package for Social Sciences (SPSS) version 26. Results: Overall, of the 106 participants, 90.6% knew what antimicrobials were, but only 29.2% were aware of AMR. The study showed that 46.2% of the participants had low knowledge, 71.7% had negative attitudes, and 61.3% had poor practices regarding AMR. The prevalence of antibiotic use in poultry production was 83%. The most used antimicrobials were tetracycline (84%) and gentamicin (35.2%). The commonly reported reason for the use of antimicrobials was for the treatment (93.2%) and prevention (89.8%) of diseases. Further, 76.9% of the administered antimicrobials were usually done without veterinarian consultation or prescription. Conclusion: The study shows that there was high AMU in poultry farms in Kitwe. However, there was low knowledge, negative attitude, and poor practices towards AMU and AMR. Therefore, there is a need for educational and sensitisation programmes regarding AMU and AMR among poultry farmers in Kitwe, Zambia. Alongside this, antimicrobial stewardship and surveillance systems should be strengthened in the livestock production sector. This will ensure food safety and public health. 展开更多

Introduction: A caesarean section (CS) is one of the most frequently performed obstetric surgeries in the world and its use has increased dramatically in recent years. The number of caesarean section cases worldwide has been increasing each year, and the World Health Organization (WHO) reported an excess of 10% - 15% of CS procedures for all births. However, some women experience surgical site infections (SSIs) after undergoing CS delivery. This study investigated the prescribing patterns of antibiotics in CS deliveries and the prevalence of SSIs at two tertiary hospitals in Lusaka, Zambia. Materials and Methods: A retrospective cross-sectional study was conducted from January 2020 to December 2020 at the Women and Newborn University Teaching Hospital (UTH) and the Levy Mwanawasa University Teaching Hospital, in Lusaka, Zambia. Results: Of a total of 838 women who delivered via CS, more than half were aged between 21 and 25 years (n = 461, 55.0%), 56.3% were from low-cost residential areas, and 57% had emergency CS delivery. The prevalence of SSIs was 6.0%, with the level of education (OR 0.377, 95% CI 0.150 - 0.946), type of caesarean section (OR 6.253, 95% CI 2.833 - 13.803), and oral antibiotics post-caesarean (OR 0.218, 95% CI 0.049 - 0.963). The duration of IV antibiotic treatment significantly predicted SSI (p Conclusion: This study found that the third-generation cephalosporin (cefotaxime) and triple combination therapy (benzylpenicillin, gentamicin, and metronidazole) were the most frequently prescribed antibiotics before and after CS. The level of education, type of CS, oral antibiotics post-CS, facility, and duration of administering IV antibiotics were all predictors of SSIs. 展开更多

Introduction: Indiscriminate prescribing and using of antibiotics have led to the development of antimicrobial resistance (AMR). To reduce this problem, the World Health Organization (WHO) developed the “Access”, “Watch”, and “Reserve” (AWaRe) classification of antibiotics that promotes antimicrobial stewardship (AMS). In Zambia, there are gaps in practice regarding prescribing of antibiotics based on the AWaRe protocol. This study assessed antibiotic prescribing patterns in adult in-patients in selected primary healthcare hospitals in Lusaka, Zambia. Materials and Methods: This retrospective cross-sectional study was conducted using 388 patient medical files from September 2021 to November 2021, five primary healthcare hospitals namely;Chawama, Matero, Chilenje, Kanyama, and Chipata. Data analysis was performed using the Statistical Package for Social Sciences version 23. Results: Of the selected medical files, 52.3% (n = 203) were for male patients. Overall, the prevalence of antibiotic use was 82.5% (n = 320) which was higher than the WHO recommendation of a less than 30% threshold. The most prescribed antibiotic was ceftriaxone (20.3%), a Watch group antibiotic, followed by metronidazole (17.8%) and sulfamethoxazole/trimethoprim (16.3%), both belonging to the Access group. Furthermore, of the total antibiotics prescribed, 41.9% were prescribed without adhering to the standard treatment guidelines. Conclusion: This study found a high prescription of antibiotics (82.5%) that can be linked to non-adherence to the standard treatment guidelines in primary healthcare hospitals. The most prescribed antibiotic was ceftriaxone which belongs to the Watch group, raising a lot of concerns. There is a need for rational prescribing of antibiotics and implementation of AMS programs in healthcare facilities in Zambia, and this may promote surveillance of irrational prescribing and help reduce AMR in the future. 展开更多

The coronavirus disease 2019 (COVID-19) has caused many global challenges, especially in resource-constrained countries. Africa, a continent with a large number of low-and middle-income countries (LMICs), shares this burden disproportionately compared to developed countries. Here we review some of the major challenges African countries face in the fight against COVID-19 and propose some mitigation measures. Studies have reported low adherence to COVID-19 prevention measures in most African countries. Additionally, there has been a shortage of healthcare workers, inadequate surveillance and diagnostic tools, unavailability of drugs in healthcare facilities, increased wrong beliefs, myths, misinformation and misconceptions about COVID-19 and vaccinations, and an already existing burden of infectious and non-infectious diseases across the African continent. Despite being very challenging to implement across African countries, telehealth is a critical solution to offer healthcare services during disease outbreaks. Many African countries have faced challenges in the fight against COVID-19. The training of healthcare workers (HCWs) must be strengthened to help address the shortage. In addition, African countries should strive to invest in research and capacity-building to be self-reliant regarding diagnostic tests. Thus, there is an urgent need to address the challenges faced by African countries in this fight, which may even include increased collaborations with other countries. 展开更多

Background: The coronavirus disease 2019 (COVID-19) is a public health problem that has caused harm to the mental health of healthcare workers. In Africa, the COVID-19 pandemic has led healthcare workers to experience mental health disorders such as anxiety, depression, stress, insomnia and burnout. This study aimed to review published studies on the effect of COVID-19 on the mental health of healthcare workers, associated factors and coping strategies that have been employed in Africa. Methods: This was a systematic review that was conducted through searching databases including;PubMed/Medline and Google Scholar. The study included published literature from January 2020 to May 2022 that met the inclusion criteria. The selection of articles was conducted following the 2020 PRISMA guidelines. Results: A total of 39 articles were retrieved, of which only 18 met the inclusion criteria and were used in this study. Our review revealed that healthcare workers experienced mental health disorders such as anxiety, depression, insomnia, stress and burnout that were associated with the COVID-19 pandemic. Coping strategies such as religious practices, support from family members and colleagues and avoiding listening to social media about COVID-19 were used to minimize mental health problems. Conclusion: The COVID-19 pandemic has caused increased mental health disorders among healthcare workers in Africa. Identification of factors associated with mental health problems is cardinal in developing coping mechanisms against the psychological impact of COVID-19. Therefore, there is a need for governments to develop and implement strategies for protecting the mental health of healthcare workers during crises such as the COVID-19 pandemic. 展开更多
