Factors associated with the unsuccessful TB treatment outcomes in the northern regions of Namibia: a mixed methods study.

BACKGROUND: Tuberculosis (TB) is among the leading causes of death globally. The disease has a huge burden in Namibia, with a case notification rate of at least 442 per 100,000. To date, Namibia is among the countries with the highest global TB burden, despite all efforts to reduce it. This study aimed to determine the factors associated with the unsuccessful treatment outcomes of the Directly Observed Therapy Short course (DOTS) programme in the Kunene and Oshana regions. METHODS: The study utilised a mixed-methods explanatory-sequential design to collect data from all TB patient records and healthcare workers who work directly with the DOTS strategy for TB patients. The relationship between independent and dependent variables was analysed using multiple logistic regression analysis, while interviews were analysed using inductive thematic analysis. RESULTS: The overall treatment success rates of the Kunene and Oshana regions throughout the review period were 50.6% and 49.4%, respectively. The logistic regression analyses showed that in the Kunene region, the type of DOT used (Community-based DOTS) (aOR = 0.356, 95% CI: 0.835-2.768, p = 0.006) was statistically significant with the unsuccessful treatment outcomes. While in the Oshana region, age groups 21-30 years old (aOR = 1.643, 95% CI = 1.005-2.686, p = 0.048), 31-40 years old (aOR = 1.725, 95% CI = 11.026-2.9, p = 0.040), 41-50 years old (aOR = 2.003, 95% CI = 1.155-3.476, p = 0.013) and 51-60 years old (aOR = 2.106, 95% CI = 1.228-3.612, p = 0.007) had statistically significant associations with the poor TB-TO. Inductive thematic analysis revealed that patients in the Kunene region were challenging to reach owing to their nomadic lifestyle and the vastness of the area, adversely affecting their ability to observe TB therapy directly. In the Oshana region, it was found that stigma and poor TB awareness among adult patients, as well as mixing anti-TB medication with alcohol and tobacco products among adult patients, was a prevalent issue affecting TB therapy. CONCLUSION: The study recommends that regional health directorates embark on rigorous community health education about TB treatment and risk factors and establish a robust patient observation and monitoring system to enhance inclusive access to all health services and ensure treatment adherence.

Barriers to the provision of smoking cessation intervention/services: A mixed-methods study among health care workers in Zambezi region, Namibia.

Background: Healthcare workers (HCWs) can play a significant role in tobacco prevention by delivering smoking cessation (SC) interventions to patients who smoke. Objective: To identify and explore the perceived barriers which prevent healthcare workers from delivering SC counselling to patients in Zambezi region, Namibia. Methods: A regional-based, concurrent mixed-methods study was conducted between March and October 2020 among HCWs of the 8 constituencies of Zambezi region, Namibia. In the study, 129 respondents, who had been residents of the selected constituencies for over 5 years and aged between 17 to 60 years, participated. Results: 129 respondents participated in the study. Majority of respondents were females (62.9% and 68.1%) compared to (37.1% and 31.9%) males. The mean age of respondents was 35.91 (SD=9.3) and 36.61 (SD=8.7) respectively and their ages ranged between 18 and 59 years. Key barriers were identified: (i) HCWsbased barriers included lack of time to provide SC, inadequate training and insufficient knowledge on SC interventions; (ii) system- based barriers identified lack of SC guidelines and educational materials for patients, and specialists to refer patients; and (iii) patient/client-based barriers included lack of patient interest in SC information, patients not adhering to advise given on SC. Conclusions: This study showed that SC delivery in Zambezi region is inadequate. Barriers were identified regarding the delivery of SC intervention for the first time. Targeted SC interventions are required to combat these identified specific barriers. There is a crucial need to improve HCWs skills and knowledge in providing SC intervention.

Using mobile phone data to reveal risk flow networks underlying the HIV epidemic in Namibia.

Twenty-six million people are living with HIV in sub-Saharan Africa; epidemics are widely dispersed, due to high levels of mobility. However, global elimination strategies do not consider mobility. We use Call Detail Records from 9 billion calls/texts to model mobility in Namibia; we quantify the epidemic-level impact by using a mathematical framework based on spatial networks. We find complex networks of risk flows dispersed risk countrywide: increasing the risk of acquiring HIV in some areas, decreasing it in others. Overall, 40% of risk was mobility-driven. Networks contained multiple risk hubs. All constituencies (administrative units) imported and exported risk, to varying degrees. A few exported very high levels of risk: their residents infected many residents of other constituencies. Notably, prevalence in the constituency exporting the most risk was below average. Large-scale networks of mobility-driven risk flows underlie generalized HIV epidemics in sub-Saharan Africa. In order to eliminate HIV, it is likely to become increasingly important to implement innovative control strategies that focus on disrupting risk flows.

The role of Namibia Field Epidemiology and Laboratory Training Programme in strengthening the public health workforce in Namibia, 2012-2019.

Namibia faces a critical shortage of skilled public health workers to perform emergency response operations, preparedness activities and real-time surveillance. The Namibia Field Epidemiology and Laboratory Training Programme (NamFELTP) increases the number of skilled public health professionals and strengthens the public health system in Namibia. We describe the NamFELTP during its first 7 years, assess its impact on the public health workforce and provide recommendations to further strengthen the workforce. We reviewed disease outbreak investigations and response reports, field projects and epidemiological investigations conducted during 2012-2019. The data were analysed using descriptive methods such as frequencies and rates. Maps representing the geographical distribution of NamFELTP workforce were produced using QGIS software V.3.2. There were no formally trained field epidemiologists working in Namibia before the NamFELTP. In its 7 years of operation, the programme graduated 189 field epidemiologists, of which 28 have completed the Advanced FELTP. The graduates increased epidemiological capacity for surveillance and response in Namibia at the national and provincial levels, and enhanced epidemiologist-led outbreak responses on 35 occasions, including responses to outbreaks of human and zoonotic diseases. Trainees analysed data from 51 surveillance systems and completed 31 epidemiological studies. The NamFELTP improved outcomes in the Namibia's public health systems; including functional and robust public health surveillance systems that timely and effectively respond to public health emergencies. However, the current epidemiological capacity is insufficient and there is a need to continue training and mentorship to fill key leadership and strategic roles in the public health system.

Epidemiology and factors associated with diarrhoea among children under five years of age in the Engela District in the Ohangwena Region, Namibia.

BACKGROUND: Diarrhoea remains a public health problem and an important cause of morbidity and mortality amongst children, mainly in low- and middle-income countries. In Namibia, the national prevalence of diarrhoea was 17%; it was responsible for 5% of all deaths in children under 5 years old and is the second leading cause of death. AIM: The purpose of this study was to assess the epidemiology and factors associated with acute diarrhoea amongst children less than 5 years of age in Engela district in the Ohangwena region, Namibia. SETTING: The study was conducted in Ohangwena Region in Namibia which extends east to west along the borders of the southern part of Angola. METHODS: A cross-sectional study was conducted. A structured questionnaire was administered through face-to-face interviews. Descriptive statistics were used to describe the socio-demographic and epidemiological data of diarrhoea and logistic regression analysis was used to determine the factors associated with the prevalence of diarrhoea. RESULTS: The study found a prevalence of 23.8% for diarrhoea in the 2 weeks period preceding the survey amongst children aged under 5 years. The prevalence of diarrhoea was statistically significantly associated with children (p 0.05). The strongest predictor of the prevalence of diarrhoea was the residential area 'informal settlement', with an odds ratio of 36.42. This implies that children living in the informal settlement are 36.42 times at risk of contracting diarrhoea as compared to those living in other residential areas. CONCLUSION: epidemiology; factors; diarrhoea; under-5 years children; Engela district; Ohangwena region; Namibia.

What works and what does not work in response to COVID-19 prevention and control in Africa.

Since the emergence of the COVID-19 pandemic in December 2019 in Wuhan, China, there have been nearly 6,663,304 confirmed cases of COVID-19, including 392,802 deaths, worldwide as of 10:00 CEST 06 June 2020. In Africa, 152,442 COVID-19 cases and 4334 deaths have been reported as of 02 June 2020. The five countries with the highest commutative number of cases in Africa are South Africa, Egypt, Nigeria, Algeria, and Ghana. Africa, and the rest of world, has had to swiftly undertake the necessary measures to protect the continent from irreversible effects of the COVID-19 pandemic that is claiming lives and destroying livelihoods. The lower number of COVID-19 cases in most African countries is attributed to inadequate health systems, low-to-absent testing capacity, poor reporting systems, and insufficient numbers of medical staff. The COVID-19 pandemic poses a great threat to most African countries, from cities to rural areas, and has created a strong demand on already scarce resources. Intense mobilization of additional resources is required to implement established emergency contingency measures. Measures to prevent the spread of COVID-19 include closure of borders and restricting movement of people within a country; this has resulted in the tourism sector being adversely affected by the loss of income. Cooperative prevention and control measures are one of the promising solutions to deplete the spread of COVID-19 on the continent.
