The urban areas of many low-income countries must balance a rising demand for pit latrines for household sanitation provision against limitations in space, resulting in a need for pit latrine emptying services. This study was undertaken in the peri-urban neighborhood of Area 1B in the city of Mzuzu, Malawi, to examine the characteristics of household pit latrines for designing and selecting pit latrine emptying tools. We used 150 structured household surveys and field observations. From this, a subset was selected and 30 manual cone penetrometer tests were conducted at full latrines. Chemical oxygen demand analysis was also performed for 14 pit latrines. The results indicated that in addition to serving as a disposal for fecal matter, 90% of households also used pit latrines for domestic waste. Only 10% of the studied pit latrines were lined. The filling rate in the study area is calculated to be about three years, and no respondents reported previous emptying. It is suggested pit latrine emptying technology development focuses on a maximum tool diameter of 10 cm to fit through the keyhole (squat hole) and height of 146 cm to fit inside the superstructure, as well as supporting unlined pits and the ability to pump trash.

Introduction Recent debates surrounding the lagging covid-19 vaccination campaigns in low-income countries center around vaccine supply and financing. Yet, relatively little is known about attitudes towards covid-19 vaccines in these countries and in Africa in particular. In this paper, we provide cross-country comparable estimates of the willingness to accept a covid-19 vaccine in six Sub-Saharan African countries. Methods We use data from six national high-frequency phone surveys from countries representing 38% of the Sub-Saharan African population (Burkina Faso, Ethiopia, Malawi, Mali, Nigeria, and Uganda). Samples are drawn from large, nationally representative sampling frames providing a rich set of demographic and socio-economic characteristics by which we disaggregate our analysis. Using a set of re-calibrated survey weights, our analysis adjusts for the selection biases common in remote surveys. Results Acceptance rates in the six Sub-Saharan African countries studied are generally high, with at least four in five people willing to be vaccinated in all but one country. Vaccine acceptance ranges from nearly universal in Ethiopia (97.9%, 97.2% to 98.6%) to below what would likely be required for herd immunity in Mali (64.5%, 61.3% to 67.8%). We find little evidence for systematic differences in vaccine hesitancy by sex or age but some clusters of hesitancy in urban areas, among the better educated, and in richer households. Safety concerns about the vaccine in general and its side effects emerge as the primary reservations toward a covid-19 vaccine across countries. Conclusions Our findings suggest that limited supply, not inadequate demand, likely presents the key bottleneck to reaching high covid-19 vaccine coverage in Sub-Saharan Africa. To turn intent into effective demand, targeted communication campaigns bolstering confidence in the safety of approved vaccines and reducing concerns about side effects will be crucial to safeguard the swift progression of vaccine rollout in one of the world's poorest regions.

Abstract Background The onset of the covid19 pandemic has sparked heated debate among scholars on the relevance of lockdowns. There are those in favor of the lockdown and others who are critical of it. However, despite the increased interest in understanding the relevance of lockdowns, there still has not been much focus on its relevance in low income countries like Zambia. Thus with the help of the SRT, we set out to explore and document the local characterization of the lockdown by residents of Lusaka, Zambia.Methods A qualitative study in the form of interviews was conducted in Lusaka, Zambia involving a sample of 68 participants. Due to the lockdown measures that were in place during the study, the interviews were conducted via phone calls and the data collected were later analyzed by use of thematic analysis technique.Results The lockdown was on one hand lauded for slowing down the incidence rates, preventing fatalities, and for protecting the healthcare system from collapse. On the other hand, it was criticized for exacerbating poverty levels, unemployment rates, increasing the rate of mental health problems, aiding gender based violence, and intensifying political repression and corruption. The results speak to the complexity in the characterization of the lockdown as a response to covid19 in Zambia. This observation demonstrates the folly of viewing, applying and characterizing the covid19 lockdown as a ‘one-size-fits-all’ approach in Zambia.Conclusion Thus rather than definitely establishing the lockdown as an incontestable good, as it is depicted by some scholars or as useless by its critics, our findings instead demonstrate the diversity and complexity in how it is locally viewed by Zambians. The study provides grounds for caution on simplistic and binary characterization of lockdowns. It indicates the need for careful dialog between the designers of lockdowns and citizens in order to tailor such interventions to local realities in context-specific ways. It also shows that though the development of such interventions, all the various and complex elements it embodies must be taken into account in order to realize optimum outcomes.

IntroductionPrevalence of cardiovascular disease risk factors (CVDRFs) is increasing, especially in low-income countries. In Sierra Leone, there is limited empirical data on the prevalence of CVDRFs, and there are no previous studies on the access to care for these conditions.MethodsThis study in rural and urban Sierra Leone collected demographic, anthropometric measurements and clinical data from randomly sampled individuals over 40 years old using a household survey. We describe the prevalence of the following risk factors: diabetes, hypertension, dyslipidaemia, overweight or obesity, smoking and having at least one of these risk factors. Cascades of care were constructed for diabetes and hypertension using % of the population with the disease who had previously been tested (‘screened’), knew of their condition (‘diagnosed’), were on treatment (‘treated’) or were controlled to target (‘controlled’). Multivariable regression was used to test associations between prevalence of CVDRFs and progress through the cascade for hypertension with demographic and socioeconomic variables. In those with recognised disease who did not seek care, reasons for not accessing care were recorded.ResultsOf 2071 people, 49.6% (95% CI 49.3% to 50.0%) of the population had hypertension, 3.5% (3.4% to 3.6%) had diabetes, 6.7% (6.5% to 7.0%) had dyslipidaemia, 25.6% (25.4% to 25.9%) smoked and 26.5% (26.3% to 26.8%) were overweight/obese; a total of 77.1% (76.6% to 77.5%) had at least one CVDRF. People in urban areas were more likely to have diabetes and be overweight than those living in rural areas. Moreover, being female, more educated or wealthier increased the risk of having all CVDRFs except for smoking. There is a substantial loss of patients at each step of the care cascade for both diabetes and hypertension, with less than 10% of the total population with the conditions being screened, diagnosed, treated and controlled. The most common reasons for not seeking care were lack of knowledge and cost.ConclusionsIn Sierra Leone, CVDRFs are prevalent and access to care is low. Health system strengthening with a focus on increased access to quality care for CVDRFs is urgently needed.

Subject Cancer burden in Africa. Significance Cancer is a growing public health threat in low-income countries, including African states. With the increase in urbanisation, population growth and improving mortality rates, the World Health Organisation (WHO) estimates that by 2020, 16 million new cases of cancer will be diagnosed each year, with 70% of those in low-income countries. However, the rise in cancer rates has not been met with changes to aid funding. Global health priorities continue to emphasise infectious diseases, and African countries remain ill-equipped to prevent, diagnose or treat cancer. Impacts Rising consumption of processed foods in urban areas will contribute to an overall rise in non-communicable diseases. African countries are some of the fastest growing markets for tobacco companies as health awareness rises in traditional markets. Global brewers will enjoy significant market expansion in Africa, contributing to increased alcohol consumption. Despite the economic benefits, delayed childbearing and lower fertility in women is set to increase the incidence of breast cancer.

Introduction: Globally, poor sanitation is the cause of childhood diseases. Annually, more than 19,500 people die from diarrhea of which 17,100 are children. Diarrhea, which accounts for 16% of deaths among the children below 5 years, is highly linked to open defecation (OD). Poor excreta disposal remains a major challenge to improved sanitation and hygiene in many communities of Kenya and therefore they continue to practice open defecation. Construction and utilization of a latrine at home is a protective factor for communicable diseases.  About 52% of the population practice proper utilization of latrine in low-income countries. Improper utilization of latrines leads to the contamination of the water sources. Availability of a pit latrine does not guarantee utilization because other factors like functionality and distance influence its use. Furthermore, the availability and use of the latrine depends on maintenance practices of the latrines and cleanliness as well as the quality of housing and household compound. Aims: To analyze the physical and social demographic factors influencing the utilization of pit latrines in Tigania East Sub-County, Meru County, Kenya. Study Design:  The study was a descriptive cross-sectional survey. Place and Duration of Study: The study was carried out in Tigania East Sub-County, Meru County, Kenya shown in Fig. 3. Household survey was carried out between June 2018 and December 2019. Methodology: This was a descriptive cross-sectional survey involving 369 respondents selected by systematic random sampling from different households across the sub-county was utilized. Data collection was done using a structured questionnaire administered in English and a spot observation checklist. All data generated was entered, validated and analyzed using SPSS using SPSS Software Version 23.  Descriptive analysis was done during the calculation of measures of central tendency and proportions. Regression analysis was used in the determination of any association between the socio-demographic factors and the utilization of latrines. Results: Ownership, location and functionality of the pit latrine were positively associated with utilization (OR=2.127, OR=1.53, OR=4.36, P=.00). Households that owned pit latrines were 2 times likely to utilize the pit latrines than those without a pit latrine. Moreover, household size, gender, and employment were positively related to utilization (R=0.502, P=.00). High construction costs challenges were 7 times linked to open defecation practices. Households with less than 6 members were 2.35 times more likely to utilize the pit latrine compared to those with 7-12 members (OR=2.35, X²=13.573, P=.00). Conclusion: Interventions should target households with more than 7 members. A call for partnerships between government and donors to improve household income, water sources, and sanitation practices in Tigania East Sub-County is necessary. A call for funding projects related to pour-flush pit latrines and wet technologies to enhance utilization.

Today, the world’s fastest-growing cities lie in low-income countries, unlike the historical norm. Also, unlike the “killer cities” of history, cities in low-income countries grow not just through in-migration but also through their own natural increase. First, we use novel historical data to document that many poor countries urbanized at the same time as the postwar urban mortality transition. Second, we develop a framework incorporating location choice with heterogeneity in demographics and congestion costs across locations to account for this. In the framework, people prefer to live in low-mortality locations, and the aggregate rate of population growth and the locational choice of individuals interact. Third, we calibrate this to data from a sample of poor countries and find that informal urban areas (e.g., slums) can absorb additional population more easily than other locations. We show that between 1950 and 2005 the urban mortality transition could have doubled the urbanization rate as well as the size of informal urban areas in this sample. Of these effects, one-third could be attributed to the amenity effect of lower urban mortality rates, while the remainder is due to higher population growth disproportionately pushing people into informal urban areas. Fourth, simulations suggest that family planning programs, as well as industrialization or urban infrastructure and institutions may be effective in slowing poor-country urbanization.

Abstract : Malaria, a protozoan disease led to numerous deaths and several new million cases raised due to the development of resistance as per the WHO malaria report 2019. This can be overcome by the development of an effective targeted plant-based delivery system through phytosomes that are effective in permeation and bioavailability to treat infected RBCs (parasitic cells). This review article explained the development of targeted Nanophytosomes to overcome resistance, to improve efficacy. This review paper also emphasized various quality-driven developmental approaches in developing an antimalarial product at a reasonable cost. By implementing molecular modeling techniques in development, a significant phytoconstituent with the capability of acting at the target (receptor or enzymes) of the parasite and the one with the capability to overcome drug resistance against resistant strains of parasites can be identified. Absorption Distribution Metabolism Excretion and Toxicity (ADMET) studies information provide a route to the design and formulation of a potent antimalarial agent. Efficient targeted Nanophytosomal formulations can be formulated by functionalizing or conjugating with suitable targets to direct the phytoconstituent to the infected RBCs thereby achieving complete parasitic eradication. Artificial Neural Network technology (ANN), Quality by Design (QbD), molecular dynamics, and simulation studies implementation improves quality and reduces the cost of the product, as these malarial products are much utilized in low-income countries. Hence it can be concluded that targeted developmental quality-driven approaches implementation is essential for effective malarial treatment.
