Farmers’ Perception and Farming Practices on the Effect of Early and Late Leaf Spots on Groundnut Production in Northern Ghana
Groundnut (Arachis hypogaea L.) is an important crop both in subsistence and commercial agriculture in Ghana. Early leaf spot (Cercospora arachidicola) and late leaf spot (Phaeoisariopsis personata) are major limiting factors to groundnut productivity in Ghana. The objective of the study was to appraise farmers’ perception of the disease and effect of the cropping system on the incidence and severity of the disease. A disease-based questionnaire was administered to 100 farmers in their local language spread across 10 villages and towns selected from Tamale, Tolon-Kunbungu and Savelugu-Nanton Districts, all in the Northern Region of Ghana. The responses of the farmers showed that Cercospora leaf spot (ELS and LLS) was perceived by the farmers as one of the major constraints to groundnut production in the area to which farmers have no solution. The severity of the disease was dependent on the cropping system adopted by the farmers. The variety Chinese turned out to be the most important commercial cultivar grown by farmers but it is susceptible to both diseases.

A typical Kawasaki syndrome in COVID-19 infection: a case report of a multisystem inflammatory syndrome in a child (MIS-C)
The emergence of COVID-19 by a novel severe acute respiratory syndrome coronavirus (SARS-CoV-2) in 2019 has seen evolving data reporting infrequent infection in children and mostly mild disease for children who contract the infection. A severe form of COVID-19 in children recently reported in Europe and North America describes a multisystem inflammation syndrome in children (MIS-C), presenting as toxic-shock-like and Kawasaki-like syndromes. Data on MIS-C in Africa is being documented with recent reports from South Africa and Nigeria in black children, but information on MIS-C in Ghana is yet to be characterized. We report the first case of multisystem inflammatory syndrome in a child who tested PCR positive to SARS-CoV2 in a tertiary hospital in Ghana. The case describes a 10-year-old boy who reported Kawasaki-like syndrome without shock but with moderate respiratory distress requiring supportive acute care without the need for intensive care
PRELIMINARY RESULTS ON THE DEVELOPM ENT OF INNOVATIVE SITE-SPECIFIC INTEGRATED ANIMAL HEALTH PACKAGES FOR THE RURAL POOR
A Spatio-temporal Model of African Animal Trypanosomosis Risk
[b]Background[/b]African animal trypanosomosis (AAT) is a major constraint to sustainable development of cattle farming in sub-Saharan Africa. The habitat of the tsetse fly vector is increasingly fragmented owing to demographic pressure and shifts in climate, which leads to heterogeneous risk of cyclical transmission both in space and time. In Burkina Faso and Ghana, the most important vectors are riverine species, namely Glossina palpalis gambiensis and G. tachinoides, which are more resilient to human-induced changes than the savannah and forest species. Although many authors studied the distribution of AAT risk both in space and time, spatio-temporal models allowing predictions of it are lacking.[b]Methodology/Principal Findings[/b]We used datasets generated by various projects, including two baseline surveys conducted in Burkina Faso and Ghana within PATTEC (Pan African Tsetse and Trypanosomosis Eradication Campaign) national initiatives. We computed the entomological inoculation rate (EIR) or tsetse challenge using a range of environmental data. The tsetse apparent density and their infection rate were separately estimated and subsequently combined to derive the EIR using a "one layer-one model" approach. The estimated EIR was then projected into suitable habitat. This risk index was finally validated against data on bovine trypanosomosis. It allowed a good prediction of the parasitological status (r(2) = 67%), showed a positive correlation but less predictive power with serological status (r(2) = 22%) aggregated at the village level but was not related to the illness status (r(2) = 2%).[b]Conclusions/Significance[/b]The presented spatio-temporal model provides a fine-scale picture of the dynamics of AAT risk in sub-humid areas of West Africa. The estimated EIR was high in the proximity of rivers during the dry season and more widespread during the rainy season. The present analysis is a first step in a broader framework for an efficient risk management of climate-sensitive vector-borne diseases
Community perceptions of malaria and malaria treatment behaviour in a rural district of Ghana: implications for artemisinin combination therapy
<p>Abstract</p> <p>Background</p> <p>Artesunate-amodiaquine (AS-AQ) was introduced in Ghana as the first line drug for treatment of uncomplicated malaria in 2004. We report the perceptions of malaria and malaria treatment behaviour, the community awareness of and perceptions about AS-AQ two years after the introduction of this ACT treatment for malaria.</p> <p>Methods</p> <p>Two surveys were conducted; a cross-sectional survey of 729 randomly selected household heads (urban-362, rural-367) and 282 women with children < 5 years (urban-121, rural-161) was conducted in 2006. A district wide survey was conducted in 2007 to assess awareness of AS-AQ. These were complemented with twenty-eight focus group discussions (FGDs) and 16 key informant interviews (KII) among community members and major stakeholders in the health care delivery services. All nine (9) health facilities and five (5) purposively selected drug stores were audited in order to identify commonly used anti-malarials in the study area at the time of the survey.</p> <p>Results</p> <p>Majority of respondents ( > 75%) in the sampled survey mentioned mosquito bites as the cause of malaria. Other causes mentioned include environmental factors (e.g. dirty surroundings) and standing in the sun. Close to 60% of the household heads and 40% of the care-givers interviewed did not know about AS-AQ. The community respondents who knew about and had ever taken AS-AQ perceived it to be a good drug; although they mentioned they had experienced some side effects including headaches and body weakness. Co-blistered AS-AQ was available in all the government health facilities in the study area. Different formulations of ACTs were however found in urban chemical shops but not in rural chemical stores where monotherapy antimalarials were predominant.</p> <p>Conclusion</p> <p>The knowledge of fever as a symptom of malaria is high among the study population. The awareness of AS-AQ therapy and its side-effect was low in the study area. Community education and sensitization, targeting all categories of the population, has to be intensified to ensure an efficient implementation process.</p
Open defecation and attainment of Sustainable Development Goal Six: evidence from Kintampo Surveillance System, Ghana.
OBJECTIVE: This study examined whether the open-defecation (OD) free target is achievable by 2030. DESIGN: Longitudinal study. SETTING: Seven sub-Districts of Kintampo North Municipal, and five sub-Districts of Kintampo South District. DATA SOURCE: Kintampo health and demographic surveillance system PARTICIPANTS: Data was collected from household heads or their representatives over a 12-year period from 2005 to 2016. MAIN OUTCOME: Open-defecation and attainment of OD free by 2030. RESULTS: In an exploratory analysis, the correlation between the total number of households, year, and total number of OD households was obtained. The average percentage yearly increase or decrease in OD was computed and used to project the percentage of OD for the years 2020, 2025 and 2030. In addition, geo-spatial technology was used to visualize variability in OD across the twelve sub-Districts. The results showed that the OD free target is not achievable in 2030 or even if the current trend continues. In 2016, 44.2 per cent of the 31,571 households defecated openly. In six out of the 12 sub-Districts, more than half of the households openly defecated. Four out of these six sub-Districts were in the Kintampo North Municipality.Conclusion: The 2030 OD free target is not achievable in the Kintampo districts of Ghana if the current trend continues
The sequential aerosol technique : a major component in an Iitegrated strategy of intervention against riverine Tsetse in Ghana
An integrated strategy of intervention against tsetse flies was implemented in the Upper West Region of
Ghana (9.62u–11.00u N, 1.40u–2.76u W), covering an area of <18,000 km2 within the framework of the Pan-African Tsetse
and Trypanosomosis Eradication Campaign. Two species were targeted: Glossina tachinoides and Glossina palpalis
gambiensis.
METHODOLOGY/PRINCIPAL FINDINGS: The objectives were to test the potentiality of the sequential aerosol technique (SAT) to
eliminate riverine tsetse species in a challenging subsection (dense tree canopy and high tsetse densities) of the total
sprayed area (6,745 km2) and the subsequent efficacy of an integrated strategy including ground spraying (<100 km2),
insecticide treated targets (20,000) and insecticide treated cattle (45,000) in sustaining the results of tsetse suppression in
the whole intervention area. The aerial application of low-dosage deltamethrin aerosols (0.33–0.35 g a.i/ha) was conducted
along the three main rivers using five custom designed fixed-wings Turbo thrush aircraft. The impact of SAT on tsetse
densities was monitored using 30 biconical traps deployed from two weeks before until two weeks after the operations.
Results of the SAT monitoring indicated an overall reduction rate of 98% (from a pre-intervention mean apparent density
per trap per day (ADT) of 16.7 to 0.3 at the end of the fourth and last cycle). One year after the SAT operations, a second
survey using 200 biconical traps set in 20 sites during 3 weeks was conducted throughout the intervention area to measure
the impact of the integrated control strategy. Both target species were still detected, albeit at very low densities (ADT of
0.27 inside sprayed blocks and 0.10 outside sprayed blocks).
CONCLUSIONS/SIGNIFICANCE: The SAT operations failed to achieve elimination in the monitored section, but the subsequent
integrated strategy maintained high levels of suppression throughout the intervention area, which will contribute to
improving animal health, increasing animal production and fostering food security.The work was funded by the Pan-African Tsetse and Trypanosomosis Eradication Campaign/Ghana and the International Fund for Agricultural
Development (IFAD) (project GCP/RAF/442/IFA).http://www.plosntds.org /home.actionam2013ab201

Family Planning Awareness, Perceptions and Practice among Community Members in the Kintampo Districts of Ghana
Family planning is known to prevent maternal deaths, but some social norms, limited supplies and inconsistent use makes this difficult to achieve in most low- and middle-income countries. In spite of the high fertility levels in most sub-Saharan African countries and the potential economic benefits of family planning, its patronage remains very low in the sub-region. This study was with the objective of identifying the levels of awareness, utilization, access to and perceptions about family planning and contraception. A cross-sectional study design was used for the study, with data collected from multiple sources using both quantitative and qualitative approaches. Relevant findings included a marked disconnect between family planning/contraceptive knowledge and use. The pills and injectables were the most frequently used, but females in the study population poorly patronised emergency contraception. Supplies of most family planning methods were found to be health facility based, requiring clients to have to necessarily go there for services. Some respondents harboured perceptions that family planning was the responsibility of females alone and that it fuelled promiscuity among female users. Recommendations made include ensuring that health facilities had adequate staff and expertise to provide facility-based family planning services and also to disabuse the minds of community members of the negative perceptions towards family planning
Baseline malaria vector transmission dynamics in communities in Ahafo mining area in Ghana.
BACKGROUND: Malaria vector dynamics are relevant prior to commencement of mining activities. A baseline entomology survey was conducted in Asutifi and Tano (referred to as Ahafo) in the Brong-Ahafo geo-political region of Ghana during preparatory stages for mining by Newmont Ghana Gold Limited. METHODS: Between November 2006 and August 2007, eight Centre for Disease Control light traps were set daily (Monday-Friday) to collect mosquitoes. Traps were hanged in rooms that were selected from a pool of 1,100 randomly selected houses. Types of materials used in construction of houses were recorded and mosquito prevention measures were assessed from occupants. RESULTS: A total of 5,393 mosquitoes were caught that comprised Anopheles gambiae (64.8%), Anopheles funestus (4.2%), as well as Culicines, comprising of Culex (30.4%) and Aedes species (0.6%). The entomological inoculation rate in Asutifi (279 infective bites/person/month) and Tano (487 infective bites/person/month) demonstrate relatively high malaria transmission in Ahafo. The presence or absence of Anopheles vectors in rooms was influenced by the type of roofing material (OR 2.33, 95%CI: 1.29-4.22, p = 0.01) as well as the presence of eaves gaps (OR 1.80, 95%CI: 1.37-2.37, p < 0.01). It was also associated with bed net availability in the room (OR 1.39, 95%CI: 1.08-1.80, p = 0.01). Over 80% of the houses were roofed with corrugated zinc sheets. Over 60% of the houses in Ahafo had no eaves gaps to give access to mosquito entry and exit into rooms and mosquito bed net coverage was over 50%. Other measures used in preventing mosquito bites included; coil (22.1%), insecticide spray (9.4%), repellent cream (4.0%) and smoky fires (1.1%), contributed minimally to individual mosquito preventive measures in impact areas. Similarly, levels of protection; coil (16.9%), insecticide spray (2.8%) and repellent cream (0.3%) for the non-impact areas, depict low individual prevention measures. CONCLUSIONS: The survey identified areas where intensified vector control activities would be beneficial. It also demonstrates that transmission in Asutifi and Tano is high even before the commencement of mining operations. This study serves as baseline information to assess impact of mining activities in relation to future vector control interventions
