Motivations and challenges of community-based surveillance volunteers in the northern region of Ghana.
Community health workers (CHWs) are an important element of many health systems and programmes for the promotion and delivery of a wide range of health interventions and disease surveillance. Understanding the motivation and retention of CHWs is recognized as essential but there are few data from sub-Saharan Africa. This qualitative study explored factors that motivate, and the challenges faced by community-based surveillance volunteers (CBSVs) in the Northern Region of Ghana through semi-structured interviews with 28 CBSVs, 12 zonal coordinators, nine Ghana Health Service (GHS) sub-district level staff, ten GHS district level staff and two GHS regional level staff in the administrative capital. The community emerged as an important motivating factor in terms of altruism, a sense of duty to the community and gaining community respect and pride. This was enhanced by community selection of the volunteers. Major challenges included incorrect community perceptions of CBSVs, problems with transportation and equipment, difficulties conducting both volunteer and farm work and late or lack of payment for ad hoc tasks such as National Immunization Days. Most CBSVs recognized that they were volunteers, understood the constraints of the health system and were not demanding remuneration. However, CBSVs strongly desired something tangible to show that their work is recognized and appreciated and described a number of low cost items that could be used. They also desired equipment such as raincoats and identifiers such as tee-shirts and certificates
Acute childhood diarrhoea in northern Ghana: epidemiological, clinical and microbiological characteristics
<p>Abstract</p> <p>Background</p> <p>Acute diarrhoea is a major cause of childhood morbidity and mortality in sub-Saharan Africa. Its microbiological causes and clinico-epidemiological aspects were examined during the dry season 2005/6 in Tamale, urban northern Ghana.</p> <p>Methods</p> <p>Stool specimens of 243 children with acute diarrhoea and of 124 control children were collected. Patients were clinically examined, and malaria and anaemia were assessed. Rota-, astro-, noro- and adenoviruses were identified by (RT-) PCR assays. Intestinal parasites were diagnosed by microscopy, stool antigen assays and PCR, and bacteria by culturing methods.</p> <p>Results</p> <p>Watery stools, fever, weakness, and sunken eyes were the most common symptoms in patients (mean age, 10 months). Malaria occurred in 15% and anaemia in 91%; underweight (22%) and wasting (19%) were frequent. Intestinal micro-organisms were isolated from 77% of patients and 53% of controls (<it>P </it>< 0.0001). The most common pathogens in patients were rotavirus (55%), adenovirus (28%) and norovirus (10%); intestinal parasites (5%) and bacteria (5%) were rare. Rotavirus was the only pathogen found significantly more frequently in patients than in controls (odds ratio 7.7; 95%CI, 4.2–14.2), and was associated with young age, fever and watery stools. Patients without an identified cause of diarrhoea more frequently had symptomatic malaria (25%) than those with diagnosed intestinal pathogens (12%, <it>P </it>= 0.02).</p> <p>Conclusion</p> <p>Rotavirus-infection is the predominant cause of acute childhood diarrhoea in urban northern Ghana. The abundance of putative enteropathogens among controls may indicate prolonged excretion or limited pathogenicity. In this population with a high burden of diarrhoeal and other diseases, sanitation, health education, and rotavirus-vaccination can be expected to have substantial impact on childhood morbidity.</p
Why is dracunculiasis eradication taking so long?
The long time needed for global eradication of dracunculiasis (Guinea worm disease) was not anticipated at the outset. The successful eradication of smallpox in 10 years compares with the target date set in 1985 for dracunculiasis eradication - 1995. Seventeen years after that date, transmission continues. Why? Various factors are responsible, mainly lack of resources, or resources ineffectively used. The example of Ghana, where the programme stagnated for a decade, sheds light on this delay. When more resources were put into Ghana's programme in 2007, transmission of the disease was interrupted in 3 years. The variable success of dracunculiasis eradication in different countries provides lessons for future disease eradication programmes
Field Evaluation of a Rota- and Adenovirus Immunochromatographic Assay Using Stool Samples from Children with Acute Diarrhea in Ghanaâ–¿
We evaluated the Rida Quick rotavirus/adenovirus Combi rapid immunochromatographic test (ICT) under field conditions with Ghanaian children with acute diarrhea. Compared to PCR results, sensitivities and specificities were 75% and 95% for rotavirus and 22% and 84% for adenovirus. In resource-poor settings, ICTs may help to overcome difficulties in the diagnosis of rotavirus infection
