THE PREVALENCE OF TUBERCULOSIS IN CATTLE AND THEIR HANDLERS IN NORTH TONGU, VOLTA REGION, GHANA.

BACKGROUND: The need to understand the contribution of bovine tuberculosis (BTB) to the general tuberculosis burden in a poor resource setting is paramount. The aim of this study is to determine the burden of BTB among herdsmen and cattle in the North Tongu district of Volta Region in Ghana. MATERIALS AND METHODS: A cross- sectional study was conducted in the North Tongu District of the Volta Region between the period of October 2011- March 2012. A well-structured questionnaire was used to collect socio-demographic information and possible risk factor information on cattle from participants. Sputum samples from 68 herdsmen and blood samples from 200 cattle belonging to these herdsmen were also collected. Sputum samples were analyzed using Ziehl- Neelsen staining while Anigen Rapid BTB Test was used for Cattle blood samples. RESULTS: Ninety percent (61/68) of respondents were also found to consume fresh milk while 84% (57/68) do not use protective clothing. Of a total of 1580 cattle owned by the herdsmen, 200 cattle consisting of 14 bulls and 186 cows were screened where the prevalence of bovine TB was 19% (38/200) and those affected were all females. All (100%) human sample tested negative for Acid-Fast Bacilli (AFB). However, the seropositivity of cattle and kraal density were statistically associated (p= 0.001). CONCLUSION: Bovine TB is prevalent in cattle in North Tongu district. Although herdsmen indulge in risky lifestyles that expose them to BTB, a zero prevalence of BTB was observed, further study is envisaged using a larger sample size.

THE PREVALENCE OF BRUCELLOSIS IN CATTLE AND THEIR HANDLERS IN NORTH TONGU DISTRICT OF VOLTA REGION, GHANA.

BACKGROUND: Brucellosis is a zoonotic pathogen responsible for great economic losses in most sub-Saharan nations. Although Ghana has successfully implemented the "One Health" initiative for the control of some emerging infectious zoonotic diseases with pandemic potential like Avian Influenza, there is very limited data available on brucellosis especially human brucellosis prevalence. He objective of his study is to determine the seroprevalence of human and bovine brucellosis as well as the predisposing factors at the community level in the North Tongu District of Ghana. MATERIALS AND METHODS: Rose Bengal Plate test (RBPT) was used to analyze blood samples from 178 cattle farmers, and 315 cattle. The positive samples were further confirmed with cELISA. Predisposing factors were determined by questionnaires administered to cattle farmers. All sample sites were geo-referenced. RESULTS: Human and bovine brucellosis seroprevalence using RBPT were 10.1% and 22.9% respectively. Eighty six percent (62/72) of bovine cases were confirmed with ELISA. Delivery assistants were more likely to be infected (p=0.043) with odds ratio of 2.7. Out of the human cases (18), males constituted 88.9%. Ages 11-20 years recorded 77.7% seropositivity whilst cattle drovers represented 44.5% (8/18) of positives. Significant risk factors in cattle were herd size (p=0.037), history of retained placenta (0.000) and abortion (0.005). CONCLUSION: Bovine and human brucellosis is prevalent in North Tongu district, Ghana. Close contact with parturient cows was a major predisposing factor for human infection. Early referral of positive persons to the Hospital for confirmation and treatment is required to comply with the "One Health" initiative on brucellosis and other zoonoses.

Outbreak of cholera in the East Akim Municipality of Ghana following unhygienic practices by small-scale gold miners, November 2010.

BACKGROUND: In October 2010 an outbreak of cholera began among a group of small-scale gold miners in the East-Akim Municipality (EAM), Eastern Region. We investigated to verify the diagnosis, identify risk factors and recommend control measures. METHODS: We conducted a descriptive investigation, active case-search and an unmatched case-control study. A cholera case-patient was a person with acute watery diarrhoea, with or without vomiting in EAM from 1st October to 20(th) November, 2010. Stool from case-patients and water samples were taken for laboratory diagnosis. We performed univariate and bivariate analysis using epi-info version 3.3. RESULTS: Of 136 case-patients, 77 (56.6%) were males, of which 40% were miners or from miners households. Index case, a 20 yr-old male miner from Apapam village reported on October 13(th), and case-patients peaked (18.4%) 20 days later. Attack rate was 2/1000 population with no fatality. Ages ranged from 1-84 years; mean of 34±18 yrs. Age-group 20-29 yrs was mostly affected (30.1%) with Apapam village having most case-patients (19.9%). Vibrio cholera serotype ogawa was isolated from stool samples. The main water source, Birim river was polluted by small-scale miners through defecation, post-defecation baths and sand-washings. Compared to controls, case-patients were more likely to have drunk from Birim-River [OR= 6.99, 95% CI: 2.75-18]. CONCLUSION: Vibrio cholera serotype ogawa caused the EAM cholera-outbreak affecting many young adult-males. Drinking water from contaminated community-wide -River was the major risk factors. Boiling or chlorination of water was initiated based on our recommendations and this controlled the outbreak.

Improving medical records filing in a municipal hospital in Ghana.

BACKGROUND: Medical records are kept in the interest of both the patient and clinician. Proper filing of patient's medical records ensures easy retrieval and contributes to decreased patient waiting time at the hospital and continuity of care. This paper reports on an intervention study to address the issue of misfiling and multiple patient folders in a health facility. DESIGN: Intervention study. SETTING: Municipal Hospital, Goaso, Asunafo North District, Brong Ahafo Region, Ghana. METHODS: Methods employed for data collection were records review, direct observation and tracking of folders. Interventions instituted were staff durbars, advocacy and communication, consultations, in-service trainings, procurement and monitoring. Factors contributing to issuance of multiple folders and misfiling were determined. Proportion of multiple folders was estimated. RESULTS: Results revealed direct and indirect factors contributing to issuance of multiple patient folders and misfiling. Interventions and monitoring reduce acquisition of numerous medical folders per patient and misfiling. After the intervention, there was significant reduction in the use of multiple folders (i.e., overall 97% reduction) and a high usage of single patient medical folders (i.e., 99%). CONCLUSION: In conclusion, a defined medical records filing system with adequate training, logistics and regular monitoring and supervision minimises issuance of multiple folders and misfiling.

Economic burden of motorcycle accidents in Northern Ghana.

BACKGROUND: Motorcycles are the most popular means of transportation in northern Ghana, and their accidents are major causes of out-patient attendance and admissions in the Bolgatanga Municipality. OBJECTIVE: This paper estimates the economic burden of motorcycle accidents in the Bolgatanga Municipality in Northern Ghana. DESIGN: Retrospective cross-sectional cost study. METHODS: Data were collected from Drivers and Vehicle Licensing Authority, the Police, health facilities and motorcycle accident victims. Both quantitative and qualitative approaches were used for data collection. Cost analysis was based on the standard road accident cost conceptual framework. RESULTS: Ninety-eight percent of vehicles registered in the municipality in 2004 - 2008 were motorcycles. The motorcycles were significantly more than the cars registered. The economic burden of motorcycle accidents was estimated to be about US$1.2 million, of which, 52% were accident-related costs (i.e. property damage and administration) and 48% casualty-related costs (i.e. medical costs, out-of-pocket expenses, lost labour outputs, intangible costs and funeral expenses). Most motorcycle accident victims were in their productive ages and were males. Only a third of the motorcycles were insured. Majority of the riders (71%) did not possess valid driving license and would want to avoid the police. Main motorcycle injuries were head injuries, fractures, lacerations and contusions. Majority of the accidents were caused by lack of formal motorcycle riding training, abuse of alcohol, unrestrained animals and donkey carts. CONCLUSION: Motorcycle accidents could be reduced through law enforcement, continuous mass education and helmet use.

Implementing Integrated Disease Surveillance and Response: Four African countries' experience, 1998-2005.

The Integrated Disease Surveillance and Response (IDSR) strategy was developed by the Africa Regional Office (AFRO) of the World Health Organisation (WHO) and proposed for adoption by member states in 1998. The goal was to build WHO/AFRO countries' capacity to detect, report and effectively respond to priority infectious diseases. This evaluation focuses on the outcomes in four countries that implemented this strategy. Major successes included: integration of the surveillance function of most of the categorical disease control programmes; implementation of standard surveillance, laboratory and response guidelines; improved timeliness and completeness of surveillance data and increased national-level review and use of surveillance data for response. The most challenging aspects were: strengthening laboratory networks; providing regular feedback and supervision on surveillance and response activities; routine monitoring of IDSR activities and extending the strategy to sub-national levels.

A three year follow-up of chemotherapy with praziquantel in a rural Zambian community endemic for schistosomiasis mansoni.

A resurvey for schistosomiasis mansoni was carried out in a community 2 years after chemotherapy with praziquantel was stopped. Data on infection status, morbidity, subjective symptoms, and liver and spleen enlargement were collected from participants. Results show that prevalence of Schistosoma mansoni infection and subjective symptoms of morbidity have returned to pretreatment levels. However, the population mean egg output remained low. Liver and spleen sizes in individuals who received treatment have shown a further decline compared to 2 years before. We conclude that selective mass chemotherapy with praziquantel can give the community as a whole a respite from schistosomiasis morbidity for at least 2 years despite an increase in prevalence.

Reduction in prevalence, intensity of infection and morbidity due to Schistosoma mansoni infection in a community following treatment with praziquantel.

Five hundred and twenty-three individuals from an area endemic for Schistosoma mansoni infection were followed for a 16 month period in a population-based study in rural Zambia. Those found infected in each of five surveys were treated with praziquantel (40 mg kg-1 body weight). Data on prevalence, intensity of infection and morbidity (intestinal symptoms and liver and spleen enlargements) were also gathered. At the end of the study, prevalence had fallen from 64.8% to 11.5%, intensity of infection had dropped from 28.2 to 0.5 eggs per gram of stool (geometric means) and morbidity showed marked reduction.

Profiles of heterophile antibody to various mammalian erythrocytes in rural populations of Zambia.

Heterophile antibodies to sheep red blood cells (SRBC), rabbit red blood cells (RRBC), horse red blood cells (HRBC), murine (rat) red blood cells (MRBC) were investigated in a total of 416 serum samples from two rural areas of Zambia where major parasitic diseases are endemic. Distribution of antibody titers to RRBC were significantly different between the two study areas, whereas titers to SRBC were not significantly different. Sheep RBC's did not reveal a uniform consistent difference between the two communities with respect to schistosomiasis and malaria. Rabbit erythrocytes showed significant differences (P less than 0.05) between parasitologically positive and negative samples for schistosomiasis and malaria, respectively. No significant difference was observed between sexes, although females generally have a slightly higher titer for both SRBC and RRBC than males. No significant agglutinins were detected to HRBC and BRBC. Agglutinins to MRBC were generally too high to be of any differential value. It is suggested that sheep and rabbit erythrocytes might be useful probes for evidence of exposure to parasites and assessment of humoral immunologic status, albeit nonspecific. Further, it is inferred that the incidence of infectious mononucleosis in this region is rather low. A controlled investigation into the distribution of E-B viruses is suggested to explain absence of I-M-like agglutinins in a region climatically conductive to existence of arborviruses in general, and the E-B virus group in particular.
