Poliovirus antibody levels and lameness among individuals in three regions of Ghana

Introduction Ghana recorded the last case of poliomyelitis caused by wild poliovirus in 2008 and the country was declared polio-free in 2015. Polio-neutralizing-antibody levels in the population of three geographically representative regions of Ghana was determined, to identify possible immunity gaps. Methods Cross-sectional, hospital (1–70 years old) and school (primary, 1–15 years old)-based studies were undertaken in three regions in 2016. Individuals who visited the three teaching hospitals of the regions and were referred for haematology investigations were invited to participate in our study. Neutralizing-antibody titers to polio serotypes P1, P2, and P3 were assayed by WHO-standards. Antibody titers of ≥8 were considered protective. In the school lameness survey, clinical and epidemiological data were obtained from parents and their lamed children. Bivariate and multivariate analyses were conducted on subject characteristics, to assess potential factors for failure to seroconvert. P-values < 0.05 were considered statistically significant. Results Neutralizing-antibodies against poliovirus types 1, 2 and 3 were detected in 86% (264/307), 84% (258/307) and 75% (230/307) of the samples, respectively. Overall, 60.1% (185/307) were seropositive for the three polio serotypes and 2.9% (9/307) were seronegative. Polio neutralizing-antibodies (P1and P2) decreased with age (p < .001). Low seroprevalence of polio-neutralizing-antibodies was significantly associated with low school attendance of mothers (p < .001). Prevalence of residual paralysis was <1.0/1,000 among the school children. Conclusion Our study population is moderately protected against the three poliovirus serotypes. However, immunity appears to be lower with a higher age and low mother’s education. This may suggest the need for young-adult booster-dose to minimize the risk of wild poliovirus infection

Evaluation of the enhanced meningitis surveillance system, Yendi municipality, northern Ghana, 2010–2015

Abstract Background Meningitis is the inflammation of the meninges of the brain and or spinal cord. Global mortality rates vary from 2% to 30%. Epidemic meningitis remains a public health concern along the meningitis belt of Africa. Despite the operation of an enhanced meningitis surveillance system in Ghana, institutional mortality rates are estimated to range from 36% to 50%. In 2014, Yendi recorded 83 confirmed cases; with focal epidemics in some sub-municipals. We evaluated the system over a five-year period to find out whether it was achieving its objectives of systematic collection and analyses of data for the prevention or early detection of meningitis epidemics. Methods We used cross-sectional design. Both qualitative and quantitative data from Yendi Municipality between January 2010 and December 2015 were collected and analyzed. The updated guidelines for evaluating surveillance systems from Centers for Disease Control and Prevention were used. Content analysis was performed on the responses of key informants. Surveillance data was analyzed using MS-Excel. Results Fifteen healthcare workers were interviewed. For the period under evaluation, the annual incidence of meningitis ranged from 1.6/100,000 in 2012 to 62.6/100,000 in 2014. The average case fatality rate for the period was 8.3%. The system was sensitive, representative, and acceptable. The predictive value positive was 100% from 2010 to 2014 and 63.3% in 2015. Data quality was good, but timeliness of reporting was poor. Conclusions The enhanced meningitis surveillance system in Yendi Municipality is achieving most of its objectives. However, financial constraints and poor personnel motivation pose threats to the sustainability of the system

Bacteriological profile and antibiotic susceptibility pattern of common isolates of neonatal sepsis, Ho Municipality, Ghana-2016

Abstract Background Globally, 4 million neonates die annually, with one-third of such deaths occurring as a result of infections. In 2011, there were 7.2million deaths in children below 5 years globally, and a proportion of 40% of these deaths occurred in neonates. Sepsis was reported to account for one-third of these deaths. Presently, multidrug antibiotic resistance is rapidly increasing in Neonatal Intensive Care Units (NICUs), particularly in developing countries and poses a threat to public health. The change in these organisms has been reported to vary across regions, between health facilities and even within the same facility. Continuous surveillance is required to inform antibiotic choice for neonatal sepsis management. We identified the common causative organisms of neonatal sepsis and their antibiotic susceptibility pattern in the Ho municipality. Method A cross sectional study was conducted in the Ho municipality from January to May, 2016. A semi-structured questionnaire was used to collect socio-demographic data from mothers of neonates with clinically suspected of sepsis. Clinical data of both mothers and neonates were extracted from case notes. A 2 ml volume of blood was also taken from neonates and dispensed into a 20 ml mixture of thioglycollate fluid broth and tryptone soy broth for culture and antibiotic susceptibility pattern determined. Results Out of the 150 clinically suspected neonatal sepsis cases, 91 (60.7%) were males. The Median gestational week was 38 (IQR: 36–39) and Median birthweight was 3.0 kg (IQR 2.5–3.4). The prevalence of culture positive sepsis was 17.3% of the 150 suspected cases. A total of 26 different pathogens were isolated, of which gram positive organisms had a preponderance of 18 (69%) over gram negative organisms 8 (31%). Staphylococcus epidermidis was the most common 14 (53.8%) isolate identified. There was a single isolate (4%) each of Proteus mirabilis and Escherichia coli identified. All the isolates identified showed 100% resistance to ampicillin. Conclusion The prevalence of culture proven sepsis was 17.3% and Staphylococcus epidermidis was the most common isolate identified. Pathogens isolated were resistant to the first line drugs for management of neonatal sepsis. Hence, the need for a review of first line drug for empirical treatment in neonatal sepsis

Epidemiological link of a major cholera outbreak in Greater Accra region of Ghana, 2014

Abstract Background Cholera remains an important public health challenge globally. Several pandemics have occurred in different parts of the world and have been epidemiologically linked by different researchers to illustrate how the cases were spread and how they were related to index cases. Even though the risk factors associated with the 2014 cholera outbreak were investigated extensively, the link between index cases and the source of infection was not investigated to help break the transmission process. This study sought to show how the index cases from various districts of the Greater Accra Region may have been linked. Methods We carried out a descriptive cross sectional study to investigate the epidemiological link of the 2014 cholera outbreak in the Greater Accra region of Ghana. An extensive review of all district records on cholera cases in the Greater Accra region was carried out. Index cases were identified with the help of line lists. Univariate analyses were expressed as frequency distributions, percentages, mean ± Standard Deviation, and rates (attack rates, case-fatality rates etc.) as appropriate. Maps were drawn using Arc GIS and Epi info software to describe the pattern of transmission. Results Up to 20,199 cholera cases were recorded. Sixty percent of the cases were between 20 and 40 years and about 58% (11,694) of the total cases were males. Almost 50% of the cases occurred in the Accra Metro district. Two-thirds of the index cases ate food prepared outside their home and had visited the Accra Metropolis. Conclusions The 2014 cholera outbreak can be described as a propagated source outbreak linked to the Accra Metropolis. The link between index cases and the source of infection, if investigated earlier could have helped break the transmission process. Such investigations also inform decision-making about the appropriate interventions to be instituted to prevent subsequent outbreaks

Factors associated with culture proven neonatal sepsis in the Ho municipality 2016

Introduction:&nbsp;Neonatal Sepsis (NNS) is a public health problem which causes death or disability unless appropriate antibiotic treatment is given promptly. Globally, sepsis is an important cause of morbidity and mortality in neonates despite recent progress in health care delivery. We assessed the factors associated with culture proven sepsis among neonates in the Ho Municipality, Ghana. Methods:&nbsp;a cross-sectional study was conducted in two public hospitals in the Ho Municipality between January and May, 2016. All neonates who were clinically suspected with sepsis in the Neonatal Intensive Care Unit (NICU) and their mothers were recruited. A 2ml blood sample was taken aseptically and dispensed into a mixture of thioglycollate and tryptone soy broth in a 1:10 dilution and microbiological procedures performed. Case notes of both neonates and their mothers were reviewed and interviews conducted to collect both clinical and socio-demographic data. We determined the factors associated with culture proven neonatal sepsis using logistic regression model and statistical significance was determined at 95% confidence intervals. Results:&nbsp;out of 150 neonates, 26 (17%) had laboratory confirmed sepsis. The most common pathogen isolated was Staphylococcus epidermidis 14, (54%). Neonates whose mothers were primigravida (OR=2.74; 95% CI:1.12-6.68), and those who attended antenatal clinics (ANC) fewer than three schedules (OR=2.90; 95% CI:1.06-7.96) had higher odds of developing culture proven sepsis. Conclusion:&nbsp;neonates who were the first babies of their mothers were more likely to develop laboratory confirmed sepsis. Also, neonates of mothers who attended ANC less than 3 times were more likely to develop laboratory confirmed sepsis. High index of suspicion is required to diagnose neonatal sepsis among neonates of primigravida mothers and mothers who attend fewer than three ANC schedules

The effect of malaria prevention and control interventions on malaria morbidity among children under 5 years and pregnant women in Kintampo North Municipality, Ghana

Background: Malaria prevention and control interventions have been scaled-up in the last decade in Ghana. We analysed the malaria surveillance data to assess the trends and the association between some malaria prevention interventions and malaria incidence in Kintampo North Municipality (KNM). Methods: We extracted data on malaria indicators and interventions from the District Health Information Management System 2 database for 2012–2016. Proportions and cumulative incidence of malaria episodes were computed using STATA 14 software. We performed correlation analysis between malaria interventions and malaria morbidity. We used linear regression models to determine the association between Long-Lasting Insecticide-treated Nets (LLINS) distribution, Intermittent Preventive Treatment in Pregnancy (IPTp) and episodes of malaria in children &lt;5 years old and pregnant women. Results: A total of 280,890 episodes of malaria were recorded in the KNM from 2012–2016. Of the total malaria episodes, 64,953 (23.1%) were children &lt;5 years and 57.5% (161,486/280,890) were females. The incidence of malaria in KNM declined from 650/1,000 population in 2012 to 444/1,000 population in 2016. The proportion of confirmed malaria increased from 35.2% in 2012 to 80.7% in 2015, and subsequently declined to 77.5% in 2016. The malaria Case Fatality Rate decreased by 65% in 2012 to 0.04% (16/37646) in 2016. Long Lasting Nets distribution to children showed a weak negative linear relationship with malaria morbidity in children &lt;5 years (R= –0.20). IPTp1, IPTp2 showed a weak negative linear relationship with malaria morbidity in pregnancy, IPTp3 showed a weak positive linear relationship while IPTp4 and IPTp5 showed a negative moderate linear relationship with malaria morbidity in pregnancy. A unit increase in LLINs distribution to pregnant women was significantly associated with a reduction in malaria in pregnancy episodes by 0.21 (R2 = 0.19, 95% CI: -0.3 ─ -0.7). The IPTp first dose (IPTp1) coverage declined from 75.5% in 2012 to 69.0% in 2014, but rose to 80.9% in 2016. IPTp5 (fifth dose) increased from 0.7% in 2014 to 4.8% in 2016. A percentage increase in the coverage of only IPTp4 was associated with a reduction of malaria in pregnancy by two episodes (R2 = 0.34, 95% CI = ─ 1.68 – (─0.78). Conclusion: Malaria morbidity trend declined in the municipality. Increase coverage in LLINs and IPTp were associated with declines in malaria episodes in children &lt;5years old and pregnancy women. Coverage of IPTp4 and IPTp5 were relatively low. Health staff should intensify promotion of the use of malaria prevention interventions among pregnant women and children &lt; 5 years old. Midwives should promote uptake of optimal IPTp doses through health education and community antenatal outreach services
