Outbreak investigation and enhanced contact tracing of novel coronavirus disease 2019 (COVID-19), Ablekuma North Municipality, Greater Accra, Ghana

Introduction: After Ghana recorded its first two cases of COVID-19, other cases were subsequently identified in other parts of the country. The Ablekuma North Municipal Health Directorate was notified of a resident who reported to Korle-Bu Teaching Hospital on March 29, 2020 with fever, shortness of breath, general weakness, cough, chest pain. We investigated the report to estimate the magnitude of cases, to determine the secondary infection rate and to institute control and preventive measures. Methods: We conducted active case search using Ghana Health Service interim guideline for COVID-19 case investigation and management in Ablekuma North Municipality from April-July 31, 2020. We interviewed and collected samples of contacts and at-risk groups in affected households using collector for ArcGis and case investigation form. We summarized information of COVID-19 cases on our line list after samples have been confirmed. We analyzed data using Microsoft Excel 2016 and Stata 15, and presented as frequency and proportions. Results: The municipality recorded 213 cases with four deaths (Case fatality Rate=1.88%). The attack rate was 111.47 per 100,000 (213/ 191,075). Males were 135 (63.38%). The median age of case-patients was 27 years (interquartile range: 19 - 36years). Majority were students; 64 (30.05%). Most of the cases 89.20% (190/213) were asymptomatic. The median time between sample collection and release of laboratory results was 15 days (range: 4 - 22days). This response was a multi-sectorial approach, involving the Ministry of Health and the Ghana Health Service, Municipal Assembly, National Security Ministry, Ministry of Communication, Ministry of Information, and other government agencies. Conclusion: All confirmed cases were investigated. The attack rate was relatively high but low case fatality rate in the municipality. Strengthening laboratory capacity to test, to early report results is recommended. Lessons in handling cases indicate the need to sustain multi-sectorial collaboration to fight the outbreak

Management of dog bites by frontline service providers in primary healthcare facilities in the Greater Accra Region of Ghana, 2014–2015

Abstract Background Dog bites are common in developing countries including Ghana, with the victims often being children. Although some breeds of dogs have been identified as being more aggressive than others, all dog bites carry a risk of infection. Immediate and initial assessment of the risk for tetanus and rabies infection with appropriate interventions such as wound management and subsequent selection of prophylactic antibiotics are essential in the management of dog bites. This study examined the management of patients with dog bites by frontline service providers at primary healthcare facilities in the Greater Accra Region, Ghana. Methods We conducted a cross-sectional study in 66 public health facilities in the Greater Accra Region from July 2014 to April 2015. Up to four frontline service providers were randomly selected to participate from each facility. A structured questionnaire was administered to all consenting participants. Continuous variables were presented as means and standard deviations. The frontline service providers’ knowledge was assessed as a discrete variable and values obtained presented as percentages and proportions. The chi-square test of proportions was used to determine any significant associations between the various categories of the frontline service providers and their knowledge about the management of rabies. Results Regarding the frontline service providers’ knowledge about rabies, 57.8% (134/232) were correct in that the rabies virus is the causative agent of rabies, 39.2% (91/232) attributed it to a dog bite, 2.6% (6/232) did not know the cause, and one person (0.4%) attributed it to the herpes virus. Only 15.5% (36/232) knew the incubation period in dogs and the period required to observe for signs of a rabies infection. With respect to the administration of rabies immunoglobulin, 42.2% (98/232) of the frontline service providers did not know how to administer it. Of the facilities visited, 76% (50/66) did not have the rabies vaccines and 44% (102/232) of frontline service providers did not know where to get the rabies vaccines from. Most of the service providers (87.9%; 204/232) had never reported either a dog bite or a suspected case of rabies. Overall, there was gross underreporting of dog bites and suspected rabies cases at public healthcare facilities in the Greater Accra Region of Ghana. Conclusions In view of the high morbidity and mortality associated with bites from rabid dogs and the poor knowledge and practices of frontline service providers, there is an urgent need for capacity-building such as training in the management of dog bites and subsequent potential rabies infection

Large cholera outbreak in Brong Ahafo Region, Ghana

Abstract Background A nationwide outbreak of Vibrio cholerae occurred in Ghana in 2014 with Accra, the nation’s capital as the epi-center. The outbreak spread to the Brong Ahafo Region (BAR) which is geographically located in the middle of the country. In this region a review of data collected during the outbreak was carried out and analyzed descriptively to determine the hot spots and make recommendations for effective response to future outbreaks. Methods A review of patient records and line lists of cases of cholera reported in all hospitals during the period of the outbreak (July–December 2014) was conducted. Hospitals used IDSR (Integrated Disease Surveillance and Response system) standard case definitions to detect and report cases for management. The GPS coordinates of all districts and health facilities were collected and utilized in the construction of spot maps. We also obtained populations (denominators) from the BAR Health surveillance unit of the Ghana Health Service. All the data thus collected was analyzed descriptively and expressed as frequencies and rates. Results A total of 1035 cases were reported, 550 (53.4%) were males and the rest females. Their ages ranged from 1 to 95 years; (mean age of 28.2 ± 19.6 years). The most affected (23.5%) was the 20–29 year old age group. On the 30th July, 2014, a 26 year old male (recorded as the index case of the cholera outbreak in the Brong Ahafo region) with a history of travel from Accra reported to the Nkoranza district hospital with a history of symptoms suggestive of cholera. The reporting of cholera cases reached their peak (17.3%) in week 15 of the outbreak (this lasted 25 weeks). An overall attack rate of 71/100,000 population, and a case fatality rate of 2.4% was recorded in the region. Asutifi South district however recorded a case fatality of 9.1%, the highest amongst all the districts which recorded outbreaks. The majority of the cases reported in the region were from Atebubu-Amanten, Sene West, Pru, and Asunafo North districts with 31.1, 26.0, 18.2 and 9.9% respectively. Vibrio cholerae serotype O1 was isolated from rectal swabs/stool samples tested. Conclusion Vibrio cholerae serotype O1 caused the cholera-outbreak in the Brong Ahafo Region and mainly affected young adult-males. The most affected districts were Atebubu-Amanten, Sene west, Pru (located in the eastern part of the region), and Asunafo North districts (located in the south west of the region). Case Fatality Rate was higher (2.4%) than the WHO recommended rate (<1%). Active district level public health education is recommended on prevention and effective response for future outbreaks of cholera

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

Spatio-temporal distribution of under-five malaria morbidity and mortality hotspots in Ghana, 2012 – 2017: a case for evidence-based targeting of malaria interventions

Introduction: The spatiotemporal variation in malaria burden underpins the need for targeted malaria interventions. Despite the scale-up of malaria control interventions in Ghana, malaria remains the leading cause of hospital admissions and deaths among children below 5 years (U5). We described spatiotemporal distribution of U5 malaria morbidity and mortality from 2012 to 2017 to provide evidence for deployment of specific malaria interventions to regions of hotspots in Ghana. Methods: We conducted a retrospective review of district-level malaria surveillance data from 2012 to 2017. We obtained confirmed U5 malaria case and population data for all districts in Ghana, and computed yearly smoothed malaria incidence and mortality rates. Hotspot analysis was performed using GeoDa’s Global and Local Moran I tests of spatial autocorrelation. Results: Overall, 8,132,769 U5 malaria cases and 5,932 deaths were reported, with case fatality rate of 0.1%. Under-five malaria incidence increased from 16.4% in 2012 to 31.3% in 2017, and the mortality rate per 100,000 decreased from 30.2 in 2012 to 6.1 in 2017. We found variation in morbidity hotspots from 8 to 23 in the western, south-western and north-eastern areas of the country each year, and six persistent mortality hotspots in the north-eastern areas. Conclusion: Over the review period, U5 malaria morbidity increased while mortality decreased. Variability in morbidity hotspots occurred across the western and northern regions unlike persistence of mortality hotspots in the north-eastern region. We recommend that the National Malaria Control Program systematically deploys preventive and case management interventions to areas of hotspots and also conduct a further evaluation to identify the causes of high mortality in the northeastern areas

Under-reporting of adverse drug reactions: Surveillance system evaluation in Ho Municipality of the Volta Region, Ghana.

BackgroundAdverse Drug Reactions (ADRs) can occur with all medicines even after successful extensive clinical trials. ADRs result in more than 10% of hospital admissions worldwide. In Ghana, there has been an increase of 13 to 126 ADR reports per million population from 2012 to 2018. ADR Surveillance System (ADRSS) also known as pharmacovigilance has been put in place by the Ghana Food and Drugs Authority (FDA) to collect and manage suspected ADR reports and communicate safety issues to healthcare professionals and the general public. The ADRSS in Ho Municipality was evaluated to assess the extent of reporting of ADRs and the system's attributes; determine its usefulness, and assess if the ADRSS is achieving its objectives.MethodsWe evaluated the ADRSS of the Ho Municipality from January 2015 to December 2019. Quantitative data were collected through interviews and review of records. We adapted the updated CDC guidelines to develop interview guides and a checklist for data collection. Attributes reviewed included simplicity, data quality, acceptability, representativeness, timeliness, sensitivity, predictive value positive and stability.ResultsWe found a total of 1,237 suspected ADR during the period, of which only 36 (3%) were reported by healthcare professionals in the Ho Municipality to the National Pharmacovigilance Centre (NPC). Only 43.9% of health staff interviewed were familiar with the ADRSS and its reporting channel. Staff who could mention at least one objective of the ADRSS were 34.2%, and 12.2% knew the timelines for reporting ADR. Reports took a median time of 41 (IQR = 25, 81) days from reporter to NPC. Reports sent on time constituted 37.5%. Fully completed case forms constituted 77.1% and the predictive value positive (PVP) was 20%. About 53% of ADRs were reported for female patients. Up to 88.9% of ADRs were classified as drug related. Anti-tuberculosis agents and other antibiotics constituted (40.6%) and (18.8%) of all reports. The ADRSS was not integrated into the disease surveillance and response system of Ghana's Health Service and so was not flexible to changes. A dedicated ADR surveillance officer in regions helped with the system's stability. Data from Ghana feeds into a WHO database for global decision making.ConclusionsThere was under-reporting of ADRs in the Ho Municipality from January 2015 to December 2019. The ADR surveillance system was simple, stable, acceptable, representative, had a strong PVP but was not flexible or timely. The ADRSS was found useful and partially met its objectives

Design and deployment of relational geodatabase on mobile GIS platform for real-time COVID-19 contact tracing in Ghana

This study reviewed the design and deployment of relational geodatabase on mobile GIS application, using collector for ArcGIS and survey 123 for ArcGIS platforms for COVID-19 contact tracing in Ghana during the lockdown. The study assessed whether cases spread by physical neighborhood contacts, defined by a 2km buffer of initial known 60 cases location. The application was deployed on the android tablet, which was used by field workers. Application Post-deployment review shows that from 30th March to 4th April 2020, 828 samples were collected with 34 confirmed cases, of which 61% occurred outside the 2km buffer. From 1-30 April 2020, 8,748 individuals with 16,087 contacts were tested within the physical neighbourhoods, 2.4% turned positive. Similarly, 7,501 individuals with 17,071 contacts were tested outside the physical neighbourhoods with 4.3% positives.&nbsp; Results suggest that more infections occurred outside the case’s physical neighbourhoods possibly due to; (1) existence of unknown cases prior to lockdown; (2) cases were moving outside their physical neighborhood and infecting others; (3) panic movements of cases within the 3 days window between announcement and enforcement of lockdown; (4) movement of cases into the country through unapproved routes.&nbsp; New cases were identified outside the lockdown areas, which could not be explained. This study raises questions about (1) the understanding of the mode of spread of the virus (2) the implementation of the lockdown, including the geographic coverage and timing. It is recommended that future decisions on contact tracing and lockdown should be guided by an understanding of the disease geography.&nbsp

Pneumococcal meningitis outbreak and associated factors in six districts of Brong Ahafo region, Ghana, 2016

Abstract Background Meningitis, a disease of the Central Nervous System is described as inflammation of the covering of the brain and spinal cord (meninges). It is characterised by fever, severe headache, nausea, vomiting, stiff neck, photophobia, altered consciousness, convulsion/seizures and coma. In December, 2015, twelve suspected cases of meningitis were reported in Tain district in Brong Ahafo region (BAR). Subsequently, dozens of suspected cases were hospitalized in five district hospitals in BAR. We investigated to determine the magnitude, causative agent and risk factors for the disease transmission. Methods A community-based 1:2 case-control study (with 126 individuals) was conducted form 10/12/15 to 26/4/16 in 27 districts of Brong-Ahafo Region, Ghana. We defined suspected meningitis cases as people presenting with sudden headache and fevers (Temp> 38.0 °C) in combination with one of the following signs: neck stiffness, altered consciousness, convulsions, bulging fontanelle (infants) and other meningeal signs. Controls were selected from the same neighbourhood and defined as individuals with no overt meningitis signs/symptoms. We collected CSF samples and performed serological testing using Pastorex-Meningitis-Kit and culture for bacterial isolation. Moreover, structured questionnaires were used to collect data on socio-demographics, living conditions, health status and other risk factors. We conducted univariate data analysis and logistic regressions to study disease-exposure associations using Stata 15. Results A total of 969 suspected cases with 85 deaths (CFR = 9.0%) were recorded between December, 2015 and March, 2016. Majority, 55.9% (542/969) were females aged between 10 months-74 years (median 20 years, IQR; 14-34). Of the 969 cases, 141 were confirmed by Laboratory test with Streptococcus pneumoniae identified as the causative agent. Cases were reported in 20 districts but 6 of these districts reported cases above threshold levels. The outbreak peaked in week 6 with 178 cases. Overall attack rate (AR) was 235.0/100,000 population. District specific ARs were; Tain; 143.6/100,000, Wenchi; 110.0/100,000, Techiman; 46.6/100,000, Jaman North; 382.3/100,000 and Nkoranza South; 86.4/100,000. Female and male specific ARs were 251.3/100,000 and 214.5/100,000 respectively. Age group 10-19 years were most affected 33.8% (317/940). We identified sore throat [aOR = 5.2, 95% (CI 1.1-26.1)] and alcohol use [aOR = 9.1, 95%(CI 1.4-55.7)] as factors associated with the disease transmission. Conclusion Meningitis outbreak due to Streptococcus pneumoniae was established in BAR. Upper respiratory tract infection and alcohol use were associated with the outbreak. Mass campaigns on healthy living habits, signs and symptoms of meningitis as well as the need for early reporting were some of the control measures instituted. Moreover, we recommend Pneumococcal vaccination in BAR to prevent future outbreaks

Frequency and management of maternal infection in health facilities in 52 countries (GLOSS): a 1-week inception cohort study

Background Maternal infections are an important cause of maternal mortality and severe maternal morbidity. We report the main findings of the WHO Global Maternal Sepsis Study, which aimed to assess the frequency of maternal infections in health facilities, according to maternal characteristics and outcomes, and coverage of core practices for early identification and management. Methods We did a facility-based, prospective, 1-week inception cohort study in 713 health facilities providing obstetric, midwifery, or abortion care, or where women could be admitted because of complications of pregnancy, childbirth, post-partum, or post-abortion, in 52 low-income and middle-income countries (LMICs) and high-income countries (HICs). We obtained data from hospital records for all pregnant or recently pregnant women hospitalised with suspected or confirmed infection. We calculated ratios of infection and infection-related severe maternal outcomes (ie, death or near-miss) per 1000 livebirths and the proportion of intrahospital fatalities across country income groups, as well as the distribution of demographic, obstetric, clinical characteristics and outcomes, and coverage of a set of core practices for identification and management across infection severity groups. Findings Between Nov 28, 2017, and Dec 4, 2017, of 2965 women assessed for eligibility, 2850 pregnant or recently pregnant women with suspected or confirmed infection were included. 70·4 (95% CI 67·7–73·1) hospitalised women per 1000 livebirths had a maternal infection, and 10·9 (9·8–12·0) women per 1000 livebirths presented with infection-related (underlying or contributing cause) severe maternal outcomes. Highest ratios were observed in LMICs and the lowest in HICs. The proportion of intrahospital fatalities was 6·8% among women with severe maternal outcomes, with the highest proportion in low-income countries. Infection-related maternal deaths represented more than half of the intrahospital deaths. Around two-thirds (63·9%, n=1821) of the women had a complete set of vital signs recorded, or received antimicrobials the day of suspicion or diagnosis of the infection (70·2%, n=1875), without marked differences across severity groups. Interpretation The frequency of maternal infections requiring management in health facilities is high. Our results suggest that contribution of direct (obstetric) and indirect (non-obstetric) infections to overall maternal deaths is greater than previously thought. Improvement of early identification is urgently needed, as well as prompt management of women with infections in health facilities by implementing effective evidence-based practices
