Item Biosecurity measures to reduce influenza infections in military barracks in Ghana(BioMed Central, BMC Research Notes, 2015-01) Agbenohevi, P.G.; Odoom, J.K.; Bel-Nono, S.; Nyarko, E.O.; Alhassan, M.; Rodgers, D.; Danso, F.; Suu-Ire, R.D.; Bonney, J.H.K; Aboagye, J.; Kronmann, K.C.; Duplessis, C.; Oyofo, B.A.; Ampofo, W.K.Background Military barracks in Ghana have backyard poultry populations but the methods used here involve low biosecurity measures and high risk zoonosis such as avian influenza A viruses or Newcastle disease. We assessed biosecurity measures intended to minimize the risk of influenza virus infection among troops and poultry keepers in military barracks. Go to: Findings We educated troops and used a questionnaire to collect information on animal populations and handling practices from 168 individuals within 203 households in military barracks. Cloacal and tracheal samples were taken from 892 healthy domestic and domesticated wild birds, 91 sick birds and 6 water samples for analysis using molecular techniques for the detection of influenza A virus. Of the 1090 participants educated and 168 that responded to a questionnaire, 818 (75%) and 129 (76.8%) respectively have heard of pandemic avian influenza and the risks associated with its infection. Even though no evidence of the presence of avian influenza infection was found in the 985 birds sampled, only 19.5% of responders indicated they disinfect their coops regularly and 28% wash their hands after handling their birds. Vaccination of birds and use of personal protective clothing while handling the birds were low putting the people at risk. Go to: Conclusion Though some efforts have been made to improve biosecurity practices, interventions that help to protect the poultry flock from direct contact have to be practiced. Basic hygiene like washing of hands with soap and running water and regular cleaning of chicken coops are needed to prevent the spread of diseases among birds and between birds and humans.Item Biosecurity measures to reduce influenza infections in military barracks in Ghana(2015-01-23) Agbenohevi, P.G.; Odoom, J.K.; Bel-Nono, S.; Nyarko, E.O.; Alhassan, M.; Rodgers, D.; Danso, F.; Suu-Ire, R.D.; Bonney, J.H.K.; Aboagye, J.; Kronmann, K.C.; Duplessis, C.; Oyofo, B.A.; Ampofo, W.K.Abstract Background Military barracks in Ghana have backyard poultry populations but the methods used here involve low biosecurity measures and high risk zoonosis such as avian influenza A viruses or Newcastle disease.

This study sought to determine the presence of HDV in HIV/HBV co-infected patients in Ghana. Methods This was a longitudinal purposive study which enrolled 113 HIV/HBV co-infected patients attending clinic at Korle-Bu Teaching Hospital (KBTH) in Accra, Ghana. After consenting, 5 mL whole blood was collected at two-time points (baseline and 4–6 months afterwards). The sera obtained were tested to confirm the presence of HIV, HBV antibodies and/or antigens, and HBV DNA. Antibodies and viral RNA were also determined for HDV. Amplified HBV DNA and HDV RNA were sequenced and phylogenetic analysis carried out with reference sequences from the GenBank to establish the genotypes. Results Of the 113 samples tested 63 (55.7%) were females and 50 (44.25%) were males with a median age of 45 years. A total of 100 (88.5%) samples had detectable HBV surface antigen (HBsAg), and 32 out of the 113 had detectable HBV DNA. Nucleotide sequences were obtained for 15 and 2 samples of HBV and HDV, respectively. Phylogenetic analysis was predominantly genotype E for the HBVs and genotype 1 for the HDVs. Of the 13 samples that were HBsAg unreactive, 4 (30.8%) had detectable HBV DNA suggesting the incidence of occult HBV infections. The percentage occurrence of HDV in this study was observed to be 3.54. Conclusion Our data suggest the presence and circulation of HDV and incidence of occult HBV infection in HIV/HBV co-infected patients in Ghana. This informs health staff and makes it imperative to look out for the presence of HDV and occult HBV in HIV/HBV co-infected patients presenting with potential risk of liver cancers and HBV transmission through haemodialysis and blood transfusions.Item Data management during COVID-19 outbreak response in Ghana: a reference labor atory perspective on key issues and measures(Ghana Med J, 2021) Obodai, E.; Kyei, G.B.; Aboagye, J.; Bonney, E.Y.; Asante, I.A.; Bonney, J.K.H.; Adusei-Poku, M.; Lamptey, H.; Adu, B.; Kenu, E.; Koram, K.A.; Ampofo, W.K.; Odoom, J.K.The COVID-19 pandemic caused by SARS-CoV-2 is an important subject for global health. Ghana experienced low moderate transmission of the disease when the first case was detected in March 12, 2020 until the middle of July when the number of cases begun to drop. By August 24, 2020, the country's total number of confirmed cases stood at 43,622, with 263 deaths. By the same time, the Noguchi Memorial Institute for Medical Research (NMIMR) of the University of Ghana, the primary testing centre for COVID-19, had tested 285,501 with 28,878 confirmed cases. Due to database gaps, there were initial challenges with timely reporting and feedback to stakeholders during the peak surveillance period. The gaps resulted from mismatches between samples and their accompanying case investigation forms, sam ples without case investigation forms and vice versa, huge data entry requirements, and delayed test results. However, a revamp in data management procedures, and systems helped to improve the turnaround time for reporting results to all interested parties and partners. Additionally, inconsistencies such as multiple entries and discrepant patient-sample information were resolved by introducing a barcoding electronic capture system. Here, we describe the main chal lenges with COVID-19 data management and analysis in the laboratory and recommend measures for improvement.Item Occurrence of influenza and bacterial infections in cancer patients receiving radiotherapy in Ghana(Public Library of Science, 2022-07) Arjarquah, A.K.; Obodai, E.; Anie, H.A.; Osei, M.A.; Odoom, J.K.; Bonney, J.H.K.; Behene, E.; Kotey, E.N.; Aboagye, J.; Nyarko, S.O.; Bentum, J.; Yeboah, C.Background Influenza co-infection with bacteria is a leading cause of influenza-related deaths and severe respiratory infections, especially among high-risk groups like cancer patients undergoing treatment. However, acute respiratory infection (ARI)-like symptoms developed by uppertorso cancer (UTC) patients receiving radiotherapy are considered as side-effects of the radiation. Hence influenza and bacterial pathogens implicated in ARI are not investigated. Methods: This prospective cohort study examined 85 in-patients with upper-torso cancers undergoing radiotherapy at the National Radiotherapy, Oncology and Nuclear Medicine Centre (NRONMC) of Korle-Bu Teaching Hospital (KBTH) in Accra, Ghana. Eligible patients who consented were recruited into the study from September 2018 to April 2019. Influenza viruses A and B in addition to the following bacteria species Streptococcus pneumonia, Haemophilus influenzae, Neisseria meningitidis and Staphylococcus aureus were detected from oropharyngeal and nasopharyngeal swab specimens collected at three different time points. Presence of respiratory pathogens were investigated by influenza virus isolation in cell culture, bacterial culture, polymerase chain reaction (PCR) and next generation sequencing (NGS) assays. Results: Of the 85 eligible participants enrolled into the study, 87% were females. Participants were 17 to 77 years old, with a median age of 49 years. Most of the participants (88%) enrolled had at least one pathogen present. The most prevalent pathogen was N. meningitidis (63.4%), followed by H. influenzae (48.8%), Influenza viruses A and B (32.9%), S. pneumoniae (32.9%) and S. aureus (12.2%). Approximately, 65% of these participants developed ARI-like symptoms. Participants with previous episodes of ARI, did not live alone, HNC and total radiation less than 50 Gy were significantly associated with ARI. All treatment forms were also significantly associated with ARI. Conclusion: Data generated from the study suggests that ARI-like symptoms observed among UTC patients receiving radiotherapy in Ghana, could be due to influenza and bacterial single and co-infections in addition to risk factors and not solely the side-effects of radiation as perceived. These findings will be prime importance for diagnosis, prevention, treatment and control for cancer patients who present with such episodes during treatment.Item SARS-CoV-2 detection among international air travellers to Ghana during mandatory quarantine(Ghana Med J, 2021) Adu, B.; Bonney, J.K.H.; Odoom, J.K.; Bonney, E.Y.A.; Obodai, E.; Asante, I.A.; Aboagye, J.; Adusei-Poku, M.A.; Lartey, L.; Asiedu, E.K.; Ampofo, W.K.; Kyei, G.B.Objectives: To determine the prevalence of SARS-CoV-2 detection among international travellers to Ghana during mandatory quarantine. Design: A retrospective cross-sectional study. Setting: Air travellers to Ghana on 21st and 22nd March 2020. Participants: On 21st and 22nd March 2020, a total of 1,030 returning international travellers were mandatorily quar antined in 15 different hotels in Accra and tested for SARS-CoV-2. All of these persons were included in the study. Main outcome measure: Positivity for SARS-CoV-2 by polymerase chain reaction. Results: The initial testing at the beginning of quarantine found 79 (7.7%) individuals to be positive for SARS-CoV 2. In the exit screening after 12 to 13 days of quarantine, it was discovered that 26 of those who tested negative for SARS-CoV-2 in the initial screening subsequently tested positive. Conclusions: Ghana likely averted an early community spread of COVID-19 through the proactive approach to quarantine international travellers during the early phase of the pandemicItem Troop education and avian influenza surveillance in military barracks in Ghana, 2011(2012-11-08) Odoom, J.K.; Bel-Nono, S.; Rodgers, D.; Agbenohevi, P.G.; Dafeamekpor, C.K.; Sowa, R.M.L.; Danso, F.; Tettey, R.; Suu-Ire, R.; Bonney, J.H.K.; Asante, I.A.; Aboagye, J.; Abana, C.Z.Y.; Frimpong, J.A.; Kronmann, K.C.; Oyofo, B.A.; Ampofo, W.K.Abstract Background Influenza A viruses that cause highly pathogenic avian influenza (HPAI) also infect humans. In many developing countries such as Ghana, poultry and humans live in close proximity in both the general and military populations, increasing risk for the spread of HPAI from birds to humans. Respiratory infections such as influenza are especially prone to rapid spread among military populations living in close quarters such as barracks making this a key population for targeted avian influenza surveillance and public health education. Method Twelve military barracks situated in the coastal, tropical rain forest and northern savannah belts of the country were visited and the troops and their families educated on pandemic avian influenza. Attendants at each site was obtained from the attendance sheet provided for registration. The seminars focused on zoonotic diseases, influenza surveillance, pathogenesis of avian influenza, prevention of emerging infections and biosecurity. To help direct public health policies, a questionnaire was used to collect information on animal populations and handling practices from 102 households in the military barracks. Cloacal and tracheal samples were taken from 680 domestic and domesticated wild birds and analysed for influenza A using molecular methods for virus detection. Results Of the 1028 participants that took part in the seminars, 668 (65%) showed good knowledge of pandemic avian influenza and the risks associated with its infection. Even though no evidence of the presence of avian influenza (AI) infection was found in the 680 domestic and wild birds sampled, biosecurity in the households surveyed was very poor. Conclusion Active surveillance revealed that there was no AI circulation in the military barracks in April 2011. Though participants demonstrated good knowledge of pandemic avian influenza, biosecurity practices were minimal. Sustained educational programs are needed to further strengthen avian influenza surveillance and prevention in military barracks.Item Virological surveillance of influenza-like illness among children in Ghana, 2008-2010(Journal of Infectious Diseases, 2012-12) Bonney, J.H.K.; Kronmann, K.C.; Lindan, C.P.; Asante, I.A.; Parbie, P.; Aboagye, J.; Amankwah, J.; Odoom, J.K.; Adjabeng, M.; Nzussouo, N.T.; Ahadzie, L.; Barthel, R.V.; Cornelius, C.; Amofah, G.; Oyofo, B.; Ampofo, W.K.Background The global annual attack rate for influenza is estimated to be 10%-20% in children, although limited information exists for Africa. In 2007, Ghana initiated influenza surveillance by routine monitoring of acute respiratory illness to obtain data on circulating strains. We describe influenza surveillance in children <11 years old who had influenza-like illness (ILI) from January 2008 to December 2010.Methods Oropharyngeal swabs from pediatric outpatients with ILI attending any of 22 health facilities across the country were submitted. We tested swabs for influenza virus using molecular assays, virus isolation, and hemagglutination assays.Results Of the 2810 swabs, 636 (23%) were positive for influenza virus. The percentage of positives by gender was similar. The proportion of ILI cases positive for influenza increased with age from 11% (31/275) in infants (aged 0-1 years) to 31% (377/1219) among children aged 5-10 years (P <. 001). The majority of cases were influenza A (90%), of which 60% were influenza A(H1N1)pdm09. In all 3 years, influenza activity appeared slightly higher during May through July.Conclusions During the 3 years of influenza surveillance in Ghana, children aged <11 years bore a high burden of influenza-associated ILI. © 2012 The Author.
