Introduction Success in curtailing the pandemic coronavirus disease (COVID-19) depends largely on a sound understanding of the epidemiologic and clinical profile of cases in a population as well as the case management approach. This study documents the presenting characteristics, treatment modalities and outcomes of the first 32 COVID-19 patients in Nigeria. Methods This retrospective study used medical records of the first 32 patients admitted and discharged from the Mainland Hospital, Lagos State, southwest Nigeria between February 27 and April 6, 2020. The outcomes of interest were death, promptness of admission process and duration of hospitalization. Results The mean age of the patients was 38.1 years (SD: 15.5) and 66% were male. Three-quarters (75%) of the patients presented in moderately severe condition while 16% were asymptomatic. The most common presenting symptoms were fever (59%) and dry cough (44%). The mean time between a positive test result and admission was 1.63 days (SD: 1.31). Almost all (97%) the patients were treated with lopinavir-ritonavir with no recorded death. The median duration of hospital stay was 12 days (IQR: 9-13.5). Conclusion In this preliminary analysis of the first COVID-19 cases in Nigeria, clinical presentation was mild to moderate with no mortality. Processes to improve promptness of admission and reduce hospital stay are required to enhance the response to COVID-19 in Nigeria.
BackgroundWith reports of surges in COVID-19 case numbers across over 50 countries, country-level epidemiological analysis is required to inform context-appropriate response strategies for containment and mitigation of the outbreak. We aimed to compare the epidemiological features of the first and second waves of COVID-19 in Nigeria.MethodsWe conducted a retrospective analysis of the Surveillance Outbreak Response Management and Analysis System data of the first and second epidemiological waves, which were between 27 February and 24 October 2020, and 25 October 2020 to 3 April 2021, respectively. Descriptive statistical measures including frequencies and percentages, test positivity rate (TPR), cumulative incidence (CI) and case fatality rates (CFRs) were compared. A p value of <0.05 was considered statistically significant. All statistical analyses were carried out in STATA V.13.ResultsThere were 802 143 tests recorded during the study period (362 550 and 439 593 in the first and second waves, respectively). Of these, 66 121 (18.2%) and 91 644 (20.8%) tested positive in the first and second waves, respectively. There was a 21.3% increase in the number of tests conducted in the second wave with TPR increasing by 14.3%. CI during the first and second waves were 30.3/100 000 and 42.0/100 000 respectively. During the second wave, confirmed COVID-19 cases increased among females and people 30 years old or younger and decreased among urban residents and individuals with travel history within 14 days of sample collection (p value <0.001). Most confirmed cases were asymptomatic at diagnosis during both waves: 74.9% in the first wave; 79.7% in the second wave. CFR decreased during the second wave (0.7%) compared with the first wave (1.8%).ConclusionNigeria experienced a larger but less severe second wave of COVID-19. Continued implementation of public health and social measures is needed to mitigate the resurgence of another wave.
Background:The evaluation of degree of ventricular enlargement should be based on established indices rather than on personal experience as this is highly subjective. Our aim was to establish normal values for Evans index in a Nigerian adult population as none has been found in the Nigerian medical literature.Materials and Methods:Axial computerized tomographic brain scans of 488 normal subjects were reviewed retrospectively. Of them, 319 (65.36%) of the patients were males and 169 (34.63%) were females; their ages ranged from 18 to 84 years with a mean age of 37.26 years. The images were acquired using a multi-slice GE Sigma excite scanner. Evans index was measured as the linear ratio of the total width of the frontal horns of the cerebral lateral ventricles to the maximum intracranial diameter.Results:The mean value for Evans index for the studied population was 0.252 ± 0.04. The EI increased with age and it was slightly higher among males. The difference in Evans value in males and females was not statistically significant. Individuals above 60 years old had the highest Evans values in both sexes.Conclusion:This study has established ranges of normal value for Evans index in a Nigerian population. It agrees with the diagnostic cut-off value of > 0.3 for hydrocephalus and it compares well with that of the Caucasians.
Introduction The COVID-19 pandemic has had a great toll on global health. Frontline healthcare workers (FHCW) directly involved in the treatment of COVID-19 patients have faced some physical and psychological challenges. This study explored the stigma and traumatic experiences of the FHCW during the COVID-19 pandemic in Nigeria. Methods We recruited twenty FHCW directly involved in the treatment of COVID-19 patients through purposive and snowball sampling techniques. Face-to-face in-depth interviews were conducted for all participants, and qualitative analysis of data was done using Colaizzi’s phenomenological method. Results Five themes identified were: Early stage of the pandemic (fear, anxiety, public fright, other countries repatriating their citizens, the socio-economic impact of the pandemic and a call to duty for the FHCW); working with COVID-19 patients (excitement on patients recovery and duty stress); psychological, mental and emotional trauma; stigmatization (stigmatized by colleagues, family, friends or their residential communities, reasons for stigmatization which were fear of infection, limited knowledge of the virus and working at the isolation centre and the effect of stigma); and recommendations (education and awareness creation, government showing more care towards the FHCW and provision of health insurance for FHCW to take care of those that get infected in the line of duty). Conclusion Stigmatization has proven to be a major challenge for FHCW in conducting their duties. The psychological impact experienced by FHCW may affect the quality of the services rendered by these workers. The study reveals the need of education and awareness creation in the ongoing pandemic. There is a need for the government and society to acknowledge and appreciate the efforts of FHCW.
Background COVID-19 pandemic has resulted in global health and economic crisis. We investigated the experiences of frontline health care workers recovering from COVID-19 in Lagos State Nigeria. Methods We conducted a qualitative study among frontline health workers recovering from COVID-19 in Lagos State, Nigeria. We interviewed 12 respondents based on data saturation. We used a checklist of questions to guide the interview according to the phenomenon under study. Data obtained was analyzed using Colaizzi's phenomenological method. Results The study was summarized under five themes: knowledge of COVID-19, exposure, reactions, challenges and recommendations. The respondents were quite knowledgeable on COVID-19, their reactions when informed of their status were denial, anxiety, distress, disorientation, crying for fear of stigmatization, while some were psychologically prepared. Reactions from colleagues, family and friends were encouraging and provided solace for them with a few colleagues and families that had negative reactions. Challenges include anosmia, movement restriction, loneliness, worries about the state of their families, nondisclosure of status to family members, non-conducive isolation centre with limited space, insomnia, stigmatization by health workers at the isolation centre, extended duration of stay, delay in the release of test results and use of ambulance for evacuation to the isolation centres. Coping strategies were watching movies, phone calls, use of social media, listening to music, attending webinars, working on projects and reading spiritual books. Recommendations were early laboratory testing of samples and conveying of results, increase testing capacity, the need of health care workers to be more compassionate, better method of evacuation of people that tested positive to COVID-19, aside the use of ambulance that increases the likelihood of stigmatization and standard guideline for the case management of people recovering from COVID-19 in Lagos state. Conclusions Respondents felt stigmatized and psychologically and morally traumatized. Isolation is a difficult experience and some negative emotions as expressed by previous studies were experienced by the respondents. There is need for increased testing capacity, timely results, early evacuation and creation of more isolation centres in Lagos State due to the rising number of cases and shortage of bed space.
Background: The Nigeria Centre for Disease Control (NCDC) has categorized dengue fever as a priority epidemic-prone disease. Kano metropolis is a hub for international trade and has seen rapid population growth with unplanned urbanisation. This provides the right environment for dengue virus transmission and spread. Most fevers in Nigeria and Kano in particular are treated as malaria or typhoid. This study aimed to determine the prevalence and factors associated with dengue fever and dengue-malaria co-infection among febrile patients in Kano metropolis. Methodology: We conducted a hospital-based cross-sectional study among febrile patients attending secondary health facilities in Kano metropolis. We used multistage sampling technique to recruit 440 participants into the study. An interviewer administered structured questionnaire was used to collect participants’ information, while blood was screened for malaria using rapid diagnostic test (RDT) kit and tested for dengue fever using an ELISA kit for dengue IgM. Data was cleaned and analysed using Microsoft Excel 2016 and Epi Info version 7.2 to calculate frequencies, proportions and odds ratios. Results: The median age of participants was 24 years (IQR= 13-36 years) while the age-group most represented was the 10-19 years’ age group with 97 (22.9%) participants. Males constituted 257 (60.6%) while most were single 238 (56.1%). Dengue IgM was positive for 332 (78.3%), while malaria RDT was positive for 81 (19.1%) and 67 (15.8%) were positive for both. Those aged above 25 years were less likely to present with dengue fever (OR=0.6; 95% CI=0.33-0.97). Dengue fever contributes a high percentage to febrile illnesses seen in Kano metropolis. Significant proportions of febrile patients have both dengue and malaria co-infection. None of the participants had dengue as a presumptive diagnosis. Conclusion: These findings imply dengue fever should feature as a prominent differential for febrile illnesses and dengue screening tests should be made available for all cases seen in Kano.

La métropole de Kano est une plaque tournante du commerce international et a connu une croissance démographique rapide avec une urbanisation imprévue. Cela fournit le bon environnement pour la transmission et la propagation du virus de la dengue. La plupart des fièvres au Nigeria et à Kano en particulier sont traitées comme le paludisme ou la typhoïde. Cette étude visait à déterminer la prévalence et les facteurs associés à la dengue et à la co-infection dengue-paludisme chez les patients fébriles de la métropole de Kano. Méthodologie: Nous avons mené une étude transversale en milieu hospitalier auprès de patients fébriles fréquentant des établissements de santé secondaires de la métropole de Kano. Nous avons utilisé une technique d'échantillonnage en plusieurs étapes pour recruter 440 participants dans l'étude. Un questionnaire structuré administré par un intervieweur a été utilisé pour collecter les informations des participants, tandis que le sang a été testé pour le paludisme à l'aide d'un kit de test de diagnostic rapide (TDR) et testé pour la dengue à l'aide d'un kit ELISA pour les IgM de la dengue. Les données ont été nettoyées et analysées à l'aide de Microsoft Excel 2016 et d'Epi Info version 7.2 pour calculer les fréquences, les proportions et les rapports de cotes. Résultats: L'âge médian des participants était de 24 ans (IQR=13-36 ans) tandis que le groupe d'âge le plus représenté était le groupe d'âge 10-19 ans avec 97 (22,9%) participants. Les hommes en constituaient 257 (60,6%) tandis que la plupart étaient célibataires 238 (56,1%). Les IgM de la dengue étaient positives pour 332 (78,3%), tandis que les TDR du paludisme étaient positifs pour 81 (19,1%) et 67 (15,8%) étaient positifs pour les deux. Les personnes âgées de plus de 25 ans étaient moins susceptibles de présenter une fièvre dengue (OR=0,6; IC à 95%=0,33-0,97). La dengue contribue à un pourcentage élevé des maladies fébriles observées dans la métropole de Kano. Des proportions significatives de patients fébriles présentent une co-infection à la fois par la dengue et le paludisme. Aucun des participants n'avait de dengue comme diagnostic présumé. Conclusion: Ces résultats impliquent que la dengue devrait apparaître comme un différentiel important pour les maladies fébriles et des tests de dépistage de la dengue devraient être disponibles pour tous les cas observés à Kano.

Introduction: Lassa fever (LF) is a communicable viral haemorrhagic disease. Person-to-person spread occurs by inhalation or direct contact with the bodily fluids of an infected patient. Infection Prevention and Control (IPC) is essential in healthcare facilities for the wellbeing and safety of patients, staff and visitors. Federal Teaching Hospital, Abakaliki is the designated treatment center for LF in Ebonyi State. We assessed IPC practices in this facility during the 2018 outbreak of LF involving healthcare workers. Methods: We conducted a cross-sectional study on 135 healthcare workers selected by systematic sampling. Information on their knowledge and practice of IPC was collected using a pre-tested, semi-structured questionnaire. We classified knowledge into "good", "fair" and "poor" based on the total correct response. Those that scored ≥75% of the maximum score were classified as good, 50-74% as fair and <50% as poor. We calculated prevalence odds ratio and 95% confidence intervals of the odds ratio to determine the factors associated with good knowledge scores. We purposively sampled key units involved in the management of suspected Lassa fever cases and assessed the availability of basic IPC requirements. Results: The mean age of the respondents was 37.6 ± 7.6 years and 75 (55.6%) were females. Fifty-seven (42.5%), 29 (21.6%) and 13 (9.9%) respondents claimed always to have gloves, running water and hand washing soaps, respectively, in their units. The proportion of respondents with good knowledge of IPC measures was 71.8%, while 58.5% and 37.8% had good knowledge of LF epidemiology and LF clinical features, respectively. Being a core health worker (OR: 3.39 95%CI: 1.38-8.32) was significantly associated with good knowledge of LF epidemiology. Being male (OR: 1.55 95%CI: 0.72-3.34) and having spent >15years in the facility (OR: 1.16 95%CI: 0.39-3.44) were associated with good knowledge of IPC precautionary measures. However, these associations were not statistically significant. Conclusions: The majority of the staff had good knowledge of IPC. However, knowledge of LF epidemiology was greater among those whose roles were related to management of LF cases. We recommended more awareness on LF, IPC practices and improved supply of IPC commodities.
