Epidemiology of influenza in Nigeria: A secondary analysis of the sentinel surveillance data in Nigeria from 2010 - 2020.

BACKGROUND: Influenza is a leading cause of morbidity and mortality globally. Little is known of the true burden and epidemiology of influenza in Africa. Nigeria has a sentinel surveillance system for influenza virus (IFV). This study seeks to describe the epidemiological characteristics of influenza cases in Nigeria through secondary data analysis of the sentinel surveillance data from 2010 to 2020. METHODOLOGY: A retrospective secondary data analysis of data collected from patients with influenza-like illness (ILI) and severe acute respiratory infection (SARI) in the four Nigeria Influenza Sentinel Surveillance sites from January 2010 to December 2020. Data was cleaned and analyzed using Microsoft Excel and Epi info 7.2 for frequencies and proportions. The results of the analysis were summarized in tables and charts. RESULTS: A total of 13,828 suspected cases of influenza were recorded at the sentinel sites during the study period. About 10.3% (1421/13,828) of these tested positive for IFV of which 1243 (87.5%) were ILI patients, 175 (12.3%) SARI patients, and 3 (0.2%) novel H1N1 patients. Males accounted for 54.2% (770/1421) of the confirmed cases. The median age of confirmed cases was 3 years (range: <1month-97 years). Children 0-4 years accounted for 69.3% (985/1421) of all cases. The predominant subtypes were B lineage not determined (32.3%), A/H1N1 pdm09 (28.8%) and A/H3 (23.0%). There were periods of sustained transmission in most years with 2011 having the highest number of cases. Overall, there were more cases around January to March and August to November. Heart disease and chronic shortness of breath were the most common co-morbidities identified among confirmed cases. CONCLUSION: Influenza remains a significant cause of respiratory illness, especially among children aged less than 4 years. Influenza cases occur all year round with irregular seasonality in Nigeria. Children less than 4 years and those with co-morbidities should be prioritized for vaccination. Vaccine composition in the country should take cognizance of the prevailing strains which are type B (lineage not determined), A/H1N1 pdm09 and A/H3.

Clinical presentation and hospitalisation duration of 201 coronavirus disease 2019 patients in Abuja, Nigeria.

BACKGROUND: Knowledge of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is unfolding. Insights from patient features in different environments are therefore vital to understanding the disease and improving outcomes. AIM: This study aimed to describe patient characteristics associated with symptomatic presentation and duration of hospitalisation in coronavirus disease 2019 (COVID-19) patients managed in Abuja. SETTING: The study was conducted in Abuja, the Federal Capital Territory, Nigeria. METHODS: This was a retrospective study of 201 COVID-19 patients hospitalised in the Asokoro District Hospital COVID-19 Isolation and Treatment Centre between April 2020 and July 2020. Demographic and clinical data were obtained and outcomes assessed were symptom presentation and duration of hospitalisation. RESULTS: Patients' median age was 39.3 years (interquartile range [IQR]: 26-52); 65.7% were male and 33.8% were health workers. Up to 49.2% of the patients were overweight or obese, 68.2% had mild COVID-19 at presentation and the most common symptoms were cough (38.3%) and fever (33.8%). Hypertension (22.9%) and diabetes mellitus (7.5%) were the most common comorbidities. The median duration of hospitalisation was 14.4 days (IQR: 9.5-19). Individuals with secondary and tertiary education had higher percentage symptoms presentation (8.5% and 34%, respectively), whilst a history of daily alcohol intake increased the length of hospital stay by 129.0%. CONCLUSION: Higher educational levels were linked with symptom presentation in COVID-19 patients and that daily alcohol intake was significantly associated with longer hospital stay. These findings highlight the importance of public education on COVID-19 for symptom recognition, early presentation and improved outcomes.

Patterns of dyslipidemia amongst hypertensive patients in Abuja, North Central Nigeria.

INTRODUCTION: dyslipidemia and hypertension are independent cardiovascular risk factors that are linked by insulin resistance and commonly coexist as components of the metabolic syndrome. The consequences of dyslipidaemic patterns includes high cardiovascular risk profile and sequalae. Data on lipid patterns amongst hypertensive patients in Abuja, a city with affluent pattern of life style and rising cardiovascular risk profile is very scanty or limited to just levels of total plasma cholesterol. This study was aimed at determining the pattern and frequencies of dyslipidaemic forms among hypertensive patients in Abuja. METHODS: this was a retrospective cohort study with the following data collected; socio-demographics, anthropometric measures and certain metabolic parameters from the new and old groups and analyzed using IBM SPSS Statistics, version 23. All decisions were made using the assymp. Two-sided Pearson χ2 probability. Quantitative variables were expressed as means and standard deviations. Qualitative variables were expressed as percentages. A p-value of ≤0.05 was set as significant. RESULTS: eight hundred and fifty eight (858) cases were enrolled for this study, 704 (82.1%) olds and 154 (17.9%) news. There were 251 (29.3%) males and 607 (70.7%) females. The means of the two groups were largely comparable. The commonest dyslipidaemic type was reduced High density lipoprotein, HDL (96.1%), followed by elevated low-density lipoprotein, LDL (78.6%), then, elevated total cholesterol, (62.3%) TCHOL and elevated triglycerides, TG 43.5%. CONCLUSION: dyslipidemic forms are very common among hypertensive patients in Abuja, Nigeria, particularly reduced HDL. Some observed associations include; middle age, female gender, middle/upper socio-economic classes, low levels of physical activity, overweight/obesity, dysglycaemia and long-standing hypertension.

Coronavirus disease (COVID-19) and acute nonicteric hepatitis: A case report from Asokoro, Nigeria.

We report our first case of Coronavirus disease (COVID-19) infection with hepatitis B co-infection who presented with fever, catarrh, headaches, fatigue, and loss of smell. He had a history of chronic hepatitis B infection which appeared to be inactive given a history of normal outpatient liver tests prior to admission for COVID-19. Following the positive nasopharyngeal polymerase chain reaction diagnosis with COVID-19, liver function tests revealed evidence of hepatitis with elevated bilirubin and liver enzymes and deranged full blood count findings.
