Clinical characteristics, predictors of symptomatic coronavirus disease 2019 and duration of hospitalisation in a cohort of 632 Patients in Lagos State, Nigeria.

OBJECTIVE: The clinical spectrum of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is still evolving. This study describes the clinical characteristics and investigates factors that predict symptomatic presentation and duration of hospitalisation in a cohort of coronavirus disease 2019 (COVID-19) patients managed in Lagos, Nigeria. METHODOLOGY: This was a retrospective assessment of patients hospitalised with COVID-19 disease in six dedicated facilities in Lagos, Nigeria, between April 1st and May 31st 2020. Participants were individuals with laboratory-confirmed SARS-CoV-2 infection. The outcome measures were presence of symptoms and duration of hospitalisation. Demographic and comorbidity data were also obtained. Statistical analysis was done using STATA 15.0 software, with P < 0.05 being considered statistically significant. RESULTS: A total of 632 cases were analysed. The median age was 40 years (IQR: 30.5-49); male patients accounted for 60.1%. About 63% of patients were asymptomatic at presentation. Among the symptomatic, the most common symptoms were cough (47.4%) and fever (39.7%). The most common comorbidities were hypertension (16.8%) and diabetes (5.2%). The median duration of hospitalisation was 10 days (IQR: 8-14). Comorbidities increased the odds of presenting with symptoms 1.6-fold (P = 0.025) for one comorbidity and 3.2-fold (P = 0.005) for ≥2 comorbidities. Individuals aged ≥50 years were twice as likely to be hospitalised for more than 14 days compared to individuals aged <50 years (P = 0.016). CONCLUSION: Most individuals had no symptoms with comorbidities increasing the likelihood of symptoms. Older age was associated with longer duration of hospitalisation. Age and comorbidities should be used for COVID-19 triaging for efficient resource allocation.

PATTERN AND OUTCOME OF TETANUS IN A TERTIARY HEALTH FACILITY IN NORTH WEST NIGERIA.

BACKGROUND: Tetanus, a disease that is largely preventable, is still a major public health problem in the developing world and is associated with high morbidity and mortality. There is a paucity of published literature on adult (non-neonatal) tetanus in this study area in Nigeria. METHODS: This was a study describing the clinical characteristics of patients who were clinically diagnosed with tetanus in Ahmadu Bello University Teaching Hospital (ABUTH) Zaria, northwest of Nigeria between January 2001 and December 2014. RESULTS: A total of 91 cases were reviewed. The mean patient age was 20 years, and male to female ratio 2.9:1. The majority (88%) of patients were < 40 years old. The mean onset period was 19 days, nearly all patients (96.7%) had generalized tetanus, and the commonest presenting signs were spasm (93.4%) and trimus (78.0%). The most common site of injury was lower limbs (64.8% of cases). The complication rate was 71.4% and case fatality was 48.4%. CONCLUSION: Tetanus is still a major public health problem in our setting and affects the younger age group with a high case fatality rate. The incidence of tetanus can be reduced drastically by an effective and sustained immunization program.
