RESUMO
The objective of this study was to describe the epidemiology of COVID-19 in Nigeria with a view of generating evidence to enhance planning and response strategies. A national surveillance dataset between 27 February and 6 June 2020 was retrospectively analysed, with confirmatory testing for COVID-19 done by real-time polymerase chain reaction (RT-PCR). The primary outcomes were cumulative incidence (CI) and case fatality (CF). A total of 40 926 persons (67% of total 60 839) had complete records of RT-PCR test across 35 states and the Federal Capital Territory, 12 289 (30.0%) of whom were confirmed COVID-19 cases. Of those confirmed cases, 3467 (28.2%) had complete records of clinical outcome (alive or dead), 342 (9.9%) of which died. The overall CI and CF were 5.6 per 100 000 population and 2.8%, respectively. The highest proportion of COVID-19 cases and deaths were recorded in persons aged 31-40 years (25.5%) and 61-70 years (26.6%), respectively; and males accounted for a higher proportion of confirmed cases (65.8%) and deaths (79.0%). Sixty-six per cent of confirmed COVID-19 cases were asymptomatic at diagnosis. In conclusion, this paper has provided an insight into the early epidemiology of COVID-19 in Nigeria, which could be useful for contextualising public health planning.

This study examines the effect of the whole seed of Garcinia kola [GKS] on various blood parameters, in adult male albino rats. Five groups, of 6 animals per group, were treated by gavage with suspensions of graded concentrations of GKS daily for 5 weeks. The animals were then sacrificed and blood was obtained for estimation of the data herein presented. Packed red cell volume [PCV], hemoglobin concentration [Hb], and red blood cell count [RBC] showed significantly [P<0.05], increased response to treatment with GKS; while the platelet and white blood cell [WBC] counts showed no corresponding increase with increasing GKS dosage. The mean red blood cell volume [MCV] and mean cell hemoglobin [MCH] levels decreased with increasing GKS dosage. Prothrombin time [PT] and activated partial thromboplastin time [APPT] were both prolonged with increased GKS dosage; while the serum lipids (cholesterol and triglycerides) decreased significantly [P<0.05] with increased GKS dosage.
