Emergence and spread of two SARS-CoV-2 variants of interest in Nigeria.

Identifying the dissemination patterns and impacts of a virus of economic or health importance during a pandemic is crucial, as it informs the public on policies for containment in order to reduce the spread of the virus. In this study, we integrated genomic and travel data to investigate the emergence and spread of the SARS-CoV-2 B.1.1.318 and B.1.525 (Eta) variants of interest in Nigeria and the wider Africa region. By integrating travel data and phylogeographic reconstructions, we find that these two variants that arose during the second wave in Nigeria emerged from within Africa, with the B.1.525 from Nigeria, and then spread to other parts of the world. Data from this study show how regional connectivity of Nigeria drove the spread of these variants of interest to surrounding countries and those connected by air-traffic. Our findings demonstrate the power of genomic analysis when combined with mobility and epidemiological data to identify the drivers of transmission, as bidirectional transmission within and between African nations are grossly underestimated as seen in our import risk index estimates

Overweight and obesity profiles in Niger Delta Region, Nigeria

Introduction: Overweight and obesity are global public health problems because of their effect on individuals, families and communities. The objective of this study was to describe the profile of overweight and obesity amongst adult out patients in Uyo in the Niger Delta region of Nigeria. Method: This was a cross-sectional descriptive study done between October 2011 and March 2012. Using a systematic sampling technique, 584 subjects aged 18–65 years were recruited; data were collected with a structured questionnaire. Subjects were measured for height, weight, waist and hip circumferences. Body mass index (BMI) and waist–hip ratio (WHR) were calculated. Subjects with a BMI of 25.0 kg/m2 – 29.9 kg/m2 were regarded as being overweight whilst a BMI of > 30.0 kg/m2 was regarded as obese. Subjects with a WHR of > 0.90 for men or > 0.85 for women were regarded as having abnormal WHR. Results: Of the 584 subjects, 196 (36.6%) were men and 388 (66.4%) women. The mean age for men and women was 43.3 ± 17.8 years and 50.2 ± 13.6 years, respectively. The prevalence of overweight amongst men was 39.8% versus 31.7% for women; obesity in men was 28.0% versus 52.0% in women. Overweight and obesity were more prevalent in subjects aged 25–54 years and amongst married subjects. There was a significant relationship between obesity and television viewing (p = 0.003). Hypertension (p = 0.008) and osteoarthropathies (p = 0.043) were more prevalent amongst the obese than the non-obese subjects. Conclusion: Overweight and obesity are now common in our environment. There is therefore a need for more public education about the health consequences of big body size

Motorcycle Road Traffic Injuries in Southern Nigeria: The Small Motorcycle as a Prevention Strategy

Background: The commonest mode of public transportation in Uyo is by motorcycle. There are two sizes of motorcycle in common use - the big one (Qlink or Skygo model, made in China) and the small one (C90, made in China). The study was carried out to determine if there is a lower risk of RTI severe enough to be brought to the hospital, attributable to using a small motorcycle. Methods: Motorcycle RTI victims admitted at the Accident and Emergency department of the University of Uyo Teaching Hospital (UUTH), were reviewed prospectively over a 15 month period. Three community visual surveys of the proportion of small to large motorcycles were also conducted. Results: A total of 131 RTI victims were reviewed over 15 months. The visual surveys of motorcycles in Uyo revealed that the mean proportion of small to large is 38 to 62, a ratio of 1:1.6. Eighty-three (63.3%) of the 131 RTI′s involved motorcycles. 74 of these occurred in large motorcycles. There was a statistically significant relationship between motorcycle size and occurrence of an RTI severe enough to be brought to hospital. Conclusion: There is a lower risk of RTI severe enough to be brought to hospital, from using a small motorcycle
