Disasters in Nigeria: A Public Health Perspective

Background: Nigeria is the most populous black nation on earth with some fragile demographic, socio-economic and health indices. The country has been having its own share of both natural and man-made disasters. This paper discussed an overview of disasters and some socio-demographic characteristics of Nigeria, factors in vulnerability of disasters, public health impacts and issues in disaster management in Nigeria among others from a public health perspective and the way forward.Methods: The authors undertook full searches (September-November, 2012) of original research, reports and reviews using Medline, pubMed, Embase and World Health Organisation (WHO) database. Search words were disaster, disasters in Nigeria, and public health impacts. Part of the data used was personal communications and in-press publications.Results: The results revealed significant number of disasters in Nigeria, such as plane crashes, oil pipeline fire explosions, collapsed buildings, terrorist attacks, civil strife, and flood, among others. Some of the identified issues that hampered quick response and recovery included poor and ineffective search and rescue operations, poverty, poor public and community education on disaster management, among others.Conclusion: There is need for public and community education on disaster and its management, disaster preparedness, wellcoordinated and effective search and rescue operations, capacity building, tackling corruption and poverty reduction.Keywords: Disaster, Public Health, Public Education, Disaster Mitigation, Nigeri

Climate simulations for the region indicate warmer-than-normal temperatures and wetter conditions for the snow season (November–April) during the twenty-first century. However, despite projected increases in seasonal precipitation, statistically significant negative trends in snow water equivalent (SWE) are found for the region. Snow cover is likely to migrate northward in the future as a result of warmer-than-present air temperatures, with higher loss rates in northern latitudes and at high elevation. Decreases in future (2041–95) snow cover in early spring will likely affect the timing of maximum spring peak streamflow, with earlier peaks predicted in more than 80% of the 124 basins studied

hospital waste management as a potential hazard in selected primary healthcare centres in zaria nigeria

The operations of health facilities generate waste; a common characteristic of hospitals and Primary Healthcare centres. However, improper handling of hospital waste constitutes potential risks to the environment and human health. Unfortunately, hospital waste management is not yet carried out with a satisfactory level of safety in many parts of the globe, especially in the underdeveloped world. This study was carried out with the aim of assessing hospital waste management practices among selected Primary Healthcare Centres (PHCs) in Zaria, Nigeria. A cross sectional descriptive study was carried out between October 2012 and March, 2013 using staff of the PHCs and an interviewer-administered questionnaire, checklist and participant observations. Majority of the staff of the PHCs were nurses (37%) and the knowledge score of all the staff was 5 out of 10 (50%). About 73% had training on hospital waste management 31% had reported injury by sharps. Also, 66% use protective hand gloves while doing their work. Wheel barrow was the commonest method of transporting waste and open burning was the final method of waste disposal by the PHCs. There is a need for safer means of waste disposal among the medical facilities visited. It was, therefore, recommended among others that funds should be made available to the PHCs. This is to ensure the acquisition of all facilities needed in hospital waste management and disposal. There should be training and re-training of health staff on current hospital waste management to meet global best practices. http://dx.doi.org/10.4314/njt.v33i2.1

Functional Memory B Cells and Long-Lived Plasma Cells Are Generated after a Single Plasmodium chabaudi Infection in Mice

Antibodies have long been shown to play a critical role in naturally acquired immunity to malaria, but it has been suggested that Plasmodium-specific antibodies in humans may not be long lived. The cellular mechanisms underlying B cell and antibody responses are difficult to study in human infections; therefore, we have investigated the kinetics, duration and characteristics of the Plasmodium-specific memory B cell response in an infection of P. chabaudi in mice. Memory B cells and plasma cells specific for the C-terminal region of Merozoite Surface Protein 1 were detectable for more than eight months following primary infection. Furthermore, a classical memory response comprised predominantly of the T-cell dependent isotypes IgG2c, IgG2b and IgG1 was elicited upon rechallenge with the homologous parasite, confirming the generation of functional memory B cells. Using cyclophosphamide treatment to discriminate between long-lived and short-lived plasma cells, we demonstrated long-lived cells secreting Plasmodium-specific IgG in both bone marrow and in spleens of infected mice. The presence of these long-lived cells was independent of the presence of chronic infection, as removal of parasites with anti-malarial drugs had no impact on their numbers. Thus, in this model of malaria, both functional Plasmodium-specific memory B cells and long-lived plasma cells can be generated, suggesting that defects in generating these cell populations may not be the reason for generating short-lived antibody responses
