A CRITICAL LOOK ON THE PREVALENCE OF LASSA FEVER IN ESAN WEST LOCAL GOVERNMENT AREA OF EDO STATE
ABSTRACT
Lassa fever is an acute viral haemorrhagic illness caused by Lassa virus, a member of the arenavirus family of viruses. It is transmitted to humans from contacts with food or household items contaminated with rodent excreta. The study was carried out to examine the Prevalence of Lassa Fever in Esan West Local Government Area of Edo State using Ekpoma as a case study. In achieving this aim, the following specific objectives were laid out to find out if there is a poor Lassa fever infection control among health facilities and identify the therapeutic effect of Lassa fever outbreak in Esan West Local Government Area of Edo State. The research design used in this report is descriptive design, utilizing questionnaire method to obtain information from the respondents for this project. A total of 100 (one hundred) respondents were selected for this study to represent the entire population of the study. For null hypotheses were formulated and tested using the one-way ANOVA and the t-test statistical tools at zero point zero five (0.05) level of significance. Primary data were collected from the primary source which questionnaire was used as an instrument of data collection while secondary data were sources from textbooks, journals, newspapers and the internet were employed. The data were presented on a frequency distribution table and analyzed using simple percentage, while hypothesis was tested using chi-square test. This study will be of immense benefit to other researchers who intend to know more on this study and can also be used by non-researchers to build more on their research work. This study contributes to knowledge and could serve as a guide for other study. Based on the findings, it is recommended that public awareness and resilience strategies and mitigation measures in attaining national should be taken. Also, further research should be done on Lassa virus and it natural reservoir in northern, eastern, southern and central African countries.
CHAPTER ONE
1.1 Introduction
Lassa fever is an acute viral haemorrhagic illness caused by Lassa virus, a member of the arenavirus family of viruses (VHFC, 2013). It is transmitted to humans from contacts with food or household items contaminated with rodent excreta (CDC, 2004). The disease is endemic in the rodent population in parts of West Africa. Person-to- person infections and laboratory transmission can also occur, particularly in the hospital environment in the absence of adequate infection control measures (Ogbu et al. 2007). Diagnosis and prompt treatment are essential. Early treatment of Lassa fever is very important for survival and requires specialized treatment using the guanosine analogue ribavirin. Care must also be taken to avoid spread of the disease in hospital settings (Achinge et al., 2013 and Micheal et al., 2001).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Research hypothesis and questions, Limitations of the Study and Definition of technical terms.
1.2 Background of Study
Lassa fever is a highly prevalent viral zoonosis that affects two to three million people in West Africa. This is a rodent- borne disease, which has serious consequences on the population and hospital staff in endemic areas. Lassa fever which has incubation period of 6-21 days is endemic to some parts of Nigeria including Benue state (Coker et al., 2000). Lassa Virus is highly contagious, classified by the American centers for Disease control and prevention as class A virus and requiring bio-safety level for management (Quick Reference Guide, 2015). The disease is especially severe in late pregnancy, with maternal death and/or fetal loss occurring in greater than 80% of cases during the third trimester. There has been concerted effort at prevention of Lassa Fever (LF) outbreak following the unprecedented record of 2012, many events like recent flooding and ethnic clashes among the people have caused an increase in vulnerable population as well as the possibility of human contact with rodents, among which is the Mastomys natalensis, the reservoir and host to the Lassa germ (Weekly Epidemiology Report, 2015).
As reported by WHO, 2005 Lassa hemorrhagic fever caused by the Lassa virus is endemic in some countries in West Africa including Guinea, Liberia, Sierra Leone and parts of Nigeria. It is an acute, highly infectious zoonotic disease whose public health importance is heightened by its nosocomial spread especially in areas endemicity (Fisher-Hoch et al., 2009). The host agent for the Lassa virus is the multimamate rat called mastomys natalensis. Lassa infested rat does not become ill, but sheds the virus in its urine and droppings. Humans are infected when they come in direct contact with this urine, feces deposited on surfaces such as floors or beds, or in food or water (WHO, 2005). Those who eat rodents as delicacies or those who kill them for sport are most likely to be infected by direct contact with its blood. Rat bites on humans is also another avenue for zoonotic transmission.
In the study by Richmond and Baglole (2003) Person-to-person and laboratory infections occur, especially in the hospital environment, by direct contact with blood (including inoculation with contaminated needles), pharyngeal (throat) secretions or urine of a patient, or by sexual contact. Person-to-person spread may occur during the acute phase of fever through aerosolized cough/saliva droplets when the virus is present in the throat. Lassa fever symptomatically mimics that of malaria and typhoid fever and is often not diagnosed in the early stages. The case presents with fever, headache, sore throat, retrostenal pain, nausea, vomiting, diarrhoea, cough, abdominal pain, non-injury related haemorrhage Kerne et al. (2009). In about 80% of the infections, clinical presentation may be mild without any observable symptoms (CDC, 2004) while the remaining 20% may have severe multisystem disease. In the absence of treatment with antiviral drug Ribavirin 15% of patients who get hospitalized will eventually die.
Therefore, in Edo State where the research was carried out, the activities that was conducted is to examine the Prevalence of Lassa Fever in Esan West Local Government Area.
1.3 Statement of Problems
Investigation reveals that lassa fever incubation period varies from six (6) days to twenty one (21) days. It is symptomatic and usually characterized by fever, myalgia, nausea, vomiting, sore throat, abdominal chest pains. Illness may progress to more severe symptoms including haemorrhaging, neurological problems, hearing loss, tremors and encephalitis (CDC, 2014).
Due to the absence of vaccine against the virus and the impractical control of the rodent host (mastomys species) population, control measures are limited to keeping rodents out of homes and food supplies and also maintaining proper personal hygiene. Using these rodents as food source should be discouraged (Ogbu et al., 2007 and Adewuyi et al., 2009).
1.4 Aim and Objectives of Study

This study appraises the post-privatization performance of some privatized enterprises in Nigeria. The specific indicators examined are profitability, productive efficiency, employment, capital investment, and output. The study measures the change in any given indicator of performance by comparing its average value some years before and some years after privatization. Pearson’s rank correlation was deployed to assess the relationship and level of technical efficiency in the selected enterprises. The results show significant increases in these indicators. Privatization is also associated with increase in technical …
