INVESTIGATE THE EFFECTIVENESS OF VECTORS CONTROL PROGRAM  ( A CASE STUDY OF SOME SELECTED PRIMARY SCHOOLS IN DARAZO LGA, BAUCHI STATE.

CHAPTER ONE

INTRODUCTION

Background of the study

The prevalence of vector-borne illnesses continues to pose a substantial public health concern, especially in less developed nations. Transmission of various life-threatening illnesses, including malaria, dengue, Zika, and Chagas disease, is attributed to vectors such as mosquitoes, ticks, and flies (World Health Organisation, 2020). In light of the increasing prevalence of these illnesses, governments and international health organisations have established several vector control initiatives aimed at diminishing or eradicating vector populations and restricting the transmission of these diseases. Globally, vector-borne illnesses constitute more than 17% of all infectious diseases and result in over 700,000 fatalities each year (WHO, 2020). Malaria, for example, has been a persistent problem in sub-Saharan Africa, with more than 200 million cases documented each year globally (Bhatt et al., 2015). The incidence of dengue fever, a disease that mostly impacts tropical and subtropical areas, has been steadily growing, expanding by a factor of 30 throughout the last five decades (Brady et al., 2012). The substantial impact on both human society and the economy caused by chronic illnesses emphasises the need of promptly adopting efficient control strategies. The primary objective of vector control programs is to mitigate the transmission of vector-borne illnesses by specifically targeting the vectors that are responsible for their dissemination. These initiatives often include a range of approaches, such as environmental management, biological control, chemical control, and community education. The primary goals of these programs are two-fold: to decrease the numbers of vectors and to interrupt the contact between vectors and humans that enables the spread of diseases (Wilson et al., 2020). The assessment of the efficacy of vector control programs is crucial in order to guarantee that these interventions successfully accomplish their desired objectives. Typically, the evaluation entails the monitoring and assessment of numerous important indicators, including decreases in vector populations, decreases in disease incidence, and enhancements in the quality of life for impacted communities. Illustratively, the adoption of ITNs has been attributed with a reduction in malaria fatality rates by almost 50% from 2000 to 2015 (WHO, 2021). Nevertheless, the rise of mosquito populations that are resistant to insecticides has raised challenges in maintaining the progress made, requiring ongoing evaluation and adjustment of control methods (Ranson & Lissenden, 2016). Notwithstanding the achievements of vector control programs, there exist various obstacles that restrict their long-term sustainability. A major obstacle is the development of pesticide resistance among vector populations. Notably, there has been a significant rise in pesticide resistance among mosquitoes in certain regions of Africa, which has decreased the effectiveness of both insecticide-resistant mosquitoes (IRS) and insecticide-tolerant mosquitoes (ITNs) (Hemingway et al., 2016). Moreover, vector control initiatives in low-income countries are often hindered by insufficient financial resources, a shortage of skilled staff, and inadequate infrastructure (Yakob & Walker, 2016). Therefore, the researcher sought to investigate the effectiveness of vectors control program  ( a case study of some selected primary schools in Darazo LGA, Bauchi State.

1.2 Statement of the problem

Despite deliberate attempts to manage vectors and prevent illnesses transmitted by vectors in different areas, the effectiveness of these programs typically depends on contextual elements, allocation of resources, and methods of execution. The success of vector control programs depends on several key elements, such as the use of suitable techniques, active involvement of the community, sustainable management strategies, and consistent monitoring and assessment (Ayi et al, 2010). A comprehensive evaluation of the efficacy of the current vector control strategies used in Darazo Local Government Area, Bauchi State, including mosquito nets, pesticide spraying, environmental cleanliness, and health education programs, is necessary. This assessment will provide insight into the degree to which these strategies reduce parasitic illnesses transmitted by vectors. Effective implementation of vector control programs is greatly dependent on active involvement and awareness within the community (Brooker et al, 2018). Hence, it is essential to assess the extent of community engagement, awareness, and compliance with established vector control measures among students, staff, and neighbours in the neighbourhood of Central Primary School. Strategic distribution of resources, including financial, human, and infrastructural resources, is crucial for maintaining vector control initiatives. Hence, the study investigate the effectiveness of vectors control program  ( a case study of some selected primary schools in Darazo LGA, Bauchi State.
