1.1 Introduction
Vector control refers to the systematic application of environmental, biological, and chemical methods to reduce or eliminate disease-transmitting organisms, particularly mosquitoes, in order to prevent the spread of infectious diseases. According to the World Health Organization (2024), vector control is one of the most effective strategies for reducing malaria transmission because it targets the mosquito vectors responsible for spreading the Plasmodium parasite. Public health, on the other hand, is the science and practice of protecting and improving the health of populations through disease prevention, health promotion, policy development, and community-based interventions (Centers for Disease Control and Prevention [CDC], 2023). The integration of vector control within public health programmes has become essential in addressing malaria, which continues to threaten millions of people, especially in sub-Saharan Africa.
Malaria is a mosquito-borne infectious disease caused by Plasmodium parasites and transmitted through the bite of infected female Anopheles mosquitoes. According to the World Health Organization (2024), malaria remains one of the world's most significant public health concerns, with Africa accounting for the overwhelming majority of global malaria cases and deaths. Nigeria bears the highest malaria burden globally, contributing a substantial proportion of worldwide infections and mortality each year. The disease places enormous pressure on households, healthcare facilities, educational systems, and the national economy through increased healthcare costs, reduced productivity, absenteeism from work and school, and preventable loss of lives.
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, limitation of the study and definition of terms.
1.2 Background of Study
Vector control is one of the oldest and most effective public health approaches for preventing mosquito-borne diseases, particularly malaria. According to World Health Organization (2024), vector control involves the application of environmental, biological, and chemical interventions aimed at reducing human contact with disease-carrying mosquitoes and interrupting disease transmission. Public health, according to Centers for Disease Control and Prevention (2023), is concerned with protecting and improving the health of populations through disease prevention, health promotion, and organized community efforts. The integration of vector control into public health programmes has significantly contributed to reducing the incidence of malaria in many countries. However, the sustainability of these interventions depends largely on the level of participation and commitment demonstrated by the communities where they are implemented.
Malaria remains one of the most serious public health concerns across the world, particularly in sub-Saharan Africa. According to World Health Organization (2024), malaria is caused by Plasmodium parasites transmitted through the bites of infected female Anopheles mosquitoes. The organization reported that more than 260 million malaria cases and over 590,000 malaria-related deaths were recorded globally, with Africa accounting for the overwhelming majority of these cases. Nigeria continues to bear the highest malaria burden worldwide because of favourable climatic conditions for mosquito breeding, rapid population growth, inadequate environmental sanitation, and unequal access to healthcare services. The disease continues to affect household income, educational attainment, labour productivity, and national economic development through increased healthcare expenditure and loss of productive working hours.
According to National Malaria Elimination Programme (2021), Nigeria has adopted several malaria control strategies, including the distribution of long-lasting insecticide-treated nets, indoor residual spraying, seasonal malaria chemoprevention, prompt diagnosis and treatment, intermittent preventive treatment for pregnant women, and environmental management. The programme reported that these interventions have improved access to malaria prevention services in many parts of the country. Similarly, World Health Organization (2022) asserted that integrated vector management provides a coordinated framework that combines multiple control strategies based on scientific evidence and local environmental conditions.
Community participation has become an essential component of effective public health interventions because sustainable disease prevention depends on behavioural change at the grassroots level. According to United Nations Children's Fund (2023), community participation involves the active engagement of individuals, households, community leaders, civil society organizations, and local institutions in health-related planning and implementation. The organization reported that when communities actively participate in health programmes, they are more likely to adopt preventive behaviours, maintain healthier environments, and encourage wider acceptance of public health interventions. Active participation also strengthens local ownership, promotes accountability, and improves the long-term sustainability of disease prevention programmes. Furthermore, David H. Peters (2019) asserted that community engagement improves the effectiveness of health systems by encouraging collaboration between healthcare providers and community members. Building on this perspective, Joanne P. Kaufman (2020) contended that meaningful community participation increases trust in health interventions, encourages compliance with preventive guidelines, and promotes shared responsibility for disease control.
According to World Health Organization (2022), vector control activities become more effective when community members participate in eliminating stagnant water, clearing blocked drainage systems, maintaining clean surroundings, disposing of waste properly, and supporting indoor residual spraying campaigns. Likewise, UNICEF (2023) affirmed that households that consistently use insecticide-treated mosquito nets and participate in community sanitation programmes experience lower exposure to mosquito bites than households with poor preventive practices.
Nigeria has witnessed increased collaboration between government institutions and development partners in the fight against malaria. Supporting this position, Malaria No More Nigeria (2023) reported that sustained advocacy, health education, community mobilization, policy engagement, and strategic partnerships have contributed to expanding malaria awareness across different states. The organization continues to support public awareness campaigns, strengthen health communication, mobilize community volunteers, and advocate for increased investment in malaria elimination. These interventions are designed to empower communities to become active participants rather than passive beneficiaries of malaria prevention programmes.
Moreover, according to Roll Back Malaria Partnership (2022), successful malaria elimination depends on coordinated action involving governments, healthcare professionals, private organizations, development partners, researchers, and local communities. The partnership stated that behavioural change communication remains a critical element of malaria control because preventive technologies alone cannot eliminate malaria without consistent community acceptance and utilization. Public awareness campaigns therefore serve as an important bridge between scientific interventions and community action. This study is set against the backdrop of the persistent burden of malaria in Nigeria despite ongoing vector control interventions and increasing investments in public health programmes.
1.3 Statement of Problems
Investigation revealed that malaria remains one of the leading public health challenges in Nigeria, accounting for a significant proportion of illness, hospital visits, and preventable deaths, particularly among children under five years of age and pregnant women. Although governments, international partners, and non-governmental organizations have implemented various malaria control programmes, the burden of the disease remains high in many communities (World Health Organization [WHO], 2024).
Additionally, differences in cultural beliefs, socioeconomic conditions, educational levels, and access to health information influence the willingness of community members to participate in malaria prevention programmes. Without adequate understanding of these factors, interventions may fail to achieve their intended outcomes or produce lasting behavioural change within affected communities (National Malaria Elimination Programme [NMEP] & WHO, 2021).
Furthermore, malaria No More Nigeria has continued to promote advocacy, public awareness campaigns, community mobilization, and partnerships aimed at reducing malaria prevalence across the country. Despite these efforts, there is limited empirical evidence on the extent to which community participation has influenced the effectiveness of vector control initiatives implemented by the organization (Malaria No More Nigeria, 2023). It is against this backdrop that this study seeks to assess the role of community participation in vector control and malaria prevention in Nigeria, with particular reference to Malaria No More Nigeria.
