Rabies in Developing Countries: Challenges Amid Economic Constraints and Co-Existing Neglected Tropical Diseases

About this Research Topic

Background

The presence of rabies as a neglected tropical disease (NTD) in developing countries highlights the significant challenges posed by economic constraints and the presence of other NTDs. Rabies, a fatal zoonotic viral disease, remains a public health emergency in regions where limited resources, poverty, and co-existing NTDs create barriers to its effective control. These conditions contribute to the disease’s persistence and hinder the implementation of coordinated eradication strategies.

While rabies is endemic to many low- and middle-income countries (LMICs), particularly in Africa and Asia, the lack of adequate public health infrastructure and limited access to post-exposure prophylaxis (PEP) exacerbate its impact. This reality underscores the need for targeted interventions that address the broader socio-economic context of rabies transmission and control.

Economic challenges in developing countries significantly limit healthcare and veterinary services, resulting in poor rabies vaccine coverage and inadequate surveillance systems. These issues are compounded by the burden of NTDs, which compete for already scarce resources. Additionally, the costs associated with rabies prevention, including canine vaccination campaigns and PEP, are often prohibitive in low-income settings, leaving many communities unprotected.

Phylogeographic studies of rabies provide critical insights into the virus's transmission patterns and evolution. By analyzing the genetic diversity and geographic distribution of rabies virus strains, researchers can identify regional reservoirs, track cross-border movements, and predict outbreaks. These studies are particularly valuable in developing countries, where gaps in surveillance data often obscure the true burden of the disease. Integrating phylogeographic analysis into rabies control programs can enhance the targeting of interventions and improve the understanding of how socio-environmental factors shape transmission dynamics.

The World Health Organization (WHO) has been instrumental in addressing NTDs, including rabies, through the “zero dog mediated human rabies by 2030 campaign”. However, economic and infrastructural barriers in developing countries necessitate innovative approaches that maximize the impact of limited resources. Regional collaborations, supported by international funding and expertise, are critical to bridging these gaps.

This Research Topic aims to explore strategies for tackling rabies in LMICs settings, with a focus on the interplay between rabies and other NTDs. We welcome a diverse range of contributions, including opinion pieces, systematic reviews, and original research, covering themes such as:
• Phylogeographic Studies: Investigating the genetic diversity and geographic distribution of rabies virus strains to inform targeted interventions;
• Transmission Dynamics: Studies on how rabies spreads within and between human and animal populations, including the role of intermediate hosts;
• Rapid Diagnostics and Surveillance: Development of cost-effective testing and enhanced surveillance systems for early detection and outbreak prevention;
• Vector and Reservoir Control: Identification of animal reservoirs and sustainable strategies for controlling rabies vectors;
• Drug and Vaccine Development: Advances in rabies vaccines, including affordable formulations and novel delivery methods;
• Mass Vaccination Campaigns: Evaluating the implementation and impact of large-scale dog vaccination programs and their cost-effectiveness;
• Case Management and PEP Accessibility: Advancements in individual care and improving access to post-exposure prophylaxis in low-resource settings;
• One Health Approach: Collaborative efforts that integrate human, animal, and environmental health to address the socio-ecological determinants of rabies;
• Policy Frameworks: The impact of varying regional policies on rabies control efforts, including implications of rabies classification on intervention strategies;
• Community Engagement: Exploring the role of education, local initiatives, and participatory programs in the eradication of rabies and other NTDs.

The control and eventual eradication of rabies in developing countries require a comprehensive approach that considers economic constraints and the broader context of co-existing NTDs. By integrating phylogeographic analyses, community engagement, and targeted public health interventions, stakeholders can overcome the challenges posed by resource limitations and achieve sustainable progress in rabies prevention and control.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.
