Short Communication - (2025)Volume 13, Issue 1
Emerging Infectious Diseases (EIDs) remain a persistent threat to global public health, with low-resource settings often bearing a disproportionate burden due to limited healthcare infrastructure and delayed outbreak detection. Community-Based Surveillance (CBS) has emerged as a promising tool to bridge this gap by engaging local populations in early case identification and reporting. While CBS systems have been implemented in various regions, evidence on their long-term effectiveness in outbreak prevention and response is limited and fragmented [1,2].
This short communication evaluates the impact of CBS programs over time in selected low-resource countries, focusing on early detection, response time, and outbreak mitigation. CBS typically relies on non-professional community members such as volunteers, teachers, and local health workers who are trained to identify and report symptoms indicative of epidemic-prone diseases like cholera, Ebola, or dengue. The rationale is that communities are often the first to witness unusual health events, making them key players in initiating a rapid public health response [3,4].
Case studies from Uganda, Sierra Leone, and Nepal illustrate the varying success of CBS systems. In Uganda, CBS contributed significantly to the early detection of Ebola virus disease during the 2019 outbreak. The average reporting time was reduced by 48% compared to previous outbreaks without CBS integration. In Sierra Leone, CBS was vital in the post-Ebola recovery phase, with community health workers identifying clusters of febrile illness and initiating rapid diagnostic responses, preventing further escalation [5]. Nepal, while not traditionally prone to hemorrhagic fevers, employed CBS to monitor diarrheal diseases and respiratory infections post-earthquake in 2015, demonstrating its flexibility and adaptability in non-epidemic scenarios.
However, long-term sustainability remains a challenge. In many instances, CBS systems falter after the initial donor funding ends or when community volunteers become demotivated due to lack of incentives or feedback from central health authorities. Moreover, without integration into national health information systems, CBS risks becoming a parallel structure that does not inform broader epidemiological trends. For example, in some areas of Sierra Leone, CBS reports were not consistently integrated with national surveillance databases, limiting their usefulness for coordinated outbreak response [6].
Training, technology, and trust are three pillars that influence the success of CBS. Consistent and standardized training of community focal points enhances data reliability. The use of mobile technologies, such as SMS-based reporting systems or smartphone apps, significantly improves realtime communication. Trust, both within the community and between the community and health authorities, is essential. Where communities view surveillance as intrusive or fear repercussions, reporting is often delayed or incomplete [7].
Interestingly, evidence suggests that CBS is more successful in detecting initial signs of outbreaks but less efficient at supporting complex follow-up or laboratory confirmation. Therefore, CBS should not replace formal surveillance systems but rather complement them as the first tier of detection, especially in hard-to-reach areas [8].
An important consideration is the replication of CBS models in varied sociocultural and geographical contexts. What works in a rural village in Uganda may not translate directly to an urban slum in India or a mountainous region in Peru. Hence, context-specific customization is crucial [9].
This evaluation also underscores the potential for CBS to serve dual functions not only as a surveillance tool but also as a mechanism for community education, risk communication, and resilience-building. For instance, during the COVID-19 pandemic, countries with pre-existing CBS structures were able to leverage these networks for contact tracing and health messaging [10].
Community-based surveillance holds significant potential as a first line of defense against emerging infectious diseases in lowresource settings. Its long-term effectiveness, however, depends on sustained funding, integration with national health systems, community ownership, and continuous training. CBS should be viewed not as a temporary measure during outbreaks, but as a permanent, adaptable infrastructure that enhances health security at the grassroots level.
To maximize its impact, policy makers and global health organizations should prioritize the institutionalization of CBS, invest in community engagement, and leverage digital tools to ensure real-time data collection and feedback. With proper support, CBS can evolve from a crisis-response tool into a cornerstone of preventive public health.
