Introduction

Infectious disease surveillance plays a vital role in protecting public health by detecting, monitoring, and responding to outbreaks in a timely and efficient manner. It serves as the backbone of disease control strategies, allowing healthcare systems and governments to identify patterns, assess risks, and implement interventions to reduce transmission and mortality. From seasonal influenza to emerging pandemics like COVID-19, robust surveillance systems are essential for global health security.[1,2].

Surveillance systems are broadly categorized into passive, active, and sentinel surveillance. Passive surveillance relies on healthcare providers to report cases to public health authorities, whereas active surveillance involves outreach by health officials to collect data directly from sources. Sentinel surveillance, on the other hand, uses selected institutions or providers to monitor specific diseases or populations, offering a representative snapshot of broader trends. [3,4].

Technological advancements have greatly enhanced infectious disease surveillance in recent years. The integration of digital health tools, artificial intelligence, and real-time data analytics enables faster detection of disease outbreaks and facilitates better decision-making. For instance, automated alert systems can now track abnormal spikes in disease incidence, while genomic sequencing helps identify and monitor new variants of pathogens infectious disease surveillance is a critical tool for safeguarding public health. As the world continues to face evolving threats, there is a pressing need for innovation, global cooperation, and equitable access to surveillance resources. Strengthening these systems ensures early warning, informed decision-making, and a faster, more effective response to both endemic and emerging infectious diseases [5,6].

Global collaboration is key in infectious disease surveillance, especially as pathogens do not respect borders. Organizations like the World Health Organization (WHO), Centers for Disease Control and Prevention (CDC), and local health departments work together to share data, build capacity, and develop coordinated responses. The International Health Regulations (IHR) framework is an example of a global treaty aimed at strengthening the world’s ability to prevent and respond to public health emergencies.[7,8].

Despite progress, several challenges remain, particularly in low-resource settings. These include inadequate laboratory infrastructure, lack of trained personnel, limited internet access, and underreporting of cases. Political instability and misinformation can further hinder data collection and timely responses. Addressing these gaps requires sustained investment in healthcare systems and international support for building local surveillance capacity. The COVID-19 pandemic has underscored the importance of timely and accurate disease surveillance. It revealed both the strengths and weaknesses of current systems, leading to increased investments in global health monitoring. Early detection of outbreaks, transparent communication, and coordinated public health interventions were proven to be crucial in mitigating the spread of the virus [9,10].
