The humanitarian crisis affecting the Rohingya population in Bangladesh’s Cox’s Bazar district remains a profound challenge, demanding sustained global attention and coordinated health interventions. As of May 2026, over one million displaced Rohingya individuals, alongside their Bangladeshi host community neighbours, continue to rely on comprehensive health support. Living in one of the world's largest and most densely populated refugee settlements, these communities face unique health vulnerabilities, making the work of organizations like the World Health Organization (WHO) absolutely critical for survival and well-being. ## Understanding the Rohingya Health Challenge The Rohingya refugees, primarily from Myanmar, sought refuge in Bangladesh following a brutal crackdown in 2017. Years later, their situation in Cox's Bazar remains precarious. The sheer density of the camps, coupled with inadequate sanitation, limited access to clean water, and often insufficient nutrition, creates an environment ripe for the rapid spread of infectious diseases. Children, pregnant women, and the elderly are particularly susceptible. Beyond immediate physical health, the prolonged displacement and trauma experienced by the Rohingya also necessitate significant mental health and psychosocial support services, which are integral components of a holistic health response. ## WHO's Vital Role in the Humanitarian Response In this complex setting, the WHO plays a central, multifaceted role. As the lead agency for the Health Sector, WHO is not only a service provider but also a crucial coordinator, ensuring that all health initiatives by various partners are harmonized and effective. Their support extends to disease surveillance, which involves systematically collecting, analysing, and interpreting health data to detect and monitor disease outbreaks. This is complemented by immediate outbreak response strategies, designed to contain and mitigate the impact of emergent health threats. Additionally, WHO focuses on maintaining the continuity of essential health services, ensuring that basic medical care, maternal health, and child health services remain accessible to those in need, despite the challenging circumstances. ## Battling Disease Outbreaks: Focus on Measles Measles, a highly contagious viral disease, poses a perennial threat in crowded settings like the Rohingya camps. Given its rapid spread and potential for severe complications, especially in malnourished children, measles response is a top priority. A comprehensive response typically involves a multi-pronged approach: rapid identification and isolation of suspected cases, robust vaccination campaigns to boost immunity, providing Vitamin A supplementation to reduce severity, and community-wide public health awareness campaigns. Despite ongoing efforts, maintaining high vaccination coverage and quickly containing new outbreaks requires constant vigilance and resources, especially as new children are born or populations shift within the camps. ## Strengthening Immunization Programs Beyond measles, regular immunization is paramount to prevent a host of other vaccine-preventable diseases. The WHO and its partners work tirelessly to strengthen routine immunization programs, ensuring children receive vaccines against polio, diphtheria, tetanus, pertussis (whooping cough), and other common childhood illnesses. Delivering these critical vaccines in a refugee setting presents significant logistical hurdles, including maintaining a cold chain for vaccine viability, reaching every child in a highly mobile population, and ensuring community understanding and acceptance of vaccination. These programs are vital not just for the refugees but also for protecting the host communities from potential spill-over of diseases. ## Preparedness and Surveillance: Keeping Watch Emergency preparedness is a cornerstone of the health response in Cox’s Bazar. This involves anticipatory planning and readiness for potential health crises, such as cholera outbreaks, dengue fever surges during monsoon seasons, or even novel pathogens. It encompasses developing contingency plans, pre-positioning medical supplies, training health workers, and establishing rapid response teams. A key tool in this effort is the Early Warning Alert and Response System (EWARS), a robust surveillance mechanism that collects data from health facilities across the camps. EWARS allows health authorities to detect unusual disease patterns or increases in cases early, enabling a swift and targeted response before an outbreak escalates into a wider epidemic. Similarly, the Health Resources and Services Availability Monitoring System (HeRAMS) helps map available health facilities and services, ensuring resources are allocated efficiently. ## The Power of Coordination and Partnerships Effective coordination is indispensable in a multi-stakeholder humanitarian operation. As the Health Sector lead, WHO is responsible for orchestrating the efforts of numerous national and international non-governmental organizations, UN agencies, and government bodies. This involves regular coordination and information-sharing meetings at various levels – from strategic discussions at the Cox's Bazar district level to practical, operational meetings at the camp level. These forums address service gaps, disseminate epidemiological updates, share best practices, and ensure a unified response to emerging health needs. The "4W" (Who, What, Where, When) information product is crucial here, providing a clear overview of partner activities and identifying potential overlaps or gaps in service delivery. ## Funding Challenges and Future Outlook The ongoing humanitarian response in Cox's Bazar is heavily reliant on international funding. The report for May 2026 highlights a persistent challenge: operational risks stemming from funding constraints and the potential for key implementing partners to scale down their activities. This is a critical concern, as reduced funding directly impacts the availability and quality of essential health services for a vulnerable population. The annual Joint Response Plan (JRP) for the Rohingya Humanitarian Crisis, which is updated regularly, outlines the overall needs and financial requirements across all sectors, including health. The Health Sector's strategic objectives (SO1, SO2, SO3) guide these efforts, focusing on ensuring access to comprehensive health services, controlling disease outbreaks, and strengthening public health systems. Sustained and predictable funding is vital to avert a further deterioration of the health situation and to continue building resilience within these communities. Looking ahead, the commitment of WHO and its partners remains unwavering. The goal is not just to respond to immediate emergencies but to build more resilient health systems that can withstand future shocks and provide dignified care. This requires continued advocacy for the Rohingya's right to health, innovative approaches to service delivery, and robust partnerships that can adapt to evolving challenges in this protracted crisis.
