Whether a humanitarian crisis is due to a natural disaster, a conflict, or a forced displacement scenario, the conditions of these events cause situations in which diseases with explosive epidemic potential, such as malaria, spread easily. For instance, humanitarian crises disrupt healthcare systems, overcrowd housing, and limit access to resources, all of which increase the risk of malaria infection. Plasmodium parasites cause malaria, and infected Anopheles mosquitoes transmit these parasites through their bites. The disease continues to be one of the most prominent public health challenges in the world, particularly in endemic malaria areas. We must make a concerted effort to ensure sustainable malaria control during humanitarian crises. This will require the concerted efforts of all involved in tackling such crises.
Understanding Malaria in Humanitarian Crises
Impact of Humanitarian Crises on Malaria Spread
Social suffering associated with humanitarian crises disrupts health systems and increases vulnerability to disease. The following are some of the reasons why malaria risk increases:
- Displacement and overcrowding: Internally displaced populations often live in temporary shelters and informal camps, facing contested and inadequate access to basic sanitation and health care. Mosquito bites, and thus malaria, are more common in overcrowded conditions.
- Disruption of Healthcare Services: Healthcare infrastructure often breaks down in crises, reducing access to malaria diagnoses and treatment. Supply chains for essential medicines and insecticide-treated nets (ITNs) can be interrupted.
- Environmental Changes: Mosquito breeding sources occur naturally in floods or cyclones that create stagnant water pools and can be an ideal breeding context for mosquito transmission.
- Economic Hardship: Volatility in the economy can stop populations from being able to afford preventive measures and deplete the ability to pay for Now that’s damage.

Rapid Response Strategies for Malaria Control
1. Emergency Vector Control
Insecticide-treated nets (ITNs) and Indoor Residual Spray (IRS)
We must distribute insecticide-treated nets (ITNs) and implement indoor residual spraying (IRS) without delay to impede malaria transmission. ITNs protect against mosquito bites, while IRS uses an insecticide spray to kill mosquitoes by coating indoor walls and roofs. They both act to reduce malaria transmission by killing mosquitoes or keeping them away which reduces the population of mosquitoes.
- ITN Distribution: We should supply insecticide-treated nets (ITNs) to all households, particularly in high-risk areas, and provide adequate information on their use and maintenance.
- IRS Implementation: We should conduct community-wide indoor residual spraying (IRS) in high-density areas, ideally led by local health authorities. It’s essential to monitor and report the progress and outcomes of IRS campaigns. We must compare the expected positive results with other options and address any challenges that arise to ensure continuous improvement of the process.
Larviciding
This is to water sources such as ditches that facilitate mosquito larval development. Larviciding offers a particularly effective strategy for combating the mosquitoes that emerge after floods or other disasters in areas where water remains stagnant.
- Targeted Application: Apply larvicides by air or by ground to highly active breeding sites using a method that relies on one or more of the following: persistent or residual activity of the larvicide, physical displacement of the leaves, or specific action against larval form. Insights into the developmental stage of the larvae can guide the selection of each of these methods. Were the mosquitoes collected in larval or pupal stages? If larval stage, was it early larval stage or late larval stage? The use of a specific mosquito species indicator should also be considered. Which adult mosquito was collected? In addition to the use of oviposition attractants, it is important to note certain insights into the development stage of the larvae collected.
- Community Engagement: Get local communities to help identify and report potential breeding sites. Local engagement enhances the success of targeted larviciding.
2. Strengthening Healthcare Services
Mobile Health Units
This might involve using mobile health units where there are health service access gaps, for malaria diagnosis, treatment, and prophylaxis in hard-to-reach populations.
- Decision gate step. Mobile Clinics: Each mobile clinic should be equipped with rapid diagnostic tests (RDTs) and antimalarial drugs. Healthcare workers must be trained to identify and treat malaria cases and to rescue victims of emergency events.
- Outreach programs: Conduct outreach programs to educate the population about the prevention and treatment of malaria, using mobile units to provide health education and distribute ITNs.
Supply Chain Management
The malaria-control continuum. Maintain the supply chain of malaria-control commodities; have all RDTs, antimalarial drugs, and ITNs available and delivered.
- Stock monitoring: Keep an eye on stocks and maintain a regular supply with humanitarian organizations.
- Logistical Coordination: Work with local and international partners, and leverage information technology to efficiently execute the movement of malaria control commodities from several distribution sites. Vaccine Coordination: Establish effective coordination with governments, regional organizations, the World Health Organisation, and pharmaceutical companies to ensure appropriate vaccine distribution throughout the region. Namibia Priorities: Coordination: Develop a coordination framework that addresses these principles, including interjection, internal-external, local-central, and cross-sectoral coordination. Advocacy and Communication: Generate enduring impact by strengthening messages, communicating progress, and engaging the public.
3. Surveillance and Data Management
Disease Surveillance
Building strong surveillance systems is an important first step for understanding changes in target populations. This includes monitoring malaria trends and evaluating the impact of interventions to make sure that insecticide-treated nets and drugs are just as powerful now as they have always been. Track cases of illness and mortality, as well as the density of vector populations, to guide these response strategies.
- Data collection: Install real-time surveillance systems that track malaria cases and vector population, and maximize mobile technology and collection and analysis.
- Epidemiological Analysis: Identify areas where malaria is most prevalent the ‘hotspots’ of malaria epidemiology and how those patterns are changing over time; use these data to plan targeted interventions and funding.
Monitoring and Evaluation
You need to check the results of the malaria control measures regularly. Are the current interventions working? Based on this feedback and data, I think that some strategies should be adjusted.
- Impact Assessment: Conduct a regular (every month/year) impact assessment to determine the effectiveness of continuous use of ITNs and IRS, as well as other malaria control interventions. The results are also used to refine the response and improve performance.
- Feedback Mechanisms: Design feedback mechanisms for collecting information from affected communities and doctors and nurses, and address the challenges the interventions face through the feedback on the ground.
4. Community Engagement and Education
Health Education Campaigns
Health education programs that emphasize the value of malaria prevention and treatment are essential. Inform your community about the merits of sleeping under ITNs, the correct usage of antimalarial drugs, and the need to promptly seek medical attention.
Communication Strategies: Use multiple communication methods, such as community meetings, radio broadcasts, and printed leaflets. Ensure that messages are disseminated in local languages and tailored to the local context.
Second, behavioral change: promote understanding of the benefit of malaria prophylaxis and correct misunderstandings about the consequences of drug treatment of the disease. Engage traditional and new leaders in your community in promoting health education efforts.
Community Involvement
Involving local communities more meaningfully in malaria control can help to increase intervention effectiveness and sustainability. Support the work of communities in malaria prevention and response.
- Volunteer Programs: Launch community volunteer programs to engage more people in malaria control interventions. Organize and train volunteers to assist with distributing ITNs, providing health education, and identifying cases.
- Partnerships: Collaborate with local organizations, faith-based organizations, and community-based organizations to effectively scale up malaria control efforts, making use of existing community networks to improve outreach and support.
Humanitarian interventions against malaria must combine rapid responses with long-term measures to provide an effective and coordinated approach to reducing the burden of the disease within complicated humanitarian settings. Furthermore, improved control of the disease vector must go hand in hand with effective healthcare services. In addition, community engagement and strengthened surveillance, as outlined above, are crucial for achieving sustainable outcomes.
Moving forward, there will be a need for ongoing research and innovation to develop and implement new strategies for malaria control while humanitarian crises persist as a major threat to global health. Funding effective malaria-control strategies and international cooperation are important steps toward the goal of drastically reducing the global burden of malaria. Furthermore, these efforts are crucial for improving health in crisis-affected countries.
