Despite handling the majority of malaria cases in Nigeria, private health providers report almost none of their patients to national surveillance systems for record-keeping, leaving the country blind to the true scale of its deadliest infectious disease (malaria).
Every day, millions of Nigerians seek malaria treatment from private pharmacies, patent medicine vendors, and clinics. These facilities dispense antimalarial drugs, conduct tests, and send patients home. But there is a critical step they almost never take: reporting these cases to health authorities.
According to the ACTwatch Lite Nigeria 2024 study, which surveyed the private antimalarial market across Lagos, Abia, and Kano states, revealed a surprising reality. Case reporting in the private sector remains extremely low, even among registered outlets that are legally required to report cases. And among those who do report, supervision is minimal. This reporting gap creates a dangerous blind spot in Nigeria’s fight against malaria. The country cannot track outbreaks it doesn’t know about, it cannot measure progress it cannot see, and it cannot allocate resources to areas whose burden remains invisible.
From the report of ACTwatch Lite Nigeria 2024, the private sector’s dominance in malaria treatment makes this silence particularly troubling. Patent and Proprietary Medicine Vendors (PPMVs) remain the main outlet type for antimalarial distribution across all three states surveyed. These vendors account for the largest market share in malaria treatment, far outpacing government health facilities. When a patient visits a government hospital with malaria, that case enters the national health information system. Health officials can track where cases are occurring, identify outbreak patterns, and measure whether interventions are working. But when the same patient visits a private pharmacy or PPMV, that case disappears from official records.
The implications extend far beyond simple data collection. Nigeria’s National Malaria Strategic Plan depends on accurate surveillance data to guide interventions. The Federal Ministry of Health uses case reports to determine where to deploy resources, which communities need intensified prevention efforts, and whether control measures are succeeding.
International donors and development partners also rely on surveillance data when making funding decisions. Organizations like the Global Fund, President’s Malaria Initiative (PMI), and various UN agencies need evidence of disease burden and programme impact to justify continued investment. Incomplete data makes it harder for Nigeria to demonstrate need and secure the external funding that supplements domestic malaria spending.
The World Health Organization (WHO) recommends that countries maintain robust disease surveillance systems that capture at least 80% of cases. Nigeria’s system, which misses most private sector cases, falls far short of this standard. This gap undermines the country’s ability to pursue malaria elimination goals effectively.
The consequences of poor surveillance have played out repeatedly in Nigeria’s malaria response. During the rainy season when transmission intensifies because of intense mosquito availability, health authorities struggle to identify which communities are experiencing the worst outbreaks. By the time patterns become visible through hospital admissions and deaths, the outbreak has already gone high, and laid havoc. At this juncture, resource allocation also suffers because of lack of accurate data. State governments and local health departments make decisions about where to distribute bed nets, conduct indoor residual spraying, and position malaria commodities based on reported case data. When large portions of cases go unreported, these interventions may miss the communities that need them most.
The surveillance gap also affects policy evaluation by relevant bodies/authorities. Nigeria has invested heavily in various malaria control strategies over the past decade. These include mass distribution of insecticide-treated nets, seasonal malaria chemoprevention for children, and efforts to increase diagnostic testing before treatment. Without comprehensive case data, measuring the impact of these expensive interventions becomes extremely difficult.
Meanwhile, several factors contribute to the low reporting rates in the private sector. Many PPMVs and small pharmacies lack the systems, staff, and sometimes, time needed for consistent reporting. Filling out forms and submitting data takes time away from serving customers in busy outlets, especially where profit margins are not much. Some private providers also lack knowledge or clarity about reporting requirements. While large pharmacies and registered clinics understand their obligations, many PPMVs operate with limited training in health system responsibilities. They see themselves primarily as business-people rather than components of the national health infrastructure or stakeholders that could contribute to the country’s health sector.
Additionally, Fear of regulatory consequences may also discourage reporting. Some providers worry that submitting data will invite unwanted scrutiny from health regulators or tax authorities. In an environment where regulatory enforcement is often inconsistent and sometimes selective, many small businesses prefer to remain invisible, especially those in the rural areas. Furthermore, the minimal supervision of those who do report compounds the problem. The ACTwatch Lite study found that even outlets making efforts to submit data receive little feedback or support from health authorities. Without regular supervision visits, technical support, or acknowledgment of their reporting efforts, providers have little interest or incentive to maintain the practice.
Nevertheless, technology could help address some reporting barriers in this era of digitization. Digital reporting systems using mobile phones or tablets could reduce the time burden and even costs compared to paper-based systems. Real-time data transmission would eliminate the need for physical submission of reports. Automated systems could provide immediate feedback to providers, creating a sense of participation in the broader health system. Several Nigerian states have experimented with digital health reporting platforms. These systems allow private providers to submit malaria case data through SMS or Smartphone Apps. Early results show promise, with participating outlets reporting regularly once the initial setup is complete. However, these initiatives remain limited in scope and have not achieved a reasonable scale.
Incentive structures also need examination. Currently, private providers bear the cost and effort of reporting while receiving little or no tangible benefit. Some countries have addressed this by linking reporting compliance to business licensing renewal, creating regulatory motivation. Others provide small financial incentives for consistent reporting or public recognition for high-performing outlets. Nigeria must adopt this holistically if it is really ready for accurate malaria data collection.
Professional associations representing pharmacists and PPMVs could play a larger role in promoting reporting compliance. These organizations have direct relationships with private providers and could integrate reporting expectations into their professional standards and training programmes.
The supervision gap requires particular attention. Health authorities at state and local levels need adequate staffing and resources to conduct regular supportive supervision of private sector outlets. These visits should focus on technical assistance rather than disciplinary enforcement, helping providers improve their practices while reinforcing reporting expectations. Supervision also serves a quality assurance function. When health workers visit private outlets regularly, they can verify that providers are following treatment guidelines, stocking quality-assured antimalarials, and conducting appropriate diagnostic testing. This broader engagement makes reporting feel like part of a supportive relationship rather than an isolated bureaucratic requirement.
The COVID-19 pandemic demonstrated both the importance of robust disease surveillance and the possibility of rapid system improvements. When Nigeria needed to track coronavirus cases, authorities quickly mobilized new reporting mechanisms and engaged private sector providers in surveillance efforts. While malaria lacks the same sense of emergency, the pandemic showed that Nigerian health systems can adapt when properly motivated and supported.
Integration with existing data systems offers another avenue for improvement. Many private pharmacies and clinics already maintain business records of products sold and services provided. If these systems could be linked to national health surveillance platforms, reporting would become automatic rather than requiring separate data entry.
Regional variation in reporting compliance also deserves attention. Some states have achieved better private sector reporting than others through consistent engagement with provider associations and sustained political commitment to surveillance improvement. Understanding what works in these settings could inform strategies for other states.
The financial implications of poor surveillance extend beyond immediate case management. Nigeria’s pharmaceutical market for antimalarials is reportedly worth billions of naira annually. Understanding true consumption patterns would help manufacturers and distributors plan more effectively, potentially reducing costs through better supply chain management.
Insurance schemes and health financing mechanisms also need accurate malaria data. As Nigeria expands health insurance coverage through schemes like the National Health Insurance Authority (NHIA), knowing the true burden of malaria will be essential for setting budgeting for claims.
Academic researchers and public health scientists face significant challenges when trying to study malaria in Nigeria due to incomplete surveillance data. This limits the country’s ability to generate the evidence needed to refine control strategies and measure programme effectiveness.
The antimalarial drug market operates largely without surveillance oversight. The ACTwatch Lite study found that the market is diverse, with no single predominant manufacturer or brand across the three states surveyed. This diversity suggests a competitive market, but without case reporting, authorities cannot monitor for unusual patterns that might indicate drug resistance or counterfeit product circulation.
The study also revealed complaints between antimalarial availability and testing access in some states. In Abia and Lagos, antimalarials are readily available through PPMVs, but malaria testing is uncommon in these same outlets. Only in Kano do PPMVs commonly offer both testing and treatment because of pocket friendly cost of testing. However, without case reporting, these regional variations in service availability remain invisible to policymakers.
Drug resistance monitoring depends heavily on surveillance data. If certain antimalarials begin losing effectiveness due to parasite resistance, this will first appear as treatment failures in surveillance systems. Without comprehensive reporting, Nigeria might miss early warning signs of resistance development, allowing resistant strains or viruses to spread before interventions can be implemented.
The economic burden of unreported cases also remains unknown. Malaria costs Nigerian families billions in treatment expenses and lost productivity annually. But without knowing how many cases occur outside the formal health system, economists cannot accurately calculate these costs or model the potential savings from improved control measures.
Private sector providers themselves would benefit from better integration into surveillance systems. Access to aggregated data about disease patterns in their communities would help them anticipate demand, stock appropriate products, and provide better advice to patients. Currently, they operate without this valuable market intelligence, which is a setback but unknown to them.
Patient trust in the health system could also improve through better surveillance. When people see that authorities are tracking disease patterns and responding with targeted interventions, confidence in government health programmes increases. The current disconnect between where people seek care and what the health system monitors may contribute to public doubt about official health data.
The path forward requires commitment; not only from the government but multiple stakeholders. Government health authorities must invest in surveillance infrastructure and make private sector engagement a priority, while professional associations need to emphasize reporting as a professional responsibility. Technology companies should develop user-friendly reporting tools tailored to Nigerian contexts for seemingly malaria data collection.
International partners supporting Nigeria’s malaria control efforts should also prioritize surveillance strengthening. Current funding often focuses on direct interventions like bed net distribution or drug procurement while giving less attention to the data systems needed to guide these interventions effectively.
Training institutions for health professionals need to incorporate surveillance responsibilities into their curricula. Future pharmacists, nurses, and community health workers should graduate with understanding that case reporting is not optional but essential to effective disease control, especially malaria.
The regulatory framework may also need updating. Current requirements for private sector reporting exist on paper but lack effective enforcement patterns or mechanisms. Clearer regulations with both incentives for compliance and consequences for non-compliance might improve participation rates. However, regulation alone cannot solve the problem. A punitive approach risks driving small informal providers further underground. Instead, Nigeria needs a balanced strategy combining supportive supervision, technical assistance, appropriate incentives, and streamlined reporting processes that respect the operational realities of private sector outlets.
The ACTwatch Lite study provides a baseline against which future progress can be measured. By documenting current reporting rates and identifying barriers, the research creates a foundation for targeted interventions. Future surveys can track whether these interventions are working and where additional efforts are needed. The study’s focus on three diverse states also reveals that solutions must account for regional variation. What works in Kano may not work in Lagos. Effective strategies will likely require state-level customization while maintaining national standards and data compatibility.
Conclusion
Nigeria cannot eliminate malaria or even effectively control it without (accurately) knowing where cases are occurring. The current situation where most malaria treatment happens in a surveillance blind spot is not sustainable. Every unreported case represents not just missing data but a lost opportunity to prevent future cases through targeted intervention.
The good news is that solutions exist and have worked in similar contexts. Other countries with large private health sectors have successfully integrated these providers into national surveillance systems. Nigeria can learn from these experiences while adapting approaches to local realities.
The malaria burden Nigeria carries is enormous. The disease kills thousands of children annually, sickens millions more, and drains billions from the economy. Improving surveillance will not by itself cure malaria, but it is an essential prerequisite for the targeted, and evidence-based interventions that will ultimately bring the disease under control.
Breaking the silence in Nigeria’s private health sector must become a national priority. The country’s malaria control efforts will remain hindered until health authorities can see the full picture of where the disease strikes and how people respond to it. Only then can Nigeria deploy its resources effectively and measure whether its significant investments in malaria control are truly making a difference.
