The Nigeria Centre for Disease Control and Prevention (NCDC) has once again raised an urgent alarm on the dangers of diphtheria, a highly contagious but vaccine-preventable disease that has continued to pose a serious public health threat in different parts of the country. With rising cases reported in several communities, health experts are drawing attention to the need for renewed vigilance, immediate vaccination, and improved hygiene practices to protect families from a disease that spreads easily and can claim lives if not detected and treated early. Diphtheria is not a new disease, but the resurgence of outbreaks across Nigeria is a disturbing reminder of what happens when vaccination gaps exist and public awareness remains low. The disease, which spreads through direct contact with infected people, droplets from coughing or sneezing, or even by touching contaminated objects, has the capacity to move rapidly within households, schools, marketplaces, and other crowded places, leaving vulnerable children and adults exposed. Unlike some illnesses that require long incubation periods, diphtheria can escalate quickly, making it dangerous for anyone who does not receive prompt medical care.
Experts describe diphtheria as a bacterial infection that primarily affects the throat and upper airways, producing toxins that can damage organs and lead to severe complications such as breathing difficulties, heart failure, and nerve problems. The symptoms often begin with sore throat, mild fever, weakness, and swollen glands in the neck, but the disease can progress to more life-threatening conditions if untreated. The most concerning aspect is that many people mistake the early signs for ordinary infections, delaying treatment until it is too late. This is why NCDC is strongly urging Nigerians to take every cough, persistent sore throat, or unusual fever seriously and seek immediate attention at the nearest health facility. Early detection, reporting, and treatment, the agency emphasizes, save lives.
In recent months, Nigeria has witnessed an unsettling rise in diphtheria outbreaks, with several states confirming cases and health workers scrambling to contain the spread. The outbreaks have largely affected children, especially those in communities with low immunization coverage, but adults are not entirely safe either. Health experts warn that any lapse in vaccination, particularly for children under the age of five, leaves entire communities vulnerable to fresh waves of infection. The diphtheria vaccine, included in Nigeria’s routine immunization schedule, has proven to be highly effective, but access challenges, vaccine hesitancy, and misinformation have created gaps that the disease exploits.
The NCDC has therefore issued strong reminders that diphtheria is entirely preventable if individuals and communities prioritize vaccination. Parents are encouraged to ensure their children complete the required doses of the diphtheria vaccine, while adults who are uncertain about their vaccination history are advised to consult health facilities for guidance on catch-up doses. Vaccines remain the strongest shield against this disease, and widespread uptake is the only way to break the chain of transmission across Nigeria’s diverse communities.
Beyond vaccination, personal hygiene has emerged as a critical line of defense. Health authorities emphasize the importance of regular handwashing with soap and water, especially before eating or touching the face. In an era where respiratory infections have become a global concern, maintaining proper hygiene and avoiding close contact with individuals showing symptoms is essential. For communities that thrive on close interactions, such as marketplaces, schools, places of worship, and transportation hubs, this call for caution is particularly relevant. The practice of covering the mouth and nose while coughing or sneezing, frequent sanitization of frequently touched objects, and adherence to basic hygiene measures could be the difference between containment and widespread outbreaks.
The NCDC’s awareness campaign also highlights the role of communities in early reporting. The agency encourages Nigerians not only to seek care when feeling unwell but also to promptly report suspected cases to local health authorities. Delays in reporting suspected cases can prolong outbreaks, endanger vulnerable populations, and overwhelm already stretched health systems. By strengthening the culture of community responsibility, the chances of detecting, isolating, and treating diphtheria cases early enough to prevent fatalities become higher.
For health workers, the battle against diphtheria is more than a routine assignment. They are on the frontlines, risking exposure as they move from one outbreak hotspot to another. Doctors and nurses continue to call on Nigerians to support them by adhering to preventive measures, reducing misinformation, and cooperating with surveillance teams deployed to affected areas. Many cases, according to health experts, could have been avoided if communities embraced the full benefits of immunization programs rolled out nationwide.
The resurgence of diphtheria in Nigeria also underscores a broader concern about how preventable diseases continue to threaten lives in regions where vaccination rates are inconsistent. The global health community has stressed time and again that no child should die from a disease that can be prevented with a simple vaccine, yet outbreaks such as diphtheria remind the world that more work is needed to close immunization gaps. For Nigeria, this means investing more in awareness campaigns, reaching underserved communities, addressing vaccine hesitancy, and ensuring that no child or adult is left unprotected.
Citizens are also being reminded that diphtheria is not a disease to be taken lightly. In severe cases, the bacterial toxins can lead to paralysis, damage to the heart muscle, and even death. Survivors may carry long-term health complications, underscoring why prevention remains the safest and most effective strategy. Public health experts are therefore urging parents, guardians, teachers, religious leaders, and community heads to become advocates for vaccination and hygiene, reinforcing the message that protecting one life ultimately protects the entire community.
The recent call by NCDC is not just a public health announcement but a national appeal to responsibility. With social media playing a major role in information dissemination, the hashtags #StopDiphtheria, #HealthyLiving, and #NCDCNigeria have been trending, reminding Nigerians that the fight against diphtheria is collective. The agency’s efforts to raise awareness are part of a larger strategy to prevent not only diphtheria but also other vaccine-preventable diseases that continue to pose threats when communities let down their guard.
As Nigeria pushes forward with efforts to contain the outbreaks, the message remains simple but urgent: diphtheria is a vaccine-preventable disease. Every Nigerian has a role to play, whether by keeping vaccinations up to date, practicing proper hygiene, avoiding close contact with those who are sick, or seeking immediate care when unwell. It is a call for vigilance, a call for responsibility, and ultimately a call for life. In a country with millions of children whose futures depend on good health, the choice is clear—prevention is far better than cure. The lessons of past outbreaks must not be ignored, and the opportunity to stop diphtheria in its tracks lies within the power of every household, every community, and every individual who chooses to act today.
