Across Africa, health authorities are sounding alarms as Ebola Virus Disease (EVD) reemerges with renewed intensity in the Democratic Republic of the Congo (DRC) and crosses into Uganda, prompting Nigeria to activate its most robust outbreak response in a decade. While the risk of importation remains moderate, the rapid geographic spread of the virus underscores a critical moment for public vigilance and preparedness.
With Nigeria’s borders porous to travelers from Central and East Africa, the Nigeria Centre for Disease Control and Prevention (NCDC) has elevated its surveillance, diagnostics, and public education campaigns to prevent a repeat of the 2014 epidemic that claimed seven lives and cost millions in containment efforts. This time, the stakes are higher: the DRC’s current outbreak is the second largest in history, and Uganda’s recent case marks the first cross border spillover in years.
What Happened
The latest Ebola flare-ups began in the DRC’s North Kivu and South Kivu provinces, where over 3,000 confirmed or probable cases have been recorded since 2022, according to the World Health Organization (WHO). In August 2024, a case was confirmed in Uganda’s Mubende district, the country’s first in over a decade, raising concerns about regional spillover. While the virus has not yet reached Nigeria, the NCDC has classified the risk of importation as "high" due to frequent travel between affected areas and Nigeria’s major urban centers.
Why Public Health Officials Are Concerned
Ebola Virus Disease remains one of the deadliest known pathogens, with case fatality rates historically ranging from 50% to 90% depending on the outbreak and access to care. The current DRC outbreak has already resulted in over 2,000 deaths, and the Uganda case demonstrates that even well-controlled regions are vulnerable to sudden importations. Nigeria’s experience in 2014—when a Liberian traveler brought Ebola to Lagos, sparking a chain of transmission that required a national emergency response—serves as a stark reminder of how quickly the virus can spread in densely populated, mobile societies.
The NCDC’s Director-General, Dr. Jide Idris, emphasized the urgency in a recent statement: "The combination of high population mobility, urban density, and porous borders creates a perfect storm for Ebola transmission. Our surveillance systems are now operating at peak capacity to detect any hint of the virus before it gains a foothold."
Symptoms or Risk Factors
Ebola symptoms typically appear 2 to 21 days after exposure and progress rapidly from flu-like illness to severe complications. Early signs include:
- High fever
- Severe headache
- Muscle and joint pain
- Fatigue and weakness
- Sore throat
- Vomiting and diarrhea
As the disease advances, patients may develop:
- Unexplained bleeding (e.g., from gums, nose, or injection sites)
- Rash
- Organ failure
- Shock
The virus spreads through direct contact with the blood, vomit, feces, or other bodily fluids of infected individuals or contaminated surfaces. It does not spread through casual contact, air, water, or food, but close family care, traditional burial practices, and unprotected healthcare interactions pose significant risks.
Who May Be Affected
The current outbreaks primarily threaten communities in eastern DRC and western Uganda, particularly in areas with limited healthcare infrastructure. However, the risk extends to:
- Travelers: Individuals visiting or transiting through high-risk regions in DRC, Uganda, or neighboring countries.
- Healthcare workers: Those providing care in facilities with inadequate infection prevention measures.
- Family caregivers: Close contacts of Ebola patients, especially during the symptomatic phase.
- Border communities: Residents in Nigerian states with high cross-border traffic, such as Adamawa, Borno, and Taraba.
Government or WHO Response
Nigeria’s response is coordinated through the NCDC’s National Ebola Preparedness and Response Plan, which includes:
- Enhanced screening: Temperature checks and symptom questionnaires at airports, land borders, and seaports, with mandatory isolation for suspected cases.
- Rapid response teams: State-level units trained to isolate patients, trace contacts, and coordinate with federal authorities within 24 hours of detection.
- Laboratory capacity: Seven regional labs equipped with PCR testing to confirm cases within hours, supported by the WHO’s Global Outbreak Alert and Response Network (GOARN).
- Public messaging: Multilingual campaigns via radio, social media, and community health workers to counter misinformation and promote early care-seeking.
The WHO has deployed technical experts to DRC and Uganda, while the Africa Centres for Disease Control and Prevention (Africa CDC) has activated a regional emergency operations center to coordinate cross-border surveillance and response efforts.
Prevention and Safety Guidance
Preventing Ebola requires a combination of personal vigilance, community awareness, and adherence to public health measures. The NCDC recommends the following steps for individuals and families:
- Avoid non-essential travel to high-risk areas: Postpone trips to eastern DRC, western Uganda, and other regions with active Ebola transmission. Check travel advisories from the NCDC and WHO before planning any journey.
- Practice rigorous hygiene: Wash hands frequently with soap and water for at least 20 seconds, or use alcohol-based hand sanitizers. Avoid touching your face, especially your eyes, nose, and mouth.
- Use protective measures in healthcare settings: If visiting a clinic or hospital in a high-risk area, insist on proper infection control practices, including glove use and surface disinfection.
- Monitor health closely: Seek immediate medical attention if you develop fever, headache, or gastrointestinal symptoms within 21 days of returning from a high-risk region. Inform healthcare providers about your travel history.
- Report suspicious cases: If you suspect someone has been exposed or is showing symptoms, isolate them and contact the NCDC’s 24/7 hotline at 6232 or WhatsApp at 07087110839. Do not attempt to transport the individual yourself.
- Support safe burial practices: Avoid participating in traditional funeral rites involving washing or touching the body of a deceased person from a high-risk area.
What Readers Should Know
Ebola is not a disease of the past. While Nigeria has not recorded a case since 2014, the virus’s persistence in neighboring countries demands renewed caution. The difference between containment and an outbreak lies in early detection and community cooperation. Missteps in 2014—such as delayed reporting and stigma against healthcare workers—exacerbated the crisis. Today, Nigeria’s systems are stronger, but complacency remains the greatest threat.
For travelers, the key is preparation. Register with your embassy before trips to high-risk areas, carry a travel health kit with sanitizers and masks, and maintain a list of local healthcare facilities. For communities, the message is clear: Ebola thrives in silence. Reporting symptoms early saves lives, and every second counts.
The NCDC’s message is simple: "Be alert, not afraid. Act responsibly, and together, we can keep Ebola out of Nigeria."

Frequently Asked Questions
Can Ebola spread through the air or casual contact?
No. Ebola spreads only through direct contact with the blood, vomit, feces, or other bodily fluids of infected individuals or contaminated surfaces. It does not spread through air, water, or food, and casual contact like sitting near an infected person does not pose a risk.
How long should travelers monitor their health after returning from a high risk area?
Travelers should monitor their health for 21 days after returning from a high risk region, as this is the maximum incubation period for Ebola. Seek immediate medical attention if fever, headache, or gastrointestinal symptoms develop.
What should I do if I suspect someone has been exposed to Ebola?
Isolate the individual immediately and contact health authorities via the NCDC’s hotline at 6232 or WhatsApp at 07087110839. Do not attempt to transport the person yourself, as this could expose others to the virus.
Is there a vaccine for Ebola?
Yes. Several Ebola vaccines have been developed and deployed in outbreak settings, including the Ervebo vaccine, which is approved for use in high risk populations. The WHO and Africa CDC recommend vaccination for healthcare workers and communities in affected areas.
How effective is Nigeria’s current surveillance system in detecting Ebola?
Nigeria’s surveillance system has improved significantly since 2014, with enhanced screening at borders, rapid response teams in all states, and laboratory capacity to confirm cases within hours. The NCDC’s integration with the WHO’s GOARN network further strengthens detection and response.
