Hantavirus in Nigeria: NCDC Confirms No Cases, But Vigilance Remains Key
By Fred Ezeh, Abuja
The Nigeria Centre for Disease Control and Prevention (NCDC) has officially confirmed that there is currently no evidence of hantavirus cases in Nigeria. This announcement comes amid global attention on the virus following a reported cluster of cases linked to the Andes virus strain in other regions.
What Is Hantavirus and Why Should You Care?
Hantaviruses are a family of viruses primarily carried by rodents, particularly rats and mice. Humans can become infected through direct contact with infected rodents or exposure to their urine, droppings, saliva, or contaminated dust particles. The virus does not spread through the air like influenza; instead, infection typically occurs when dried rodent excreta are disturbed and inhaled, or when contaminated materials touch broken skin or mucous membranes.
While hantavirus infections are rare, they can be severe. The most dangerous form, Hantavirus Pulmonary Syndrome (HPS), has a mortality rate of up to 38% in some outbreaks. Symptoms often begin with fever, fatigue, muscle aches, headache, and gastrointestinal issues. In severe cases, the disease progresses rapidly to difficulty breathing and respiratory failure, requiring intensive medical care.
NCDC’s Response: Monitoring and Preparedness
The NCDC has assured the public that it is closely monitoring the global situation and maintaining enhanced surveillance for emerging infectious diseases. The agency’s statement emphasized that the current global cluster has been linked to the Andes virus strain, which is unique because limited human-to-human transmission has been documented, primarily through close contact with an infected person. This is unlike most hantaviruses, which are almost exclusively transmitted from rodents to humans.
Despite the lack of cases in Nigeria, the NCDC has issued a public health advisory to keep the population informed and prepared. The overall risk to the general public remains low, but proactive measures are essential to prevent any potential introduction or spread of the virus.
Practical Steps to Protect Yourself and Your Community
The NCDC has outlined several actionable recommendations for Nigerians to reduce the risk of hantavirus and other rodent-borne diseases:
1. Maintain a Clean Environment
Rodents are attracted to clutter, food scraps, and standing water. Regularly clean your home, especially kitchens and storage areas. Seal cracks and holes in walls, floors, and foundations to prevent rodents from entering.
2. Store Food Properly and Dispose of Waste Safely
Keep food in sealed containers, and do not leave pet food out overnight. Use covered trash bins and dispose of garbage regularly to avoid attracting rodents.
3. Avoid Direct Contact with Rodents and Their Droppings
Never touch live or dead rodents with bare hands. If you find rodent droppings, nests, or dead animals, do not sweep or vacuum them dry, as this can aerosolize the virus. Instead, wear gloves and a mask, spray the area with a disinfectant (like bleach solution), and carefully wipe up the material.
4. Use Protective Measures When Cleaning Infested Areas
If you are cleaning a space that has been infested with rodents, wear rubber gloves, a mask (N95 if available), and long sleeves. Ventilate the area by opening windows for at least 30 minutes before cleaning. Dispose of contaminated materials in sealed plastic bags.
5. Practice Regular Hand Hygiene
Wash your hands thoroughly with soap and water after any potential contact with rodents, their droppings, or contaminated surfaces. Alcohol-based hand sanitizers can be used when soap is not available.
6. Strengthen Infection Prevention in Healthcare Facilities
Healthcare workers should maintain optimal infection prevention and control measures, including proper use of personal protective equipment (PPE) and safe handling of patients with respiratory symptoms of unknown origin.
Why This Matters Beyond Hantavirus
The NCDC’s proactive stance on hantavirus is part of a broader strategy to strengthen Nigeria’s preparedness for emerging infectious diseases. Rodent-borne illnesses like Lassa fever, leptospirosis, and plague are already present in parts of West Africa. The same hygiene and environmental control measures that prevent hantavirus also reduce the risk of these other diseases. By staying vigilant, Nigeria can protect public health and avoid the kind of outbreaks that overwhelm healthcare systems.

Conclusion: Stay Informed, Stay Safe
The NCDC has reiterated its commitment to safeguarding public health and will continue to provide timely updates as the situation evolves. For now, Nigerians can rest assured that there is no immediate threat from hantavirus. However, the best defense against any infectious disease is a combination of awareness, good hygiene, and community cooperation. By following the simple steps outlined above, you can protect yourself, your family, and your community.
