The Nigerian Meteorological Agency (NiMet) has raised an alarm over a high risk of meningitis outbreak in the north, as dry and dusty weather conditions persist across the region.
In a Meningitis Risk Advisory released on Thursday, the agency said the disease can spread rapidly and become fatal within hours if not treated early.
Cerebrospinal Meningitis (CSM) is a serious infection affecting the brain and spinal cord, commonly caused by the bacterium Neisseria meningitidis. It spreads through respiratory droplets, especially in crowded or poorly ventilated places.
Common symptoms of meningitis include sudden high fever, severe headache, neck stiffness, nausea or vomiting, and sensitivity to light.
According to the agency’s surveillance map for March 2026, 11 states fall under the high-risk category.
The affected states include Sokoto, Zamfara, Kebbi, Katsina, Kano, Jigawa, Adamawa, Gombe, Bauchi, Yobe and Borno.
NiMet noted that environmental conditions such as dust and humidity levels currently favour the emergence and spread of the disease in those areas.
“The disease can progress rapidly and may become life-threatening within hours if untreated. However, early diagnosis and prompt antibiotic treatment greatly improve survival and reduce complications,” the advisory reads.
Residents in central parts of the country are advised to maintain moderate vigilance and report suspected symptoms early.
The agency also listed Plateau, Oyo, Cross River, Edo, Ekiti and Enugu among states with lower vigilance levels.
NiMet said children, young adults and people living in overcrowded conditions face the highest risk of infection.
“Individuals exposed to dry, dusty environments and persons with weakened immune systems are also particularly vulnerable,” the agency said.
To reduce the risk of infection, the agency urged Nigerians to take preventive measures such as vaccination, maintaining good hygiene and avoiding overcrowded spaces.
“Get vaccinated where available; maintain good personal hygiene; avoid overcrowded and poorly ventilated spaces; and seek immediate medical attention if symptoms such as high fever, severe headache or neck stiffness occur,” NiMET said.
The agency added that public awareness and early treatment remain critical to preventing deaths from the disease.
“Protect yourself and your community. Early awareness, vaccination, and prompt treatment save lives,” it said.
