The Nigerian Meteorological Agency (NiMet) has issued a fresh public health alert, warning that worsening dry season conditions are increasing the risk of cerebrospinal meningitis (CSM) across several northern states in Nigeria.
In an advisory shared via its official X platform, NiMet described cerebrospinal meningitis as a severe infection that attacks the protective membranes surrounding the brain and spinal cord.
The disease is commonly caused by the bacterium Neisseria meningitidis and can spread rapidly through respiratory droplets, particularly in crowded or poorly ventilated environments.
According to the agency, 11 states are currently classified as high-risk areas: Sokoto State, Zamfara State, Kebbi State, Katsina State, Kano State, Jigawa State, Adamawa State, Gombe State, Bauchi State, Yobe State, and Borno State.
NiMet also urged residents in central parts of the country to remain vigilant and report suspected symptoms promptly, while Plateau State, Oyo State, Cross River State, Edo State, Ekiti State, and Enugu State were listed as low-vigilance zones.
“Stay informed, follow public health guidance, and participate in community awareness campaigns,” the agency advised, emphasizing that early awareness, vaccination, and prompt treatment remain the strongest defenses against the disease.
Health experts warn that meningitis can progress with alarming speed and may become fatal within hours if left untreated. However, early diagnosis and immediate antibiotic treatment significantly improve survival rates and reduce long-term complications.
NiMet identified the most vulnerable groups as children, young adults, people living in overcrowded settings, individuals exposed to dry and dusty conditions, and those with weakened immune systems.
Residents were advised to watch for symptoms such as sudden high fever, severe headache, neck stiffness, nausea, vomiting, and sensitivity to light.
The agency further stressed that vaccination remains one of the most effective preventive measures against meningitis. It encouraged regular handwashing, avoiding the sharing of personal items such as cups and utensils, and ensuring proper ventilation in homes, schools, and public spaces.
Nigeria continues to face recurring meningitis outbreaks, especially in northern states located within Africa’s meningitis belt, where hot, dusty weather during the dry season often accelerates transmission.
In April 2025, Nigeria received over one million doses of meningococcal conjugate vaccines to contain an outbreak that had already recorded more than 800 cases and over 70 deaths nationwide.
The vaccination campaign primarily targeted people aged one to 29 years, the demographic most affected by the disease.
Public health authorities maintain that sustained vaccination drives, stronger surveillance systems, and early medical intervention are critical to reducing fatalities and preventing future outbreaks
