The Nigerian Meteorological Agency (NiMet) has issued a public health advisory warning that several northern states in Nigeria face a higher risk of Cerebrospinal Meningitis (CSM) as dry season conditions become more intense.
In a message shared on its official X account, NiMet explained that meningitis is a severe infection that affects the protective membranes surrounding the brain and spinal cord. The illness is commonly caused by the bacterium Neisseria meningitidis and spreads through respiratory droplets, particularly in crowded or poorly ventilated environments.
According to the agency, the states at high risk include **Sokoto State, Zamfara State, Kebbi State, Katsina State, Kano State, Jigawa State, Adamawa State, Gombe State, Bauchi State, Yobe State, and Borno State.
Residents in central regions were advised to remain alert and report any suspected symptoms quickly. Meanwhile, Plateau State, Oyo State, Cross River State, Edo State, Ekiti State, and Enugu State were classified as areas requiring lower vigilance.
NiMet urged Nigerians to stay informed, follow public health guidelines, and support community awareness campaigns. The agency emphasized that early awareness, vaccination, and prompt treatment are essential for saving lives.
The advisory also noted that meningitis can progress quickly and may become life-threatening within hours if left untreated. However, early diagnosis and timely antibiotic treatment significantly improve survival chances and reduce complications.
Groups considered most vulnerable include children and young adults, people living in overcrowded conditions, individuals exposed to hot, dry, and dusty environments, and those with weakened immune systems.
NiMet listed common symptoms to watch for, such as sudden high fever, severe headache, neck stiffness, nausea or vomiting, and sensitivity to light.
The agency stressed that vaccination remains one of the most effective ways to prevent meningitis. It also advised practicing good hygiene, washing hands regularly, avoiding the sharing of personal items like cups or utensils, and ensuring proper ventilation in homes, schools, and public spaces.
Nigeria has experienced repeated meningitis outbreaks over the years, particularly in northern states located within Africa’s “meningitis belt,” where hot, dusty weather and overcrowded conditions during the dry season increase the risk of transmission.
In April 2025, Nigeria received more than one million doses of meningococcal conjugate vaccines to address an outbreak that had already recorded over 800 cases and more than 70 deaths. The vaccination campaign targeted people between the ages of one and 29, the group most affected by the disease.
Health authorities say sustained vaccination efforts, improved disease surveillance, and early medical treatment remain vital to preventing deaths and controlling future outbreaks.
