Nigeria is facing a worsening meningitis outbreak in northern states, with health experts warning that current vaccines do not fully protect against the dominant Neisseria meningitidis serogroup C strain spreading rapidly.
Children aged one to 15 are most affected, while overcrowding and seasonal dry winds increase transmission risks, raising serious public health concerns across northern states within Africa’s meningitis belt.
Dr Jide Idris, Director-General of the Nigeria Centre for Disease Control and Prevention, disclosed this on Tuesday in Abuja during the 14th Ministerial Oversight Committee meeting on the Basic Health Care Provision Fund (BHCPF).
He expressed concern that available vaccine strains do not fully match the circulating serogroup C strain, noting that although vaccination remains important, additional strategies are needed to effectively control ongoing outbreaks.
Meningitis remains a major public health concern in Nigeria, especially during the dry season, with northern states most affected, according to the World Health Organization and national surveillance data.
Idris said outbreaks are largely driven by serogroup C, which has replaced serogroup A, while other strains such as W, X, and Y, alongside bacterial causes, account for fewer reported cases.
He noted that Nigeria is currently in a high-risk period for meningitis outbreaks, typically between December and April, when dry, dusty weather, overcrowding, and poor ventilation significantly increase transmission rates.
Idris said the agency has intensified surveillance and response nationwide, with laboratory testing conducted at the state level, while efforts continue to strengthen national laboratory capacity and improve detection and confirmation of cases.
According to him, meningitis is a serious infection affecting the membranes covering the brain and spinal cord, spreading through respiratory droplets during close contact, particularly in crowded or poorly ventilated environments.
He warned that the disease can progress rapidly and become fatal within hours if untreated, stressing that early diagnosis and prompt antibiotic treatment significantly improve survival rates and reduce complications.
Idris urged Nigerians to seek immediate medical attention if they experience symptoms such as sudden fever, severe headache, neck stiffness, nausea, vomiting, confusion, seizures, or sensitivity to light.
He cautioned that fever and headache during the dry season should not always be assumed to be malaria, advising people to seek proper diagnosis to avoid delayed treatment and possible complications.
He identified high-risk groups as children, young adults, and people in overcrowded environments, urging institutions to ensure proper ventilation and promptly report suspected cases to health authorities.
To reduce transmission, he advised avoiding overcrowded spaces, maintaining ventilation, covering the mouth when coughing or sneezing, and avoiding sharing utensils, while encouraging participation in vaccination campaigns.
