Association between Meningococcal Meningitis and Santa Ana Winds in Children and Adolescents from Tijuana, Mexico: A Need for Vaccination

Rising meningitis in USA and Mexico: insights from the fatal outbreak

Meningitis, an inflammatory disease affecting the meningeal layers of the brain and the spinal cord, poses a significant public health concern globally. Most meningitis cases are caused by viral infections, bacterial infections being the second most common cause, while fungal or parasitic infections are deemed rare. Despite the decrease in bacterial meningitis because of vaccination and treatment, a recent meningitis outbreak in the United States and Mexico highlighted ongoing challenges. The current meningitis outbreak is caused by a pathogenic fungus and is associated with surgical procedures performed under spinal anaesthesia as reported by the Centers for Disease Control and Prevention (CDC) on the 11 May of 2023. Around 20 cases with clinical suspicion of meningitis, including two fatalities, have been attributed to this rampant outbreak. Timely diagnosis, utilising diagnostic modalities such as lumbar puncture and pathogen detection methods, is crucial for appropriate management. Iatrogenic meningitis must be avoided by enhancing surveillance, infection control procedures, and adherence to aseptic practices. To lessen the effects of meningitis and enhance patient outcomes, the WHO's roadmap and preventive interventions, such as targeted immunisations, are essential.

Serogroup B Meningococcal Sepsis and Meningitis Associated With Meningococcal Acute Otitis Media, and Paranasal Sinusitis in an Infant: A Case Report

Meningococcal disease (MD) is a potentially lethal condition. Typically, following infection, MD manifests with high fever, with signs and symptoms of severe septicemia with or without purpura, and in more than half of cases with meningitis. Acute otitis media (AOM) caused by Neisseria meningitidis has scarcely been reported, mostly without severe MD, and there are no reports of meningococcal paranasal sinusitis (PS). We present the case of a previously healthy 11-month-old infant who started with fever and cough and further developed intense irritability and right spontaneous purulent otorrhea, with subsequent increased fever and seizures. Blood, cerebrospinal, and middle ear fluid cultures were positive for N. meningitidis serogroup B, and a CT scan showed both maxillary and ethmoidal sinusitis. Intravenous ceftriaxone was administered for eight days, and three months following discharge, no sequelae were identified. This is the first report of a patient with MD associated with sepsis, meningitis, AOM, and PS.
