Meningitis: The Deceptive Symptoms and How to Differentiate Between Serotypes

With the arrival of autumn and winter, respiratory infections are on the upswing. Among them, meningococcal meningitis poses a grave threat, especially to children with weakened immune systems. This insidious disease, caused by the meningococcus bacterium, can trigger meningitis and sepsis, leading to life-threatening complications with the most severe cases being fatal within 24 hours! Even with timely treatment, meningitis can leave severe long-term effects, such as intellectual impairment and hearing loss. It is essential for us to understand and take preventive measures to safeguard our own and our family's health.

Meningitis Symptoms Resembling a Common Cold?

Meningococcal meningitis spreads through respiratory droplets when a person coughs or sneezes, and its symptoms can mimic those of a regular cold. These include high fever, fatigue, headache, muscle soreness, and stiffness. This similarity often leads to confusion, resulting in delayed treatment.

The only distinguishing factor is the rapid progression of meningococcal meningitis, which can lead to symptoms such as confusion, shock, seizures, vomiting, and even death within 24 hours. If parents have any suspicions, seeking immediate medical attention is crucial.

The Most Common Serotype in Hong Kong - Serotype B

Meningococcal meningitis manifests in various serogroups, with a total of thirteen known types. Among them, six are more prevalent: serotypes A, B, C, W, X, and Y. However, the most common serotype in regions like China, Hong Kong, and the United Kingdom is serotype B. It accounts for approximately 50% or more of all cases, and its fatality rate is nearly 50% higher compared to other serotypes.

This year, Hong Kong has already recorded five cases of meningococcal meningitis. It is strongly recommended that parents promptly have their children vaccinated. However, it's important to note that the government does not provide the vaccine for serotype B meningococcal infection. Parents seeking this specific vaccination will need to visit private medical centers.

According to the Centers for Disease Control and Prevention (CDC), administering the MenB vaccine offers effective protection against meningococcal serogroup B infection. Research shows an impressive efficacy rate of 95-100%, providing targeted defense for our children's health.
