Health officials in the United States are on high alert as a rare and dangerous strain of meningococcal disease is on the rise. This specific strain of Neisseria meningitidis bacteria is causing serious infections with higher fatality rates than usual cases of meningococcal disease.
What is particularly alarming is that these infections are affecting middle-aged adults, a demographic that is not typically associated with meningitis. Normally, meningitis strikes babies, adolescents, and young adults. However, the Virginia Department of Health has reported five deaths from this rare form of meningococcal disease.
Meningococcal disease can lead to meningitis and septicemia, or blood poisoning, and is transmitted through respiratory and throat secretions. In the US, there are four different groups of meningococcal bacteria, with the highest number of cases in 2023 caused by the ST-1466 strain in the Y subgroup.
In 2024, there have already been 143 reported cases, almost 80% more than at the same point in 2023. The majority of cases are among adults aged 30 to 60, Black individuals, and those with HIV. Symptoms of this rare strain can include fever, headache, stiff neck, aversion to light, nausea, and bloodstream infections with symptoms such as fever and chills, vomiting, and a dark purple rash.
Immediate treatment with antibiotics is crucial, as symptoms can quickly become life-threatening. Survivors of this strain may also face long-term effects like deafness or amputations. To prevent bacterial meningitis, there is a vaccine recommended for children aged 11 to 12, with booster shots every 3 to 5 years for vulnerable populations like those with compromised immune systems.
Health officials are urging doctors to be vigilant for any unusual symptoms and to act quickly if they suspect a case of this rare form of meningococcal disease.
