United States: The cases linked to bacterial infection, which is known to be serious, fatal and even rare, have been spreading across the United States. It is to be noted that the sudden spread of the bacteria has raised concerns of the health authorities and experts. Recently, the federal health agency has warned the doctors and physicians about the increase of the infections.

Health authorities have issued a cautionary advisory to physicians to remain vigilant for specific varieties of uncommon yet severe meningococcal infections that are experiencing an upward trend in occurrence within the United States, according to reports by CNN.

The US Centers for Disease Control and Prevention (CDC) conveyed in a recent health advisory that these infections, stemming from a distinct strain of Neisseria meningitidis bacteria, may manifest with atypical symptoms. Notably, in cases documented thus far this year, approximately one out of every six individuals has succumbed to the illness, representing a heightened mortality rate compared to the usual incidence of meningococcal infections.

These instances are also anomalous in that they are afflicting individuals in the middle age bracket. Traditionally, meningitis infections primarily affect infants or adolescents and young adults.

The issuance of the CDC’s alert follows a prior caution from the Virginia Department of Health regarding five fatalities attributed to the same uncommon and severe form of meningococcal disease in September.

Meningococcal disease encompasses any ailment induced by Neisseria meningitidis. The infection can precipitate both meningitis and a grave bloodstream infection termed septicemia or blood poisoning.

Transmission of the bacteria occurs through person-to-person contact involving the exchange of respiratory and throat secretions, typically facilitated by activities such as kissing, coughing, sneezing, or residing in close proximity to infected individuals, CNN reported.

There exist four distinct groups of meningococcal bacteria known to circulate within the United States — B, C, W, and Y. According to the CDC, in 2023, 422 reported cases of disease attributed to these bacteria in the United States, marking the highest tally since 2014. Predominantly, these cases were instigated by a specific strain, ST-1466, belonging to the Y subgroup.

Thus far, the year 2024 is on course to surpass that figure, with 143 reported cases in the United States to date — an increase of nearly 80% compared to the corresponding period in 2023.

The CDC notes that the majority of individuals diagnosed with this particular strain fall within the age range of 30 to 60. A disproportionate percentage of cases, totaling 63%, are observed among individuals of Black ethnicity, with 15% affecting individuals living with HIV.

Typical manifestations of meningitis infections encompass fever, cephalalgia, nuchal rigidity, photophobia, and emesis. However, many of the recently documented cases deviate from these typical symptoms. Approximately two-thirds of patients exhibit bloodstream infections, while around 4% present with agonizing, inflamed joints.

Symptoms of meningococcal bloodstream infections include pyrexia and rigors, lethargy, emesis, frigid extremities, tachypnea, diarrhea, and, in advanced stages, a purplish rash.

Initial symptoms may mimic those of various other infections, yet they deteriorate rapidly and can escalate to life-threatening levels within hours, as per the CDC. Prompt initiation of antibiotic therapy is imperative. Survivors may endure enduring repercussions such as sensorineural hearing loss or extremity amputations, according to reports by CNN.

A vaccine offering protection against bacterial meningitis is available. It is recommended for individuals aged 11 to 12, with a booster typically administered at age 16 due to waning immunity. Moreover, it is advised for individuals with specific medical conditions compromising immune function, such as HIV. The CDC recommends individuals in vulnerable demographics receive booster vaccinations every 3 to 5 years.
