Anthrax meningitis
ICD-10 A22.7 is a billable code used to indicate a diagnosis of anthrax meningitis.
Anthrax meningitis is a severe and rare form of meningitis caused by the bacterium Bacillus anthracis, which is primarily associated with zoonotic infections. This condition arises when anthrax spores enter the central nervous system, often following a systemic infection. The transmission of Bacillus anthracis typically occurs through contact with infected animals or contaminated animal products, such as wool, hides, or meat. Inhalation of spores can also lead to pulmonary anthrax, which may subsequently progress to meningitis. Clinically, patients may present with symptoms such as fever, headache, neck stiffness, altered mental status, and other neurological deficits. Diagnosis is confirmed through cerebrospinal fluid analysis, which may reveal the presence of the bacteria. Given its potential for outbreaks, especially in agricultural settings, public health measures are crucial for monitoring and controlling anthrax exposure. Vaccination of at-risk populations, such as livestock handlers and laboratory workers, is an essential preventive strategy. Prompt recognition and treatment are vital, as anthrax meningitis carries a high mortality rate if not addressed swiftly.
