ICD-11 code 1D01.2 corresponds to parasitic or protozoal meningitis, which is a type of meningitis caused by parasitic or protozoal infection within the central nervous system. Meningitis is characterized by inflammation of the protective membranes covering the brain and spinal cord, and parasitic/protozoal meningitis specifically refers to cases where the inflammation is caused by parasites or protozoa. These pathogens are typically transmitted through contaminated food or water sources, or through contact with infected animals.
Parasitic/protozoal meningitis can manifest with symptoms typical of meningitis, such as headache, fever, neck stiffness, and altered mental status. In some cases, patients may also experience seizures, sensitivity to light, and nausea/vomiting. Prompt diagnosis and treatment of parasitic/protozoal meningitis are crucial to prevent serious complications and reduce the risk of long-term neurological damage.
The treatment for parasitic/protozoal meningitis typically involves antiparasitic or antiprotozoal medications to eliminate the infection causing the inflammation in the central nervous system. Supportive care, such as pain management and hydration, may also be necessary to help patients recover from the illness. Prevention strategies, such as practicing good hygiene, avoiding contaminated water sources, and taking appropriate precautions when traveling to regions with a high risk of parasitic/protozoal infections, can help reduce the risk of contracting this type of meningitis.

The use of SNOMED CT also facilitates interoperability and data exchange between different healthcare systems and organizations, ensuring seamless continuity of care for individuals with this particular form of meningitis.
In the United States, ICD-11 is not yet in use. The U.S. is currently using ICD-10-CM (Clinical Modification), which has been adapted from the WHO’s ICD-10 to better suit the American healthcare system’s requirements for billing and clinical purposes. The Centers for Medicare and Medicaid Services (CMS) have not yet set a specific date for the transition to ICD-11.
The situation in Europe varies by country. Some European nations are considering the adoption of ICD-11 or are in various stages of planning and pilot studies. However, as with the U.S., full implementation may take several years due to similar requirements for system updates and training.
🔎 Symptoms
Symptoms of 1D01.2 (Parasitic or protozoal meningitis) typically present similarly to other forms of meningitis. Patients may experience fever, headache, and stiff neck, along with nausea, vomiting, sensitivity to light, and altered mental status. These symptoms can progress rapidly and may lead to neurological complications if not promptly diagnosed and treated.
In cases of parasitic or protozoal meningitis, symptoms can also be accompanied by additional signs such as confusion, seizures, and focal neurological deficits. Patients may exhibit altered consciousness, including coma, as the infection affects the brain and spinal cord. The specific symptoms can vary depending on the causative organism responsible for the meningitis, such as Naegleria fowleri or Toxoplasma gondii.
Given the potentially severe nature of parasitic or protozoal meningitis, prompt medical attention is crucial. It is essential to consider the possibility of parasitic or protozoal causes in patients with meningitis symptoms who have a history of travel to or residence in regions where these pathogens are endemic. Diagnostic tests, including cerebrospinal fluid analysis and imaging studies, can help confirm the presence of parasitic or protozoal organisms in the central nervous system and guide appropriate treatment. Early recognition and intervention are essential in improving outcomes for patients with this type of meningitis.
🩺 Diagnosis
Diagnosis of Parasitic or Protozoal Meningitis, represented by the code 1D01.2 in the International Classification of Diseases (ICD), typically involves a combination of clinical evaluation, laboratory testing, and imaging studies. Given the diverse range of pathogens that can cause meningitis, a thorough assessment of the patient’s medical history and symptoms is crucial in narrowing down potential etiologies. Patients with parasitic or protozoal meningitis may present with symptoms such as fever, headache, stiff neck, altered mental status, and seizures.
Laboratory testing plays a key role in confirming the diagnosis of parasitic or protozoal meningitis. Cerebrospinal fluid (CSF) analysis is often performed through a lumbar puncture to determine the presence of abnormal cell counts, glucose levels, and protein levels. Additionally, CSF samples may be subjected to microbiological testing, including gram stain, culture, and polymerase chain reaction (PCR) assays, to identify specific pathogens such as parasites or protozoa. Blood tests may also be conducted to detect antibodies or antigens related to certain parasitic or protozoal infections.
Imaging studies, such as computed tomography (CT) or magnetic resonance imaging (MRI) of the brain, may be utilized to assess for signs of inflammation, swelling, or other abnormalities that could be indicative of parasitic or protozoal meningitis. However, these imaging modalities are primarily used to rule out other potential causes of meningitis, rather than as definitive diagnostic tools for parasitic or protozoal infections. In cases where clinical suspicion remains high but initial diagnostic tests are inconclusive, repeat lumbar punctures or additional CSF analyses may be necessary to confirm the presence of parasitic or protozoal pathogens in the central nervous system.
💊 Treatment & Recovery
Treatment for 1D01.2, parasitic or protozoal meningitis, typically involves a combination of antiparasitic medications, such as antifungal drugs, antimalarial medications, or antibiotics, depending on the specific infecting pathogen. These medications aim to eradicate the parasites or protozoa causing the infection in the central nervous system. Additionally, patients may receive supportive care, such as pain management, antipyretics to reduce fever, and anti-inflammatory drugs to alleviate brain swelling.
In severe cases of parasitic or protozoal meningitis, patients may require hospitalization for close monitoring and intensive treatment. Intravenous administration of medications may be necessary to ensure rapid and effective delivery of therapy. In some instances, surgery may be required to drain any fluid buildup in the brain or alleviate pressure on the central nervous system caused by the infection.
Recovery from parasitic or protozoal meningitis can vary depending on the specific pathogen involved, the severity of the infection, and the promptness of treatment. Some individuals may experience long-term neurological complications, such as cognitive deficits or motor impairments, despite successful treatment. Follow-up care, including regular medical evaluations and rehabilitation therapy, may be necessary to address any lingering effects of the infection and optimize recovery. A multidisciplinary approach involving medical specialists, physical therapists, and mental health professionals may be beneficial in supporting the patient’s overall well-being during the recovery process.
🌎 Prevalence & Risk
1D01.2, also known as parasitic or protozoal meningitis, is a rare form of meningitis caused by parasites or protozoa. The prevalence of this condition varies across different regions of the world, with some areas experiencing higher rates of infection than others. In the United States, cases of parasitic or protozoal meningitis are relatively rare compared to other forms of meningitis. Due to improvements in sanitation and access to healthcare, the incidence of this condition is low in the US.
In Europe, the prevalence of parasitic or protozoal meningitis is also relatively low. This can be attributed to strict public health measures, such as regular monitoring of water quality and control of insect vectors that can transmit parasitic infections. The overall risk of contracting this type of meningitis in Europe is considered to be low, although sporadic cases may still occur in certain regions.
In Asia, the prevalence of parasitic or protozoal meningitis can vary widely depending on the specific country or region. In some parts of Asia where parasitic infections are more common, the risk of developing parasitic meningitis may be higher. Factors such as poor sanitation, lack of access to clean water, and inadequate healthcare infrastructure can contribute to the incidence of parasitic or protozoal meningitis in certain Asian countries.
In Africa, parasitic or protozoal meningitis is more prevalent compared to other regions of the world.

The lack of access to healthcare and limited resources for disease prevention and control also contribute to the prevalence of parasitic or protozoal meningitis in Africa.
😷 Prevention
To prevent 1D01.2 (Parasitic or protozoal meningitis), it is crucial to take specific precautions against the organisms that cause this type of meningitis. One common organism that can cause parasitic meningitis is Naegleria fowleri, found in warm freshwater environments such as lakes, ponds, and hot springs. To prevent infection with Naegleria fowleri, individuals should avoid swimming or diving in warm freshwater bodies, especially in areas where the amoeba is known to be present.
Another type of parasitic meningitis is caused by the parasite Angiostrongylus cantonensis, commonly known as the rat lungworm. This parasite is typically found in rats, but can also infect snails, slugs, and other animals. To prevent infection with Angiostrongylus cantonensis, individuals should avoid consuming raw or undercooked snails or slugs, as well as wash vegetables thoroughly before consuming them. Additionally, it is essential to wash hands thoroughly after handling snails, slugs, or other potential carriers of the parasite.
Protozoal meningitis can be caused by organisms such as Cryptosporidium, Toxoplasma gondii, and Trypanosoma cruzi. To prevent infection with Cryptosporidium, individuals should avoid drinking untreated or contaminated water, as well as practice good hygiene, especially after coming into contact with potentially contaminated surfaces. To prevent infection with Toxoplasma gondii, pregnant women should avoid changing cat litter boxes, as the parasite can be transmitted through cat feces. Additionally, individuals should thoroughly wash fruits and vegetables before consuming them, as Toxoplasma gondii can be present in soil.
