ICD-11 code 1A07 refers to typhoid fever, a potentially severe and life-threatening bacterial infection caused by Salmonella typhi. This condition is primarily transmitted through contaminated food and water sources, particularly in areas with poor sanitation and hygiene practices.
Typhoid fever typically presents with symptoms such as prolonged fever, abdominal pain, weakness, and headache. In some cases, patients may also experience other gastrointestinal symptoms such as diarrhea or constipation.
Diagnosis of typhoid fever is often confirmed through blood cultures, where the causative bacteria can be detected. Treatment usually involves antibiotics, and early intervention is crucial to prevent complications and reduce the risk of transmission to others.

#️⃣ Coding Considerations
For the ICD-11 code 1A07, which corresponds to Typhoid fever, the equivalent SNOMED CT code is 87628006. This SNOMED CT code specifically refers to the condition of Typhoid fever and allows for comprehensive and standardized documentation of this particular diagnosis. Healthcare providers can use this code to accurately communicate, track, and analyze cases of Typhoid fever, ensuring consistency and precision in medical coding and record-keeping processes. By utilizing the SNOMED CT code 87628006 for Typhoid fever, healthcare professionals can streamline data management and enhance interoperability between different healthcare systems and settings. This standardized coding system facilitates efficient information exchange and supports quality care delivery for patients diagnosed with Typhoid fever.
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 typhoid fever typically appear between one and three weeks after exposure to the bacteria. The onset of symptoms is often insidious, with patients initially experiencing a gradual onset of fever, weakness, headache, and malaise. Fever is a hallmark feature of typhoid fever, typically spiking to as high as 104°F (40°C) and persisting for several weeks.
As the illness progresses, patients may develop abdominal pain, constipation, or diarrhea. The diarrhea in typhoid fever is often described as “pea soup” or “currant jelly” in appearance and may be accompanied by a distended abdomen. Some individuals may also experience nausea, vomiting, and a decreased appetite, leading to unintentional weight loss.
Additional symptoms of typhoid fever can include a rash of rose-colored spots on the chest or abdomen, which are more common in children than adults. In severe cases, complications such as intestinal bleeding, delirium, and shock may occur. It is important for individuals experiencing these symptoms to seek medical attention promptly for proper diagnosis and treatment.
🩺 Diagnosis
Diagnosis of typhoid fever can be challenging due to its nonspecific symptoms. Clinical diagnosis is often based on a combination of symptoms, medical history, and knowledge of recent travel to endemic areas. However, laboratory tests are crucial for confirmation.
Blood cultures are the gold standard for diagnosing typhoid fever. The isolation of Salmonella typhi from blood samples confirms the diagnosis. However, blood culture results may take several days to return, leading to a delay in treatment initiation.
Additional tests such as stool cultures, urine cultures, and bone marrow cultures can also be performed to increase the likelihood of confirming a diagnosis. These tests help identify the presence of Salmonella typhi outside of the bloodstream, aiding in a more comprehensive diagnosis. Blood tests may also reveal elevated levels of specific antibodies associated with typhoid fever, further supporting the diagnosis.
💊 Treatment & Recovery
Treatment for typhoid fever typically involves antibiotics to kill the Salmonella typhi bacteria causing the infection. Commonly prescribed antibiotics include ciprofloxacin or ceftriaxone. Supportive care such as fluids, rest, and a healthy diet are also important in helping the body fight off the infection. In severe cases, hospitalization may be necessary for close monitoring and intravenous antibiotic treatment.
Recovery from typhoid fever can be a slow process, as it may take several weeks for symptoms to fully resolve. Patients must complete the full course of antibiotics prescribed by their healthcare provider to ensure the infection is completely cleared from their system. Rest and a nutritious diet are essential during the recovery period to help the body regain strength and energy. Follow-up appointments with a healthcare provider may be necessary to monitor progress and ensure there are no lingering complications from the infection.
In some cases, complications such as intestinal perforation or infections in other organs may occur with typhoid fever. These complications will require additional treatment, such as surgery or specific medications, to address the issue. It is important for patients to seek medical attention promptly if they experience symptoms such as severe abdominal pain, persistent vomiting, or changes in mental status. Overall, with proper treatment and care, most individuals with typhoid fever can recover fully and resume their normal activities.
🌎 Prevalence & Risk
In the United States, typhoid fever is a relatively rare disease with typically fewer than 400 cases reported annually. The majority of these cases are actually acquired during international travel to regions with poor sanitation.
In Europe, the prevalence of typhoid fever is also low, with most cases being related to travel to endemic regions. Despite improvements in sanitation in many European countries, sporadic outbreaks of typhoid fever can still occur.
In Asia, typhoid fever remains a significant public health concern, particularly in countries with poor sanitation and limited access to clean water. The disease is more endemic in this region, leading to a higher number of cases compared to the United States and Europe.
In Africa, typhoid fever is widely prevalent, with millions of cases reported annually. The disease burden is particularly high in areas with poor sanitation and limited access to clean water sources. Efforts to control and prevent typhoid fever in Africa are ongoing, with initiatives focused on improving sanitation and access to clean water.
😷 Prevention
To prevent Typhoid fever (1A07), individuals are advised to practice good hygiene and sanitation habits. This includes washing hands thoroughly with soap and water before preparing or eating food, as well as after using the restroom. Proper food handling and cooking methods, such as thorough cooking of meat and fish, can also help prevent the transmission of the disease.
Another important preventive measure is to avoid consuming contaminated food or water. It is recommended to drink only bottled or boiled water, especially in areas where typhoid fever is prevalent. Avoiding raw or undercooked food, as well as fruits and vegetables that may have been washed in contaminated water, can also reduce the risk of contracting the disease.
Travelers to areas with high rates of typhoid fever should consider getting vaccinated against the disease. The typhoid vaccine can provide protection and reduce the risk of infection. In addition, individuals should be cautious about their surroundings and avoid exposure to potential sources of contamination. By taking these preventive measures, the incidence of typhoid fever can be significantly reduced.
🦠 Similar Diseases
