A74.8: Other chlamydial diseases

Other chlamydial diseases, classified under the ICD-10 code A74.8, refer to infections caused by Chlamydia bacteria other than sexually transmitted Chlamydia trachomatis. These bacteria are microscopic organisms that can live within human cells and cause a variety of diseases. Transmission generally occurs through direct contact with the bacteria, which can be present in secretions from the nose, throat, or eyes of an infected individual. Common symptoms associated with these chlamydial diseases vary based on the type and location of the infection, but may include fever, sore throat, fatigue, and swollen lymph nodes. Certain types of these infections can also result in inflammation of the eyes or lungs. Disease progression is often gradual, with symptoms becoming more severe if left untreated. The respiratory, ocular, and sometimes the genitourinary systems can be primarily affected by these diseases. While certain chlamydial diseases can lead to serious complications, many are treatable with appropriate medical therapy.
