The diagnosis begins with an epidemiologic history, which is traced because it is an infectious disease. Infection is more likely when one has traveled to an infected area or has been in contact with an infected person, or when one has been in contact with a person with fever. Because the diagnosis of any infectious disease requires epidemiologic correlates. The second is whether there are relevant symptoms, because the typical symptoms of C pneumonia are still fever, cough and generalized weakness, and if there are relevant symptoms, it is a very important diagnostic factor for the onset of the disease. There is also nucleic acid testing, but because nucleic acid testing is more dependent on getting the material right, nucleic acid testing needs to be done in the right way if you are going to get exactly the right results. Finally, there’s the CT test, which is a lung CT test that shows images of inflammatory lesions in the lungs and is also very important for diagnosis. So to truly confirm the diagnosis of neococcal pneumonia, a history of epidemiologic exposure, symptoms, and the results of nucleic acid testing and CT are needed. Content source: Dr. Yurai
