Özet:

Legionella pneumophila is a bacterial pneumonia agent ranging from mild pneumonia to severe pneumonia and multi-organ failure, which can cause community and hospital-acquired pneumonia, sporadic or outbreaks. If Legionella pneumophila is not considered and diagnostic tests are not requested, it can be overlooked. Here, we present a case who was admitted to the emergency room with high fever, cough, and shortness of breath during the Covid-19 pandemic and was diagnosed with Legionellosis with Legionella antigen positivity in the urine. In the case, Covid-19 infection was ruled out by the absence of typical involvement in computed tomography and the negative detection of the Covid-19 polymerase chain reaction test. Levofloxacin treatment for Legionella pneumophila was applied to the patient for a period of 21 days. The patient, whose clinical and laboratory findings improved, was discharged. In conclusion, we conclude that Legionella pneumophila pneumonia can be confused with Covid-19 pneumonia during the Covid-19 pandemic period and should be kept in mind in patients whose anamnesis and clinical findings are compatible with legionella.
