exp. Dr. Bengisu Ay made statements about Legionnaires’ disease, which is frequently seen in the summer months. Ay, noting that the risk of legionella increases in sanitary installations and air conditioners that are not cleaned, “The bacteria that cause the disease were revealed in 1977 during the Legionnaires’ meeting in Philadelphia, and therefore it was named legionella. Legionella bacteria, which are the causative agents of Legionnaires’ disease, are found in natural water sources and in man-made water distribution systems. If the necessary maintenance and disinfection process is not applied in systems such as plumbing and air conditioning systems, an environment where bacteria can grow will be provided.


Pointing out that the disease is more common in summer, it is also known as summer pneumonia and air-conditioning disease. Dr. Bengisu Ay continued as follows:

“It may be a factor in pneumonia developing in hospitalized patients. Therefore, hospital air conditioning and sanitary systems are regularly checked for Legionella at certain intervals. The way of transmission can be through the entry of contaminated water into our respiratory system or direct contact with this bacteria. Smokers, those with chronic lung disease, cortisone use, surgical interventions and organ transplant patients are at risk.

The most common clinical picture is pneumonia. It starts with cough and fever after an incubation period of about 2 weeks. It can cause muscle pain and headache, loss of appetite. It can cause respiratory failure and organ failure. It is treated with antibiotics. Another clinical picture that is not pneumonia is a common cold-like condition called Pontiac fever. It often gets better on its own without the need for treatment. It can cause heart, skin and kidney infections much less frequently.”
