Legionnaires’ disease is an infection of the lungs, caused by the Legionella bacteria. Most often, Legionnaires’ disease is caused by breathing contaminated droplets of water, which is the result of inadequate water systems. The disease is treated easily with antibiotics, provided that treatment is initiated as early as possible. Legionnaires’ disease is serious and requires medical attention; if you suspect having any symptoms, do not hesitate to contact our doctor. Learn more about the symptoms of Legionnaires’ disease.
Fever is a common symptom of Legionnaires’ disease and occurs as the body works to fight infection. In most cases, mild to moderate fever resolves with hydration and rest. However, if a fever persists or becomes unusually high, consulting a healthcare provider can help determine appropriate care. Symptoms of Legionnaires’ disease typically develop between 2 to 10 days after exposure, though in some cases, they may take up to two weeks to appear.
Chills often accompany fever as the body regulates temperature in response to infection. This sensation occurs due to muscle contractions that generate heat. Keeping warm with blankets and drinking warm fluids may provide relief. Legionella bacteria can lead to two types of illness—Legionnaires’ disease and Pontiac fever—each with varying symptoms. If you experience persistent symptoms, a healthcare provider can help assess the next steps.
A cough is a common symptom of Legionnaires’ disease, as the infection primarily affects the lungs. Coughs can be dry or may produce mucus, varying in severity. If a cough persists or worsens, consulting a healthcare provider can help determine appropriate management. While Legionella bacteria can be present in certain environments, the risk of infection remains low in well-maintained spaces.
As Legionnaires’ disease primarily affects the lungs, individuals may experience symptoms such as mild chest discomfort, coughing, or shortness of breath. While these symptoms can vary, early recognition and treatment can support recovery. Older adults and individuals with certain health conditions may have an increased risk of infection. Seeking medical guidance for persistent symptoms can help ensure appropriate care.
Legionella bacteria are most commonly transmitted through inhaling small droplets of contaminated water in certain environments, such as large buildings with complex water systems. Infection does not occur through drinking water. Symptoms, including headache, typically develop within a few days of exposure and may range from mild to moderate. Most individuals recover well with timely treatment, and early medical care can help reduce the risk of complications.
If you develop Legionnaires’ disease, one of the main symptoms you may experience is soreness, especially in the muscles. Pain or discomfort is most often felt in the joints. Often, a mild headache accompanies muscle pain; this is usually one of the first symptoms to appear. Later, a more aggressive sign may develop, including a high fever. At this stage, muscle pain tends to get worse. To reduce muscle pain, try adding a warm compress over the affected area, and ask your doctor if you may take over the counter pain medication.
Some individuals with Legionnaires’ disease may experience mild chest discomfort due to inflammation in the lungs. While not everyone develops this symptom, it may be more common in certain cases. Seeking medical evaluation for persistent symptoms can help guide effective treatment. Managing the underlying infection is key to supporting lung health and recovery.
Fatigue is the feeling of extreme tiredness and sleepiness that occurs when your body is fighting an infection and uses more energy than usual. Therefore, you feel tired as a result; however, fatigue may or may not go away with rest, and it can persist throughout the infection. If you experience fatigue, it is important to rest so your body can effectively fight the infection. Talk to your doctor about possible treatment options, and how to combat fatigue. If you belong to a risk group, you have a higher right for developing Legionnaires’ disease. Such groups include people over the age of 50, as well as those who have a weak immune system.
Some individuals with Legionnaires’ disease may experience nausea, dizziness, or an upset stomach. These symptoms can vary in intensity and may improve with hydration and rest. Drinking fluids and eating light meals may help alleviate discomfort as the body recovers. If you’re feeling nauseous, lay down and practice deep breathing. This technique will help calm you down and reduce nausea. Sip water and contact your doctor if symptoms persist.
Some people who become infected with Legionnaires’ disease will also demonstrate symptoms that affect the stomach. That’s why in some cases, you may experience diarrhea. The effects of the disease can be harmful to the stomach, and the bacteria can cause a reaction by which your stomach tries to eliminate any bacteria from its interior. The result is diarrhea, which may range from mild to severe. It is essential to stay hydrated because diarrhea often leads to dehydration; also, avoid solid foods if you experience diarrhea, and aim to eat bland liquids such as water, soup, or smoothies.
