Pneumonia is a respiratory infection that can affect people of all ages. However, young children, older adults, and those with weak immune systems are at a higher risk of experiencing severe symptoms. Further, the severity of symptoms can vary depending on factors like the type of pneumonia (bacterial, viral, fungal, or aspiration), the individual’s overall health, and age. Nevertheless, recognizing the following early signs of pneumonia can help one seek timely intervention:

Persistent cough
One of the first and prevalent symptoms of pneumonia is a persistent cough. This is the kind of cough that produces a lot of mucus or phlegm. The sign may begin by causing mild discomfort but can become more severe over time, especially if the immunity is compromised due to disease progression. So, a lingering cough that does not seem to improve or gets worse could be a sign of pneumonia.

Fever
Fever is the body’s core temperature rising as it tries to fight external bacteria and infections to maintain immunity. A high body temperature, typically above 100.4°F (38°C), can indicate an infection caused due to pneumonia. The fever may develop without any warning and worsen within a few hours of first onset. This may be accompanied by chills and sweating at night. Here, it is essential to monitor the body temperature and seek medical care if the fever persists.

Shortness of breath
Pneumonia causes inflammation of the air sacs in the lungs, and this affects the function of the organ. As a result, one might experience difficulty breathing or sharp bouts of shortness of breath. Here, it may feel like the airway is being restricted even during rest or with minimal physical activity. Shortness of breath is concerning if it worsens with activity or leads to rapid breathing after physical exertion.

Chest pain
Pneumonia can also cause mild to moderate chest pain that is often accompanied by a feeling of tightness in the chest. The discomfort is often described as sharp or stabbing pain and may worsen when taking deep breaths or coughing. Chest pain can sometimes be confused with heart-related issues, so it is crucial to get examined if one experiences this symptom.

Fatigue
Feeling extremely tired or fatigued is another sign of pneumonia. The infection puts stress on the body, and the immune system works hard to fight it. This can leave one feeling exhausted, weak, and devoid of energy. If one notices unusual and prolonged fatigue, it could be a cause for concern.

Changes in phlegm
While coughing up phlegm or mucus, one should pay attention to its color and consistency. With pneumonia, the mucus may turn yellow, green, or even bloody. These changes can indicate an infection in the lower respiratory tract and should be examined by a healthcare professional.

Any of these symptoms should not be ignored. One should consult a doctor and seek timely treatment upon noticing these signs.
