Pneumonia is a common respiratory infection that can affect people of all ages, causing various symptoms that vary in severity. At the same time, many are familiar with the hallmark signs such as fever and cough, shortness of breath, chest pain, and numerous other indicators that can point to pneumonia. This comprehensive article thoroughly explores pneumonia’s signs and symptoms, helping individuals recognize the condition early and seek appropriate medical care. Fever Fever is one of the most prevalent symptoms of pneumonia. It typically presents with a high body temperature, often exceeding 100.4°F (38°C). Fever is the body’s natural response to infection and signifies that the immune system is actively fighting the pneumonia-causing pathogens. Cough A persistent cough is another hallmark symptom. It can produce different types of mucus, including yellow, green, or bloody. The cough may be accompanied by chest pain or discomfort ranging from mild to severe. Shortness of breath Many individuals with pneumonia experience shortness of breath, particularly when engaging in physical activities. This symptom occurs due to the inflammation and infection within the lungs, making it challenging for the respiratory system to function optimally. Chest pain Chest pain is often described as a sharp or stabbing sensation typically felt on the side of the affected lung.
