Pneumonia is a lung infection that affects the alveoli, the small air sacs in the lungs where oxygen and carbon dioxide are exchanged. This infection can be caused by a variety of pathogens, including bacteria, viruses, and fungi. Inflammation and filling of the air sacs with fluid or pus can cause symptoms such as fever, coughing up phlegm, shortness of breath, and chest pain.
Although anyone can get pneumonia, certain groups are more susceptible. In addition to children and the elderly, those with weakened immune systems, those with chronic diseases such as diabetes or asthma, and those who smoke are also at higher risk. Exposure to certain settings, such as hospitals or long-term care facilities, also increases susceptibility.

Symptoms, Diagnosis and Treatment
When pneumonia is suspected, the first step is to perform a physical examination and listen to the patient’s chest sounds. Imaging tests such as X-rays are crucial to confirm the presence of infection. In addition, blood tests or sputum cultures can help identify pathogens.
Treatment will depend on the underlying cause. If it is bacterial, antibiotics are prescribed. If viral, it will focus on relieving symptoms while the body fights the virus. Even if you feel better, it is important to follow your medical instructions and complete your medication cycle to prevent complications or resistance.
Prevention: The Key to Fighting Pneumonia
Prevention remains the most powerful weapon against pneumonia. Some preventive measures include:
Vaccinations: Some vaccines can protect against certain types of bacterial and viral pneumonia. Timely vaccination of high-risk groups is crucial.
Hygiene: Washing your hands regularly with soap and water can reduce the risk of infection. It is also important to practice good respiratory hygiene and cover your coughs or sneezes.
A healthy lifestyle: Eating a balanced diet, exercising regularly, getting enough rest, and avoiding smoking can strengthen your immune system and reduce your risk of pneumonia.
