Pneumonia Explained: Causes, Symptoms, and Prevention Strategies

Pneumonia is an infection that affects one or both lungs, caused primarily by bacteria or viruses. Its infectious nature varies: bacterial and viral forms can spread to others, whereas pneumonia from inhaling harmful fumes is non-contagious. Factors like smoking and heavy alcohol use increase vulnerability. Symptoms may develop quickly or over time, including high fever, cough with colored mucus, chest discomfort, breathlessness, chills, exhaustion, and sweating. In vulnerable groups such as infants and seniors, symptoms might include weakness or confusion.

If not treated promptly, pneumonia can enter the bloodstream, causing sepsis, which hinders oxygen flow and drops blood pressure. Fluid accumulation around the lungs, known as pleural effusion, can also occur. Diagnosis involves physical exams and reviewing medical history, supplemented by imaging tests like chest X-rays, blood analysis, and scans. Mild cases usually recover in two to three weeks, but immunocompromised individuals may take up to eight weeks. Most are treated effectively with oral antibiotics; severe cases might need hospital care and IV medications.

Getting vaccinated against pneumococcus bacteria can help prevent bacterial pneumonia and its complications. Good hygiene practices, avoiding contact with sick people, quitting smoking, and handwashing are important preventive steps to reduce risk.
