Pneumonia prevention focuses on reducing infection risk and strengthening immunity. Vaccination is essential, including pneumococcal and annual influenza vaccines. Good hand hygiene, respiratory etiquette, and avoiding close contact with sick individuals limit transmission. Stop smoking, as tobacco damages lung defenses. Maintain balanced nutrition, adequate sleep, regular exercise, and manage chronic conditions such as diabetes or COPD. For hospitalized or high-risk patients, proper oral care and early mobilization help prevent complications. Use antibiotics only when prescribed to avoid resistance. In healthcare supply discussions, terms like ceftriaxone injection wholesale may arise, but medications should be used judiciously and under medical supervision to prevent pneumonia effectively.
