Protecting yourself from bacterial infections starts with hygiene, vaccination, and healthy habits. Wash hands regularly with soap, avoid touching the face, and cover coughs and sneezes. Keep wounds clean and trimmed, and stay up to date with recommended vaccines. Safe food handling, clean water, and avoiding unpasteurized products reduce exposure. In high-risk settings, wear masks and practice surface disinfection. Seek medical advice for fever, persistent symptoms, or suspected infection.
