- Skin Breaks: Bacteria (like Staph) entering through cuts, scrapes, or even bug bites.
- Poor Hand Hygiene: Touching contaminated surfaces and then touching your eyes, nose, or mouth.
- Contaminated Food: Eating undercooked meat or produce washed in “dirty” water (E. coli, Salmonella).
- Airborne Droplets: Inhaling bacteria from a nearby person’s cough or sneeze (Strep, Tuberculosis).
- Weakened Immune System: Being in a “run-down” state makes it easier for opportunistic bacteria to take hold.
- Unsafe Water: Drinking from or swimming in water containing bacteria like Legionella or Shigella.
- Shared Personal Items: Swapping razors, towels, or toothbrushes with someone who has an active infection.
- Secondary Infection: Getting a bacterial infection (like pneumonia) after your body is weakened by a virus (like the flu).
- Improper Wound Care: Failing to clean and cover a wound, allowing “biofilms” to form and fester.
- Vector Bites: Ticks or fleas carrying bacteria (like the ones that cause Lyme Disease) into your bloodstream.
