Get StartedPrevention
By Mayo Clinic staffInfectious agents can enter your body through:
- Skin contact
- Inhalation of airborne germs
- Ingestion of contaminated food or water
- Tick or mosquito bites
- Sexual contact
Follow these tips to decrease your risk of infecting yourself or others:
- Wash your hands. This is especially important before and after preparing food, before eating and after using the toilet.
- Get vaccinated. Immunization can drastically reduce your chances of contracting many diseases. Make sure to keep your recommended vaccinations, as well as your children's, up to date.
- Stay home. Don't go to work if you are vomiting, have diarrhea or are running a fever. Don't send your child to school if he or she has these signs and symptoms, either.
- Prepare food safely. Keep counters and other kitchen surfaces clean when preparing meals. In addition, promptly refrigerate leftovers — don't let cooked foods remain at room temperature for extended periods of time.
- Practice safe sex. Use condoms if you or your partner has a history of sexually transmitted diseases or high-risk behavior — or abstain altogether.
- Don't share personal items. Use your own toothbrush, comb and razor blade. Avoid sharing drinking glasses or dining utensils.
- Travel wisely. Don't fly when you're ill. With so many people confined to a small area, you may infect other passengers on the plane. And your trip won't be comfortable, either. Depending on where your travels take you, talk to your doctor about any special immunizations you may need.
