1) Wash your hands frequently. germs can be found on your keyboard, your light switch, or even on the elevator button! Surprisingly, The Centers for Disease Control and Prevention (CDC) recommends washing thoroughly and vigorously with soap and water for at least 20 seconds, followed by hand-drying with a paper towel. In the absence of running water, an alcohol-based hand gel or wipe will suffice.
2)Don’t share personal items. Toothbrushes, towels, razors, handkerchiefs, and nail clippers etc)
3)Cover your mouth when you cough or sneeze,the current recommendation is to cover your mouth with your arm, sleeve, or crook of the elbow, rather than using your hands.
4)Be a smart traveler. Infectious diseases can easily be picked up while traveling, particularly when traveling to underdeveloped countries. If your travel destination is one where water is questionable, make sure to use a safe water source such as bottled water for drinking and brushing your teeth. Eat foods that have been cooked, and avoid raw vegetables and fruits. Finally, be sure to update all immunizations that are advised or required for your travel destination.
