1. The most common way of getting infected is by touching things in public, so you must wash your hands frequently. The virus can only live on your hands for 5-10 mins, but a lot can happen in those 5-10 mins (you can rub your eyes or pick your nose unwittingly).
2. Aside from washing your hands frequently, you can gargle with Betadine Sore Throat Gargle to eliminate or minimize the germs while they are still in your throat (before dripping down to your lungs).
3. Addition to washing your hands frequently, you can also use a mouthwash to kill or reduce the bacteria that remain in your throat and prevent pneumonia from falling into the lungs.
4. Take extra care and drink plenty of water.
