Prevention is #1. Here's some tips from Ontario Health.
| Good hand hygiene is the best way to prevent the spread of all flu viruses. Wash your hands with soap and water thoroughly and often. | |
| Keep an alcohol-based hand sanitizer (gel or wipes) handy at work, home and in your car. It needs to be at least 60% alcohol to be effective. | |
| Cover your mouth and nose with a tissue when you cough or sneeze and throw the tissue out. Cough into your upper sleeve if you don't have a tissue. | |
| Avoid large crowds of people where viruses can spread easily. Stay home when you are sick. | |
| Keep common surfaces and items clean and disinfected. |

I've also heard that drinking warm/hot liquids and gargling with salty and warm water are good. I'm giving my kids hot chocolate once or twice per day. I can't see liquids and gargling hurting.
