Avoid close contact
Influenza virus can rapidly spread and could make you sick quickly. Therefore avoid getting too close to sick people. Keep your distance from other people when you are sick to prevent them from getting sick as well.
Wash your hands
Cleaning up your hands frequently will assist with shielding you from microbes. An alcohol-based hand sanitizer can be used if the soap and water are not available.
Follow healthy diet
It is certain that proper nutrition provides not only weight control but also immune control of the body. By avoiding harmful food and fast food and eating healthy, you can protect yourself from possible diseases such as flu by increasing your immunity. You should also drink plenty of water throughout the day.
Take care of your body temperature
When it's below 40°F (5°C), you have to take care of your body temperature. If you do not wear appropriately in the cold seasons, you could reduce the strength of your immune system. Therefore, pick out appropriate clothes.
