Wash your hands frequently. Did you know that microorganisms can live on inert surfaces for several minutes to several months? Imagine that these pathogenic microorganisms can live on computer keyboards, electrical switches and even sidewalks! Surprisingly, most people don't know that effective hand washing is a preventive measure. The Centers for Disease Control and Prevention recommends that you wash your hands thoroughly with soap and water, and then dry them with paper towels. Where there is no running water, alcohol-based gel can meet the requirements of hand washing, although it is not as good as soap and water.
2. Don't * * enjoy personal belongings. Toothbrushes, towels, razors, handkerchiefs and nail clippers are all possible sources of infection (bacteria, viruses and fungi). In kindergarten, children are usually taught to enjoy toys, but learn to control their hands. Try to remember not to share your personal belongings with others.
3. Cover your mouth when coughing and sneezing. In the same spirit, good personal hygiene habits include not only personal cleanliness, but also the traditional practice of covering your mouth when coughing and sneezing. Why is this important when you are not sick? Because for most infections, pathogenic microorganisms begin to grow and divide long before symptoms appear. Coughing or sneezing can spread these bacteria through the air. It is recommended to cover your mouth with your arms and sleeves instead of your hands.
4. Inject flu vaccine. The human immune system is designed to "remember" previous infections. When the body encounters microorganisms that caused infection before, it will increase the production of white blood cells and antibodies to prevent secondary infection. Therefore, by vaccination, we can deceive the body and make it think that it has been infected with a certain microorganism, thus improving its ability to defend against infectious diseases.
5. Use safe cooking methods. Poor food preparation and eating habits are often the causes of food-borne diseases. In fact, microorganisms like all foods, especially those kept at room temperature. Refrigeration can slow down or prevent the growth of most microorganisms. Prepare separate chopping boards for cooked food and raw food, and make sure to wash all fruits and vegetables before eating.
6. Be a smart traveler. It is easy to catch infectious diseases on the road, especially when traveling in underdeveloped areas. If you are in doubt about the water in the tourist destination, please be sure to prepare a safe water source, such as bottled water for drinking and brushing your teeth. Eat cooked food and avoid eating fruits and vegetables raw. It is recommended to update all immunizations according to the tourist destination.
