Although there is no vaccine to prevent the common cold, you can take steps to prevent the spread of the virus that causes it:

• Wash hands clean. Always wash your hands frequently and properly with soap and water. At the same time, you also need to talk to young children about the importance of hand washing and teach them how to wash their hands. If soap and water are not available, use alcohol-based hand sanitizers.
• Disinfect furniture. Always clean kitchen and bathroom countertops with disinfectants and disinfectants, especially when someone in the family has a cold. In addition, children's toys also need to be cleaned periodically.
• Use paper towels. Cough and sneeze into disposable tissues and dispose of them in the trash after use. Then, remember to wash your hands carefully. If a tissue isn't available, learn to cough or sneeze into your elbow instead of covering your mouth with your hand.
• Do not share utensils. Do not share drinking glasses or personal utensils with family members, especially with someone who has a cold.
• Take care of yourself. Eating well, exercising, getting enough sleep, and managing stress can all help prevent colds.
• Don't go to crowded places during a cold or flu outbreak.
