Spring is the high season for infectious diseases. For infectious diseases, prevention is better than cure, and the spread of most infectious diseases can be prevented with a few simple lifestyle and behavioral changes. 1. Wash your hands regularly: Pathogenic microorganisms can live on the surface of objects for minutes to months. Think about it, these microorganisms live on your computer keyboard, bus handrails, power switches, door handles …… The best way to prevent it is to wash your hands effectively, especially remember to wash your hands before and after going to the bathroom to prevent bringing the virus to your private parts. 2, do not share personal items: toothbrushes, towels, razors, handkerchiefs, nail clippers and toys are hiding places for disease-causing pathogens, especially in family life, try to avoid cross-use. 3. Cover your mouth and nose when coughing or sneezing: As a rule, pathogenic microorganisms begin to grow before they start, and the microdroplets formed in the air by coughing or sneezing spread these pathogens, so when you cough or sneeze, instead of using your hands, use your arms, clothes or elbow and wrist to cover your mouth and nose. 4. Immunization: The immune system has a memory function for previous infections. Immunization produces antibodies to avoid a second infection with the same pathogen. 5.Safe cooking: Microorganisms can grow vigorously in almost all foods, and improper food handling and poor eating habits often cause foodborne illness. 6. Be a smart traveler: Infections can easily occur when traveling, especially in developing countries. Please take care to ensure that you drink safe water sources, as well as immunizations for your travel destination. 7.Safe sex: Sexually transmitted diseases are the easiest to prevent and can usually be prevented through safe sex (including the use of condoms). 8, do not dig nostrils, mouth or rub eyes: digging nose is not only indecent, but also easy to cause the spread of infection. Many microorganisms like warm, moist cavities, such as mucous membrane-covered mouth, eyes. Spring is prone to “red eye”, most of which is caused by rubbing the eyes with unclean hands. 9, be careful of animals: care for animals, but also to realize that animals can spread disease. Pay attention to whether your pet’s immunizations are due? Are you cleaning up the sand and gravel where your pet “lives”? If you are accidentally bitten by dogs, cats, bats, foxes, etc., you should receive rabies vaccination in a timely manner. Finally, pay more attention to news about infectious diseases, such as avian flu in spring, so try to avoid going to the infected areas during your trip to reduce the risk of being infected.
