In addition to pneumonia, it is also important to prevent enterovirus, and the secret is to wear a mask and wash your hands frequently. If two children in a classroom are infected with enterovirus within seven days, the class must be closed according to regulations, which will cause problems for everyone. Therefore, washing hands frequently and properly is the most effective way to prevent the virus. At home, please supervise children to wash their hands with soap, and when they go out, they must follow the five times of washing hands, and they should not bite their fingers; not only children, but also adults should do this! Not only children, but also adults should follow the five steps of "wetting, rubbing, rinsing, holding, and wiping", pay attention to personal hygiene, and carry handkerchiefs and toilet paper, so that the virus can stay away from us.
