Unlike the younger generation, the elderly can use the Internet for “cloud socialization” and love to move around during the New Year holidays, which also increases their risk of being exposed to the virus. The following aspects of protection can be done: 1, wearing masks: ordinary cotton masks have no protective effect, it is recommended to give priority to medical surgical masks, followed by medical care masks; 2, travel mode: the elderly travel as far as possible not to choose crowded public transport, it is best to walk, take a taxi or be driven by family members; 3, activity locations: choose less people, well-ventilated places, such as taking a good mask to the park or outdoor. Do not take off your mask even when you see your acquaintances, and it is recommended to keep a distance of more than 1 meter to say hello.
