1. If the elderly have less serious diseases, they can consult online or go to community hospitals with the help of their families. 2. If the elderly have signs of a cold, it is not recommended to go to the fever clinic immediately, which will increase the risk of infection. You can observe yourself first, reduce going out and avoid direct contact with children. 3. If you must go to the hospital, do a good job of protection and don't move around. Before going to the hospital, family members and the elderly must wear masks. When in the hospital, be careful not to touch the outside of the mask, don't rub your eyes, and wash your hands after taking off the mask. Pay attention to protect others, keep your distance from others, and block them with your elbow when sneezing or coughing.
