It is extremely important for you to develop a good personal hygiene habit as the general reoccurrence patients have a low trigeminal system. It is important to wash your hands frequently with hand sanitizer (it is better to use hand sanitizer when washing your hands, because soap has been used for too long), which can also breed bacteria, and wash your hands with running water, and do not use the bottle of hand sanitizer repeatedly). In particular, the skin of patients with chemotherapy or post-transplant reoccurrence is prone to allergies and dryness. Regular application of skin care creams will effectively improve skin quality, and the use of mild neutral baths can also reduce dry skin and dermatitis symptoms. To reduce exposure to bacteria and other pathogens, avoid contact with others, such as hugging. It is also very important to avoid places where you may come into contact with others, especially crowded places such as movie theaters, restaurants during rush hours, crowded elevators, schools, supermarkets, etc. However, this does not mean isolation from the world; it is wiser to be exposed to as few people as possible. In addition, if someone close to you is sick, ask your doctor if the disease is contagious and avoid contact with it for a short period of time until it is not contagious. If complete isolation is not possible, then keep as much distance as possible. It is recommended to stay out of the house as much as possible until the immune function has fully recovered.
