Of course, all departments should be divided, and hospitals without conditions will also be divided, but some special departments must be divided, such as infectious diseases, orthopedics, burns and so on. Because these departments have special circumstances, I won't talk about orthopedics and infectious diseases. There will be people with extensive burns in the burn department, so we need a room with less bacteria. Ordinary patients don't want to see the misery of people with extensive burns. Infectious diseases department is naturally afraid of transmitting infectious diseases to people who are not sick.
