Can bed sheets and towels in star-rated hotels be infected if they are not disinfected?

The sheets and towels in some low-end hotels are dirty. They won't change it as long as it doesn't look dirty. And many guests also use towels, bath towels and so on. Wipe their feet. Only those high-end star-rated hotels are at ease, and every tenant will change disinfection after use. However, personal advice is to try not to use their bath towels. I usually bring my own when I go out. Therefore, the existence of sexual transmission may also infect some skin diseases.
