Shared room communal washing machines are generally not infected with viruses. After washing and drying clothes, it is difficult for viruses to survive. If possible, you can set the water temperature of the washing machine to 60℃-90℃, then dry naturally or dry at high temperature, and pay attention to washing hands after using the public washing machine. For common areas and public items, use 84 disinfectant or alcohol to wipe the surface when necessary. Toothbrushes and towels placed in the bathroom can be put back in their own rooms and taken out again when in use.
