Are there bacteria if hotel sheets are laid backwards?

The hotel sheets were laid backwards and there were bacteria. According to relevant public information, most hotels will replace sheets, quilts and other bedding after each guest checks out, and clean and disinfect the beds. However, if cleaning is not thorough or disinfection is not in place, harmful substances such as bacteria and viruses may remain. In addition, if guests eat, smoke, etc. on the bed, it will also increase the risk of bacterial infection from the sheets being spread backwards. Therefore, in order to protect your own health, it is recommended that when checking into a hotel, you should check the cleanliness of sheets, quilts and other bedding, and try to avoid eating, smoking and other behaviors in bed.
