During an outbreak, you can dry your quilt when the sun is out without fear of contamination. The survival time of novel coronaviruses in vitro is influenced by a combination of dryness, heat, ventilation and UV light. The activity and survival time of the virus are reduced in sunlight. However, it is not recommended to dry the bedding in public areas, when the risk of infection may be increased if an infected person carrying the virus passes by or if droplets with the virus get on the bedding. It is recommended that you dry them on your own balcony, taking care to maintain ventilation. If you do not have the conditions to dry the bedding at home, you can choose to buy an ultraviolet lamp and disinfect the bedding according to the operating instructions.
