The use of cloth masks to cover the mouth and nose is now being recommended by Jersey's top medical advisor.
The Medical Officer of Health, Dr Ivan Muscat, has issued updated advice in response to growing expert support for the use of masks when out in public.
The World Health Organization (WHO) has recently come out in favour of mask-wearing as a measure of infection control.
Dr Muscat says cloth face masks should be changed if they become soiled, wet or uncomfortable. Essential workers may need several masks a day to ensure good hygiene and comfort. And people wearing a mask should wash their hands after removing it.
People must still keep a two metre distance from others when they are out and about.
The government is now allowing shops that sell fabric and sewing supplies to open, so islanders can buy the equipment to make their own face masks.
