that skin infestations such as pubic lice, scabies and ringworm are not only caught through sexual contact but can be transmitted on towels and bed linen? Pubic lice or crabs can survive up to 24 hours away from human skin. Scabies and ringworm can also be caught from inanimate objects, according to Sister Lesley Hunter at St John's Dermatology Centre, St Thomas' Hospital, London: "Ringworm is easily caught in damp, wet places, such as swimming pools and changing rooms, and scabies, although it is mostly transmitted through skin-to-skin contact, can be caught from bedding and clothing." She advises against sharing brushes, combs and towels, too. Prompt treatment is essential, so go to your GP if you suspect that you're infected.
