While the “selfie” craze makes waves around the world, experts warn that physical contact in group photos may lead to an increase in the spread of head lice.
Head lice are small, wingless parasites which live on human hair and feed on blood drawn from the scalp, causing itching and sometimes infection. Infestation is most frequent in children and teens and is spread through head-to-head contact as well as through sharing hats, towels, brushes and pillows, says pharmacist, Giulia Criscuolo.
Health experts warn that children and teens may be spreading head lice by snapping selfies with friends, particularly when there is physical contact during an outbreak. Other technology such as iPads, tablets and video games are also characterized by close physical contact which may also contribute to the spread of head lice.
Criscuolo says children should be cautious of head-to-head contact during back-to-school time. “Children often sit close together, sometimes touching heads when using new technology or taking group selfies. They need to be aware that this may contribute to the spread of lice, particularly during an outbreak.”
