The American Academy of Pediatrics has recently updated it's guidelines on head lice in schools.

The AAP indicates that head lice screening  programs in schools have not been proven to be particularly effective with a minimum impact on the incidence of head lice in schools. In addition, these programs are not value for money, and may stigmatize children suspected of having head lice. 

A new study has examined the genetic diversity of head and body lice collected from Bobigny, which is located near Paris (France), and confirmed for the first time the presence of clade E head lice in France. Clade E has upto this point been found mainly in lice from West Africa.

A new study has evaluated the response of head lice to volatiles that emanate from the human scalp, identifying the volatile components of the odor and the attractive or repellent activity of their pure main components.

A new study has assessed the in vitro efficacy of five essential oils against adults of Pediculus humanus capitis using a contact filter paper toxicity bioassay and revealed that Clove oil diluted either in coco oil or sunflower oil demonstrated the best adulticidal activity reaching over 90% within 2 hours in lice submitted to a 30 minute contact.

A new study has conclusively established for the first time that both head and body lice reproduce through paternal genome elimination (PGE), an unusual genetic system in which males transmit only their maternally derived chromosomes.
