Pediculus humanus and Phthirus pubis are types of lice that affect humans. Pediculus humanus is commonly known as head lice and primarily infects the scalp, whereas Phthirus pubis, is commonly known as pubic lice because it infests the pubic hair. Both types of lice are small parasitic insects that live close to the human skin sucking and feeding on blood. They can cause itching, redness, and irritation in the affected areas.
Pediculus humanus is most commonly spread through direct head-to-head contact or by sharing combs, and hats, whereas Phthirus pubis is commonly spread through sexual contact, but it can also be spread through close personal contact or by sharing personal items. Treatment for lice typically involves drugs like topical benzyl alcohol to kill the lice, and prevention requires proper body hygiene.
