TL;DR
"Superspreaders" are people who carry more lice and pass them to more contacts. With head lice, anyone with an active infestation can spread them through head-to-head contact — there's no special "superspreader" type.
What are superspreaders?
In infectious diseases, superspreaders infect disproportionately more people. With head lice, spread depends on head-to-head contact. Children who hug, share pillows, or sit close together are more likely to pass lice. The more lice someone has, the more chances for transfer.
Can superspreading occur with head lice?
Lice crawl from one head to another. They can't jump or fly. Anyone with lice can spread them during close contact. Fix: treat everyone at once, avoid head-to-head until clear. Confirm before treating. See how lice move.
