Lice Day

June 15th. A day you've probably never heard of, but it affects millions of people around the world. World Head Lice Day is an unofficial but very necessary holiday. Lice are not a sign of dirt or social lowliness. They are parasites that love clean and dirty hair equally, rich and poor, adults and children. Every year, tens of millions of people contract pediculosis, especially children aged 4-12. Shame and misinformation hinder people from starting treatment on time, and doctors are sounding the alarm: lice are becoming resistant to medications. On this day, dermatologists, educators, and parents unite to tell the truth about lice and dispel myths.

Who are lice and where do they come from

Lice are small wingless insects that parasitize on humans. There are three types: head (Pediculus humanus capitis), clothing (Pediculus humanus corporis), and pubic (Phthirus pubis). The head louse lives in hair, feeding on blood every 2-4 hours. Outside the human head, it dies within 1-2 days. The female lays eggs (nits), attaching them to the hair shaft. After 7-10 days, larvae hatch, which become adults in 10 days. The cycle is closed. The source of infection is contact with an infected person (hair to hair). Lice do not jump or fly; they crawl. Therefore, you can become infected by sharing combs, hats, headphones, pillows, as well as in kindergartens, schools, camps. Lice do not carry diseases, but they cause itching, scabs, secondary infections.

The history of lice combat: from combs to chemistry

Lice have accompanied humans for millennia. Combs for combing nits have been found in the tombs of Egyptian pharaohs. In Ancient Greece and Rome, lice were treated with oils and combing. In the Middle Ages, people were shaved bald to get rid of parasites (hence the fashion for short haircuts). In the 19th century, the first insecticides (preparations based on mercury, sulfur) appeared. In the 20th century — DDT (now banned). In the 1980s, permethrin and malathion began to be used. In the 2000s — ivermectin (pills and lotions). Today, the arsenal is vast, but lice are evolving: they develop resistance to permethrin. Therefore, it is necessary to combine methods.

Myths about lice that hinder treatment

Myth 1: lice thrive on dirty people. Truth: clean hair is easier to colonize because nits are harder to attach to dirty hair. Lice love healthy scalp skin. Myth 2: you can catch them from animals. Truth: human lice do not live on cats and dogs. Myth 3: lice carry HIV, typhoid. Truth: the head louse does not carry the causative agents (the clothing louse does, diphtheria). Myth 4: you can get rid of lice by dyeing your hair. Truth: dye contains oxidizers that can kill adult lice, but nits survive. Myth 5: one wash with kerosene is enough. Truth: kerosene is toxic, causes burns, but does not kill lice.

Modern treatment methods

Medications: permethrin (lotion, shampoo, cream) — requires two treatments with an interval of 7-10 days to kill hatched larvae. Malathion (liquid) — acts on nits, but takes a long time to absorb (8-12 hours). Ivermectin (lotion) — effective, but expensive. Spinosad (spray) — a new medication that destroys nits. Physical method: combing nits with a fine comb (metallic, with notches). The combination of chemistry and combing is the gold standard. Folk remedies: applying oil (olive, coconut) at night makes it difficult for lice to breathe, but does not kill nits. Vinegar softens the "glue", but can cause burns.

Specifics in children: what parents need to know

Children aged 4-12 are at risk. They play in close contact, exchange hats, hairpins. When lice are found: do not panic, do not shame the child. Report to the kindergarten or school (so they can check others). Treat all family members (even without symptoms). Wash bedding at 60°C, iron with an iron. Wash soft toys. Combs, hairpins soak in alcohol or boiling water. Do not use pesticides on young children without consulting a doctor. Combing nits every 3 days for 2 weeks.

The problem of resistance and the future of combat

Lice mutate: populations have appeared that are resistant to permethrin, malathion. Combinations must be used (e.g., permethrin + combing). A vaccine is being developed. A new remedy is dimethicone (silicone oil), which physically blocks the breathing holes of lice. Safe for humans. World Head Lice Day calls on scientists and pharmaceutical companies to develop new agents, and parents to reasonable prevention.

Social stigma and psychological aspects

Lice still cause disgust and fear. Parents are afraid that their child will be called a "filthy person." Children may become victims of bullying. Adults are embarrassed to seek medical attention. World Head Lice Day aims to remove this stigma. It's just as much a disease as a cold. No one is to blame. Treat and do not be embarrassed.

How to celebrate June 15th

Check your child's head, yours. If you find any, treat them. Tell friends and neighbors about modern methods. Share information on social media (using the hashtag #LiceDay). Do not hesitate to discuss the problem openly. Donate combs and shampoos to an orphanage or school.

Lice will not disappear, but we can make life with them less tortuous. World Head Lice Day is a reminder: the best weapon is not shame, but knowledge.
