Head lice are found worldwide. In the United States, infestation with head lice is most common among pre-school children attending child care, elementary schoolchildren, and the household members of infested children.
Lice have been parasitizing humans for millions of years and likely dispersed throughout the World with the human migrations out of Africa, so they can be good markers for studying human evolution.
Head Lice in Australia
Head lice (Pediculus Capitis) are a common problem that most parents, students and teachers in Australia are familiar with. They are tiny parasites, about the size of a sesame seed, and live on the human scalp and hair.
Head lice seem to be more common in Caucasian, Hispanic, and Asian American people than in African American people. For example, fewer than 0.5% of African American schoolchildren experience head lice compared with about 10% of schoolchildren of other races.
But what about all of the other hair types? Because Caucasian people get head lice the most, many people think that perhaps lice prefer lighter hair. The truth of the matter is that lice don't care if your hair is thick or thin, straight or curly, blonde or black, they just like hair.
In the United States, infestation with head lice is much less common among African-Americans than among persons of other races. The head louse found most frequently in the United States may have claws that are better adapted for grasping the shape and width of some types of hair but not others.
Adult lice are usually dark brown and about 2 to 3 mm long. Hatchlings (young lice) are often a lighter brown colour and about 1 to 2 mm long. Eggs will be attached to the hair shaft. They can be very tiny and hard to see, especially newly-laid eggs close to the scalp.
Head lice infestations are common, affecting an estimated 6 million to 12 million people each year. Lice are most common among school-age children who are more likely to have close contact with each other or share combs, brushes, hats and other objects that touch the hair.
Girls are more likely to get head lice than boys, possibly because of their play styles and sharing of personal items. People with long or short hair can contract head lice. Although all races can get head lice, studies show that children of African-American descent are less likely to become infested.
You may never know where your case of lice came from, but it started when either a pregnant louse or two live bugs made their way to your human head through head-to-head contact with another human head hosting an active case. If you just have eggs, then there was at one time one pregnant louse on your head.
The oldest physical evidence of head lice on a human was a nit found on the hair of a 10,000-year-old body at an archeological site in Brazil. Lice combs have been found in the tombs of Egyptian royalty, and even Cleopatra was said to have solid gold lice combs buried with her.
All people, no matter their race, ethnicity, gender, or age, are susceptible to getting lice. The only demographic immune to lice are people with no hair! So, when pondering can African Americans get lice, just remember that if a person has hair, then yes, they can get lice.
Yes. Despite popular rumors, black people can get head lice. Head lice are parasitic insects that feed on human blood from the scalp. They are not picky about the color of the scalp and normal hair oils and products commonly used on Black hair aren't enough to prevent or kill them.

Millions of people get infected with pubic lice every year. They are tiny insects that look like tiny versions of the crabs you see at the beach. They live on the skin and coarse hairs that are around your genitals, and they feed on your blood.
As far as we know, there have not been any clinical studies proving any human population to be immune to head lice. However, head lice can have difficultly attaching their eggs to hair that is thick or coarse; therefore, those individuals may be less likely to experience head lice infestation.
Why Do Kids Get Head Lice More than Adults? The answer is pretty straightforward. It's not that the pesky critters prefer children's blood to adult's. It's the simple fact that kids are in closer contact with one another on a daily basis.
How does a head lice infestation occur? Head lice have no wings and do not fly or jump, but they can crawl or run through hair quickly. Most commonly, head lice are spread by direct head-to-head contact with an infested person.
Adult lice can live up to 30 days on a person's body. To live, adult lice need to feed on blood several times daily. Without blood meals, the louse will die within 1 to 2 days off the host.
Washing, soaking, or drying items at a temperature greater than 130°F can kill both head lice and nits. Dry cleaning also kills head lice and nits. Only items that have been in contact with the head of the infested person in the 48 hours before treatment should be considered for cleaning.
Nits take about 1 week to hatch (range 6 to 9 days). Viable eggs are usually located within 6 mm of the scalp. ) and become adults about 7 days after hatching.
Although head lice can feed on different blood types, they cannot thrive on different Rh blood factors. Therefore, lice will only prefer to move to somebody else of the same rhesus factor irrespective of the blood type.
You may be able to see the lice, but they're often hard to spot because they're small, avoid light and move quickly. Lice eggs (nits) on hair shafts. Nits stick to hair shafts and may be hard to see because they're very tiny.
