A new school year and another battle between the parasitic parasites and the children they love lives, writes Cameron Webb of the University of Sydney
A new school year and another battle between the bloodshed parasites and the children they love.
But the real losses are stressful parents and caregivers who try to keep their children without lying.
Here are some tips on how to prolong the inevitable challenge of lice treatment as long as possible.
Remind me, what are the head lice?
Lids (Pediculus capitis) are insects found almost exclusively in the hair on human heads. These parasites are not found anywhere else on the planet.
They are perfectly designed to suppress hair up and down, feeding blood from the skin of those infected. He usually feeds about three times a day and spends 15 minutes each day.
While their bite can cause slight irritation, the lice do not distort errors that make us worse.
The whole barrel does not live long – no more than a month. Adults lay an egg (commonly known as nits), which usually affects about a week. This life cycle is simple but essential for the identification and elimination of contamination.
The eggs are tightly sealed into the hair shafts. This egg, even when hatched, remains and grows with hair springs.
This means that staining nits more than a centimeter or so from the scalp may not require treatment at all.
Instead, look at how lively lions are moving. This is the most reliable way to confirm the infestation. For easier searching, use a special caterpillar from local pharmacies.
How are children infected?
They will not jump or fly nor swim the whole head. They move from head to head through direct contact, because the hair stem from two people contacts, creating a bridge for adventurous lice in the new world.
But the lice may be embarrassing, one study showing that the hair must be specifically aligned so that the parasites can jump from one fiber to another.
This is why the spread of lice from one person to another does not happen as fast as urban myths suggest.
Sharing hats, wipes or pillows dramatically does not increase the chances of lice picking. They will not crawl on the floor in the classroom either.
Direct contact "head-to-head" is the best way to share infestation, so watch out for kids full of smartphones and tablets!
Everyone does not necessarily have a special hobby for clean or dirty hair. Short hair is not resistant to infection, but long hair means greater chances of lifting lice.
Ensure that your hair is neatly pulled back will dramatically reduce the risk of having all the head.
In Australia, are real problems in the head lice?
All heads are a problem all over the world. But they are in most cases rather unpleasant than health risks.
Research suggests that about one-third of Australian children in elementary school age may currently have lice in their head. With more than 2.1 million primary school students in Australia, there are about 700,000 potentially infected children.
It is much more difficult to control the whole head than in the past. International studies show that lice become resistant to commonly used insecticides. It is also likely that this will be a problem in Australia, but further research is needed to better understand the situation here.
Alternatives to traditional insecticides, such as botanical extracts, may be more useful in the future.

Most health authorities in Australia recommend avoiding insecticides and instead recommend to moisten their hair (or using a conditioner) and then clean the lice.
The essence of eradication of all beard attacks is two treatments each week apart. This ensures the killing of all adults, then all the remaining eggs remain, but newly hatched lice are killed by a second treatment before having the opportunity to lay another egg.
Perhaps the biggest health problem associated with the whole head is stress and anxiety for parents and caregivers of infected children.
Even before even a single blame occurs, the school alert finding of a "lice outbreak" can be enough to trigger a frantic scratch! There is even a term for this: psychosomatic itching.
Unfortunately, there are no quick fixes to get rid of everything. And no matter what social media claims, using mayonnaise, hair straighteners or household cleaning products) is a bad idea.
The most important thing is to remember that they will not cause health problems, poor household hygiene or quality of care.
