The man's abdomen was itchy, and the doctor took out 17 pubic lice with tweezers! There are 3 routes of transmission of pubic lice
Mr. Liu (pseudonym), 25 years old this year, recently had a problem that made him a little ashamed-his abdomen was extremely itchy every day. It's not easy to scratch directly when you are outside, the whole person is like a hundred claws scratching the heart.
Finally, when the rest day came, he hurried to the hospital for examination. Through the examination, he found that there were many small white dot-like flakes on his abdomen. Under the slit lamp, he could see that they were bugs. After careful comparison, he found that it was Yin Lice and its eggs.
Afterwards, the doctor used microscopic tweezers to remove the pubic lice on his body, and asked Mr. Liu to pluck off the hair on his abdomen and perform anti-inflammatory treatment. The doctor counted the number of pubic lice that had been caught, and found that there were as many as 17 of them!
Mr. Liu was a little surprised when he learned that he had pubic lice. He didn't know where the pubic lice came from. He had never touched any dirty things before, but he just went to his girlfriend's house to spend the night last week.
Afterwards, Mr. Liu blushed and told the doctor that in fact, not only his abdomen was itchy, but his buttocks had also been itchy for a while, but he was always embarrassed to say so.
The doctor advised him to go to the dermatology department for treatment, where he was diagnosed with pubic lice and needed further treatment in the hospital.
1. Why do people seldom get lice nowadays?
In the 1980s and 1990s, lice were rampant, especially in young children, and it was not uncommon for lice to appear. But in recent years, it is rare to hear that someone has been infected with lice. Why is this?
First of all, let's understand where the lice come from. The ancestors of elephants and elephant shrews contracted tiny skin parasites from a bird thousands of years ago, creating an uncomfortable intimacy between mammals and lice, according to an investigation. continues to this day.
Biologists at the University of Illinois at Urbana-Champaign conducted a genomic study of the lice tree in mammals and found that lice in mammals may date back to before the extinction of the non-avian dinosaurs .
Lice have the remarkable ability to switch hosts when they get the chance, and they have switched hosts at least 15 times before their first parasitism on a mammal.
Lice is a wingless parasitic small insect, usually off-white, with an oval body and a little smaller than a sesame seed.
Lice can be divided into three types: head lice, body lice, and pubic lice . Head lice are generally black and gray in color, grow in human hair, and mainly rely on blood sucking for a living; body lice mainly live on underwear, and generally Appears in crevices, creases and waistbands of clothes.
Pubic lice can appear in places with thick and thin body hair, such as the genitals, around the anus, and may also appear on the eyelashes.
Why do people seldom get lice nowadays?
The main reason is that the living standards of modern people have been greatly improved , and people pay more attention to hygiene than early people. In this way, the transmission route of lice will be blocked, and the chance of seeing lice will be much less naturally. Of course, it is not ruled out that some people will be infected with lice, and the transmission rate is still very strong after infection.
2. Why do pubic lice not grow on the head?
Different types of lice grow in different parts. For example, pubic lice do not grow on the scalp. Why?
Pubic lice are parasites that live in the body hair around the private parts and feed off the blood that bites the surrounding skin. Pubic lice are very small in size, and their bodies are about the same length and width, so they need to live in areas with sparser and thicker hairs, and pubic hair is just the right place for them to grow .
However, the hair on our scalp is relatively dense, and it is difficult for pubic lice to survive in this environment, so they will not grow on the scalp.
The appearance of pubic lice is related to many factors, and there are mainly 3 transmission routes:
One is sexual transmission , where either partner has a high risk of pubic lice, and the other partner is also at high risk of infection;
The second is direct contact transmission , such as sharing the same bed with eating and drinking patients, crowded living places/poor environmental conditions, etc.;
The third is indirect contact transmission , such as touching underwear, towels, bed sheets, etc. taken off by patients with pubic lice, infection may occur.
After infestation with pubic lice, the typical symptom is local itching, which is more severe at night . Because pubic lice will suck human blood, in the process, it will stimulate the nerve endings of the skin, and then produce itching. The human body is in a quiet state at night, which is more conducive to the pubic lice to suck blood.
In addition to itching symptoms, pubic lice can also cause symptoms such as green spots, blood scabs, papules, and pustules on the skin, and the symptoms will become more serious after scratching.
When pubic lice are diagnosed, it is necessary to consult a professional doctor for advice and intervene in time. Treatment includes drug treatment, pubic hair removal, etc.
At the same time of treatment, we should also pay attention to keeping the private parts clean. It is recommended to wash them once a day, which is helpful to prevent the appearance of pubic lice.
