Some time ago, Xiao Wang went on a tour with the tour group and stayed in the collective room booked by the tour group. When he returned from the tour, Xiao Wang always felt a rush of itching from his lower body.
After a few days, Xiao Wang really couldn't stand it, and could only come to the hospital for examination. Through dermoscopy, it was found that the roots of Xiao Wang's lower body hair had a milky yellow "small dot". The doctor told Xiao Wang that these small dots were actually a kind of bug called "pubic lice", and it was precisely because of the "pubic lice disease" that caused him to have continuous itching symptoms.
What is a "lice" and why does it parasitize there?
The so-called pubic lice is actually a small parasite, with a body length of about 2 mm, because it is too small and resembles a flat circle of crabs, also known as crab lice.
Pubic lice mainly bite human skin, eat surface dust, dead skin, and superficial blood for food, if the pubic lice parasitize in a large area, resulting in discomfort or even serious lesions in the skin, it will form a "pubic lice disease".
The reason why this small bug will parasitize "there", on the one hand, because the skin of the private parts is thin, and the diet can easily penetrate and obtain food;
On the other hand, because of privacy and closure, bacteria there multiply and thrive with the help of hair. If the usual cleaning is not thorough, or if you are exposed to the source of infection, it is easy to lead to the breeding of pubic lice, thus inducing "pubic lice disease".
Do not underestimate this disease, although it seems that the symptoms are not very serious, but because the lower body nerves are sensitive, the pubic lice will cause irritation to the nerves in the process of activity, resulting in a "strange itch unbearable" situation, and even inflammatory infections in severe cases.
According to the CDC, more than 2 million people are infected with pubic lice every year, and the number is growing.
Why are more and more people infected with pubic lice? 2 reasons to be vigilant
(1) More and more people live in hotels and inns
With the development of tourism, people are spending more and more time and distances. Away from home, naturally there is a need to stay in a hotel.
And the more people live in the hotel, the more likely there is a source of pubic lice infection. If the store does not pay attention to the cleanliness of towels and bedding, and customers use it without their knowledge, they are more likely to be infected with pubic lice.
(2) Young people's thinking is becoming more avant-garde and open.ed
Compared with the past, today's young people can learn more about the Internet and meet more friends, so their concepts will be more open than those of middle-aged and elderly people.
In contrast, young people also make more friends and fall in love before they get married. While it is good to be open-minded, it will also invisibly increase the transmission route of pubic lice, which will lead to an increase in the number of people suffering from the disease.
Therefore, if you want to prevent pubic lice disease, from the above two reasons, reducing the contact of the source of infection is a more effective way. The source of infection of pubic lice disease mainly includes three types of pet contact, sexual contact and contact with objects.
In daily life, before contacting pets, objects and even partners, try to do a good job of examination to rule out the possibility of infection, so as to effectively reduce the risk of pubic lice infection.
In addition, in addition to others, their own health conditions should also be done well, usually pay attention to cleaning, reduce the residue of stains and dead skin, eliminate the living environment of pubic lice, and also reduce the probability of infection. However, if you do get pubic lice, the body will tell you through the symptoms.
Reminder: If the body presents with 3 symptoms, beware of pubic lice disease that may occur
The first: severe itching of the lower body
This is one of the most typical symptoms, frequent and intense itching of the lower body, indicating that the pubic lice are frequently stimulating the nerves during the process of foraging and reproduction, resulting in itching.
If it is also accompanied by dense bulges and redness and swelling of the lower body, it is more likely that there are symptoms of pubic lice, and it is timely vigilance.
The second type: bluish-gray spots appear
Pubic lice will suck a small amount of human blood during the process of foraging, and the blood will be concentrated, causing the capillaries to swell and take on a bluish-gray state.
Therefore, people with pubic lice disease often have blue-gray spots on the affected area. Take a closer look and don't miss the disease.
The third type: there are white, red, black hybrid bulges appear
Pubic lice take on different colors before and after foraging:
The eggs are white, black before foraging, and turn red after foraging (after blood sucking). Therefore, where there is a pubic lice infection, there will be often 3 colors of raised spots alternately. It can also be seen as a distinctive marker of pubic lice.
All in all, although pubic lice disease is not a serious disease, it is still necessary to be vigilant. Especially friends who usually have frequent itching of the lower body, pay more attention to whether there are hidden dangers. In case of really suffering from pubic lice, actively treat, use Lindan lotion and malathion lotion lotion for cleaning under the advice of the doctor, and I believe that you can quickly restore your health.
