Is it the pubic louse that has rust stains on the underwear? How to treat pubic lice effectively

Underwear is the clothing closest to women's private parts. Under normal circumstances, there will be traces of female vaginal secretion under the underwear. If the sanitary napkin is not replaced in time during the menstrual period, it may also be stained with blood. However, some women found some different marks on their underwear: rust stain. What the hell is this? This may be the pubic lice.

Rust stain on underwear is the main symptom of pubic lice

The so-called pubic lice, literally, are lice that live in the pubic region. This is an ectoparasite, which mostly sucks blood at night or in the quiet. The skin diseases caused by lice stinging the skin are called lice diseases, which are divided into head lice, body lice and pubic lice according to the different parasitic sites of lice.

The reason why there are rusty spots on the underwear of patients with pubic lice is determined by the living habits of pubic lice, "When the pubic lice suck human blood, they first pierce the skin with the tubular mouthpiece, enter the dermal capillaries, and then secrete saliva to prevent blood coagulation. While sucking blood, they leave dark red excreta. The saliva of the pubic lice can make the patient allergic and cause stubborn itching. Severe scratching can cause local bleeding, erosion and secondary bacterial infection. The skin at the pubic hair will also appear blue-gray spots, which is caused by the hemoglobin denaturation after the pubic lice suck blood The reason is that patients often have rust spots on their underwear. "

Therefore, if there is rust stain on the underwear and there is obvious itching in the private part, it is likely to be infected with pubic lice.

The lice disease can be transmitted by contact, and for the pubic lice, Director Zhang Qiushi said that the mode of transmission is usually sexual contact. "The pubic lice disease is a second-generation sexually transmitted disease, which can be transmitted through sexual contact. When sexual contact is made with a patient, the pubic lice attached to the pubic hair will crawl and transfer to the pubic part of a healthy sexual partner, and the lice eggs can also fall off in the pubic hair of the other person during sexual friction, and then hatch into adults, living by sucking human blood."

What if I get pubic lice? Expert: need joint treatment with husband and wife

If you find rust stains on your underwear or persistent itching in your private parts, it is recommended that you go to the hospital for examination. Generally, lice and lice eggs can be found from the pubic hair of the patient's underwear with the naked eye or a magnifying glass, which is also easy to distinguish from scabies, pruritus, pruritus, eczema, etc.

In order to cure the pubic lice thoroughly, the key is to completely kill the lice and eggs. Therefore, Zhang Qiushi suggested that both husband and wife or patients and sexual partners should be treated at the same time, "First, all the pubic hair should be shaved and burned off. Because of the poor heat resistance of lice, the internal clothes, quilts, towels, etc. can be boiled with boiling water to achieve the purpose of disinfection, and of course, all can be replaced with new ones. For the affected part, 50% of the tincture can be applied (30 grams of the Chinese medicine 100 parts can be soaked in 100 ml of 75% alcohol for 24 hours) 。 You can also use 10% sulfur ointment, Uniskin or Mijie Ling to achieve the purpose of disinfection. If there are skin lesions, you can give glucocorticoid or antipruritic agent for external use. "

Of course, Director Zhang Qiushi believes that prevention is better than treatment for pubic lice, and everyone should keep clean and put an end to dirty sex in daily life.
