What Are Pubic Lice (Crabs) and How Do They Spread?
“Crabs” are the common slang name for pubic lice. They’re small insects that live in the pubic hair of humans. This condition is considered a sexually transmitted disease, although that isn’t the only way they can be transmitted.
Experts estimate that approximately one million people catch pubic lice every year. It’s very common. The insect that causes it is called Pthirus pubis. It feeds on blood and its bites produce a very intense and bothersome itching in the genital area.
Interestingly, throughout history, some texts have mentioned the existence of pubic lice, even the Bible itself. Although they’re similar to head lice, the main difference is that these lice tend not to transmit any other disease. However, it’s a very uncomfortable infection that can also affect the social life of those who suffer from it. Therefore, in this article, we’ll explain everything you need to know about pubic lice and how they spread.
How do public lice act?
In most cases, pubic lice are spread sexually. However, the infection can spread in other ways.
As we mentioned above, pubic lice are small insects that live exclusively in humans, specifically in the genital area. Pubic lice have some resemblance to the shape of marine crabs. They adhere to the hair thanks to a substance that acts as cement. Once there, they bite the skin. The bite is so intense that it causes itching due to certain components of their saliva and feces.
Typically, symptoms manifest about a week after the infection. In addition to itching, it’s common for lumps and bumps on the skin to appear, as well as scratching-related injuries.
Although they often only affect the pubic area, pubic lice can spread to other areas. For example, it’s important to know that it can affect a person’s chest hair, armpits, or abdomen.
An important fact is that they can even appear in the eyelashes. This is common in children who have been sexually abused. Therefore, the presence of this type of lice in children sometimes guides pediatricians to cases of rape and sexual abuse.
How pubic lice spread
Experts tend to consider pubic lice a sexually transmitted disease. This condition is most commonly due to sexual contact with a person who’s already infected. However, this isn’t the only way they can spread.
Although less frequent, pubic lice can also spread by the use of certain clothing, sheets, or towels of an infected person. However, it’s almost impossible to contract the infection in areas such as bathrooms or toilets.
This is because this insect can’t live away from the human body for long periods. They need a temperature of approximately 82°F or higher to be able to survive. Still, anyone who has this infection should make sure to properly clean all nearby objects and clothing.
