Scabies is a contagious skin condition caused by a microscopic mite called Sarcoptes scabiei. The mite burrows into the skin and causes intense itching, which is usually worse at night.
Scabies is highly contagious and can be easily transmitted through close physical contact, such as sexual contact. It can also be spread through sharing clothing, towels, or bedding with someone who has scabies.
It is possible that your girlfriend contracted scabies from close contact with someone who has scabies or from sharing clothing, towels, or bedding with someone who has scabies. It is also possible that she picked up the mites from a contaminated surface or object.
If your girlfriend has been diagnosed with scabies, it is important for both of you to receive treatment to prevent the spread of the condition. Your doctor can prescribe a topical cream or lotion that can be applied to the skin to kill the mites and eggs. It is also important to wash all clothing, towels, and bedding in hot water and to vacuum carpets and furniture to remove any remaining mites.
